    1.0 ABSTRACT

    PPD are used as lubricant additives for crude oils. In low temperature and winter

    conditions, waxes in crude oils will deposited and congeal the pipelines and production

    equipment during transportation and production. EXZA Company Sdn. Bhd. is producing

    PPD for oils and gas industries to help these industries solve the problem of oils

    transportation. This report details on the expansion of the chemical plant of EXZA Company

    in order to incorporate new technology used to manufacture PPD. Organization chart of the

    company is also included into this report. The report will be focused on the development of

    new facilities to produce new type of PPD; namely the EVA-based aqueous PPD

    dispersion. Details on the process, equipment and economy prospects were encrypted in

    this report.

    2.2 Logistics

    What is logistics? Logistics is the part of the supply chain process that plans,

    implements and controls the efficient flow and storage of goods, services and related

    information from the point of origin to the point of consumption, in order to meet the

    customers requirements. Logistics industry is one of the catalysts for the development of

    industrialization in Malaysia which is linked to the international trade. In Plant Design,

    location or geographic of a plant is one of the very crucial factors to determine the

    successful of any chemical business venture.

    Based on few considerations, the ideal location of our plant is at Parit Buntar,

    Perak. Figure 1 location of our plant. The details are displays in below:

    Address: Lot 123, Jalan Perusahaan SatuDuaTiga, Kawasan Perusahaan Parit Buntar,

    34200 Parit Buntar, Perak Darul Ridzuan, Malaysia.

    Size: 87120 square feet (8093.7128 m2)

    Cost: RM 4,500,000 = $1,230,147.41

    There are many factors must be considered during selecting the desired plant site of

    a plant. The location of plant should be:

    Good access to liquids-rich natural gas resources, water, road and rail transportation

    infrastructure

    Be a good scope for plant expansion and a conducive environment, safe living

    conditions for easy plant operation

    A safe living conditions for plant personnel as well as the surrounding community

    Power grids, economics, and sufficient acreage to accommodate facilities for a world-

    scale petrochemical complex and potential future

    Raw material availability: some of the raw materials required like Ethylene Glycol is in

    the vicinity of the plant location. Besides, Parit Buntar is near to Penang jetty too which

    it makes the transportation of raw material, equipment, and finish product more easy

    and convenient.

    Reasonable land price: after compare few industrial land in Parit Buntar, we found that

    this land sell at the lowest price which is RM 40 per square feet. Table 1 displays the

    land tax capacity and land tax effort indices by state governments in 2008. It can be

    seen that Perak is having the moderate land tax capacity. This is beneficial for the

    company future development.

    Good source of utilities

    Excellent infrastructure and transportation: near to jetty, highway and railway.

    Government incentives: Malaysia government encourages the establishment of more

    new plant by giving special incentives. One of the incentives given is a 5 year

    exemption on import duty. A company will be given the opportunity to apply for

    Investment Tax Allowance (ITA). An allowance of 60% are given on its qualifying capital

    expenditure (such as factory, plant, machinery or other equipment used for the

    approved project) which incurred within five years from the date on which the first

    qualifying capital expenditure is incurred. This exemption would help the company save

    a lot of expenditure as most of our equipment are bought over from other country such

    as China. Besides, from Malaysia Industrial Development Agency (MIDA), our

    companies are eligible for Pioneer Status in which the company can offset this

    allowance against 70% of its statutory income for each year of assessment. Any

    unutilized allowance can be carried forward to subsequent years until fully utilized. The

    remaining 30% of its statutory income will be taxed at the prevailing company tax rate.

    In addition, when purchasing the land, 20-50% of discount is offered by the state

    government base on the plant location, size of area, number of job created and value of

    purchase. Another type of incentive given is the discount on monthly electrical bills for

    the first 2 years.

    3.0 PRODUCT SPECIFICATIONS

    Pour point depressant (PPD)

    Our company excels in manufacturing EVA-based PPD for many years. The PPD

    produced are of dispersion type and based on ethylene vinyl acetate (EVA) copolymer of

    specific range of vinyl acetate content. Below is the technical specification of the PPD

    produce by EXZA Company.

    4.1.1 Polymer Ethylene Vinyl Acetate (EVA)

    Figure 4.1: The structure of EVA copolymer

    EVA is a copolymer of ethylene and vinyl acetate. The two key parameters that

    determine their properties are weight percent vinyl acetate in the copolymer and melt index

    (MI). As more vinyl acetate (VA) is added to the polymer, it disrupts the polyethylene

    crystallinity, which in turn lowers the melting point, modulus, and hardness. The VA makes

    the polymer more polar, which improves adhesion to polar substrates and aids in solubility.

    In the case of application of EVA as pour point depressant of crude oil, a specific

    value of VA content and melt index are required in order to increase its efficiency during the

    injection. Table 4.2 shows the characteristic of EVA used in the formulation of PPD

    aqueous dispersion in EXZA Company.

    The EVA copolymer resins used in manufacturing of aqueous PPD dispersion in

    EXZA Company comes in the form of small, free flowing pellets. At ambient temperature,

    the EVA resins are quite inert, and resistant to attack by most aqueous acids and bases.

  • 15

    The EVA resins used have a maximum handling temperature of 230oC. If exposed

    to elevated temperature, EVA resin may undergo thermal degradation; in which it will

    release fumes consist of possible decomposition product such as acetic acid, carbon

    monoxide and acrolein which are highly toxicant. However, in the case of the processing

    temperature applied during the manufacturing process which is of range 150 to 160oC

    we believe this hazardous condition can be easily avoided.

    4.1.2 Solvent 2 ethylhexanol

    Figure 4.2: The structure of 2 ethylhexanol

    2-ethylhexanol is an eight-carbon branched chain O-X-O alcohol having a high

    boiling point and slow evaporation rate. It is a versatile solvent featuring excellent reactivity

    as a chemical intermediate. It has low water miscibility and appears as colorless liquid -

    functions as solvent in order to aid the melting process of EVA copolymer resins during the

    manufacture of aqueous PPD dispersion. It also acts as the main dispersing medium which

    will later diluted by the addition of water in order to reduce the overall cost of PPD

    produced.

    Recommended dosage 30 65 wt.%

    2-ethylhexanol is immiscible (disperse) to EVA. This property will lead to a better

    cold flow dispersion emulsion where the PPD is suspended as micrometer sized solid

    particles in an aqueous-based alcohol (OH) carrier fluid; whereby it is suit to be applied at

    temperature of -20 to -40C. Besides, this solvent was found suitable to be use in our PPD

    formulation due to its higher boiling point that easily surpasses the processing temperature.

    This will ensure the solvent can maintain its liquid state during the processing.

    4.1.3 Dispersing agent Sodium Oleate

    Figure 4.3: The structure of Sodium Oleate

    Sodium oleate is the sodium salt of oleic acid, a monounsaturated fatty acid used as

    anionic surfactant and emulsifier inside the PPD manufacturing process. It is mainly used

    as agent to disperse the non-soluble ingredients inside the medium of the aqueous PPD

    dispersion. As such, there are some requirements needed in order to achieve its maximum

    effect, as listed in Table 4.4 below.

    4.1.5 Stabilizing agent Ethoxylated Nonylphenol

    Ethoxylated Nonylphenol is a non-ionic surfactant used as stabilizing agent inside

    the aqueous PPD dispersion manufactured by EXZA Company. It functions as agent to

    stabilize the whole dispersion system of the product across a broad spectrum of conditions.

    It also provides shear stability protection to allow the product to be transferred via a number

    of different pumping systems, as well as maintain its stability during transportation period.

    In EXZA Company aqueous PPD dispersion formulation, water is used as

    secondary medium of dispersion, due to the purpose of diluting the main dispersing

    medium; 2-ethylhexanol. This step is essential in order to reduce material cost and

    consumption, as well as to reduce the toxicity of the product produced.

    4.2 Material shelf life and quality assurance

    EXZA Company concerned about quality. Thus, the shelf life and quality of each raw

    material received by our supplier was strictly taken into account. Table 4.7 shows the

    durable time and proper storage handling for each raw material. This information is

    important in order to keep tab on our feeding material supply and helps estimate the

    production capability during peak time.

    Upon the arrival of raw material in the facility, few tests need to be run in order to

    ensure we received the right material according to the requirement listed for processing.

    This step is important in order to avoid faults and contamination during the storage and

    processing period, as well as it serves as proves in case if any misunderstanding happens

    with the contracted supplier. Table 4.8 listed the necessary test need to be run during QA

    analysis of the raw materials.

    5.0 PROCESSING SYSTEM

    5.1 Process description

    Figure 5.1 shows the process flow diagram of the production of EVA-based PPD.

    The process incorporate in this facility is a new technology of mixing, namely 2 step

    process mixing. This technology shortens the mixing time by opting out melt kneading

    process; in which usually used in order to prepare any type of dispersion.

    The process of preparing the EVA-based PPD dispersion begins by melting the

    copolymer of EVA inside the mixing vessel, aided by using 2-ethylhexanol as the main

    solvent. This process is carried out at elevated temperature suitable with the standard

    melting point of EVA copolymer used.

    Upon the completion of melting process, the temperature of process is brought

    down to 70oC in order to avoid any ignition during the addition of dispersing and stabilizing.

    After another several minutes of mixing, a mixture of ethylene glycol and water of specific

    ratio are added inside the vessel, and the mixing process continues until it achieves

    homogenization. Note that the mixture of ethylene glycol and water was mixed beforehand,

    and added inside the mixing vessel as soon as the heating system is turned off.

    When the PPD dispersion inside the mixing vessel achieves desired

    homogenization, it is then transported to the PPD storage tank according to the respective

    grade produced. During this transportation process, the mixture will pass through an in-line

    mixer for particle size reduction purposes. This is to increase the effective rate of the PPD

    produced and keep the dispersion stable for longer storage duration.

    During the entire process operation, a suitable heating and cooling system are used.

    Proper safety system is being implemented in order to constantly monitor the hazard and

    risk present during the process. Cleaning and maintenance are carried with strict schedule

    in order to contain and avoid any risk of accident occurring inside the facility. Waste

    treatment system is also incorporated inside the plant in order to maintain a pollution-free

    environment.

    5.2 Standard operation procedure

    The mass flow rate of each component is set according to Table 5.1 as well as the pre-

    determined temperature for the mixing process. Next, the procedures of operations are as

    follows:

    1. The addition of solvent into the mixing vessel by releasing the valve incorporated

    inside the pipeline. On the same time, switch on the vacuum conveyer in polymer

    feeding system.

    2. The heater is switch on at 10oC/min heating rate. On the case of desired loading

    and melting temperature of 150oC is achieved, the mixer was then turned on and

    the melting process occurs for 1 hour.

    3. Upon approaching the end of melting process, the temperature is renewing to 70oC

    at cooling rate of -10oC/min. After approximately 10 minutes, both dispersing and

    stabilizing agent are added into the mixing vessel by releasing the valve

    incorporated inside the pipeline and mixing process continues for another 15

    minutes.

    4. At the same time of the start of cooling process, the pre-mixing process of EG and

    water will occur in different vessel. Both component are added inside the vessel by

    releasing the valve incorporated inside the pipeline at the given flow rate (refer

    Table 1). The mixing temperature inside this vessel is set to follow the standard

    room temperature (according to country climate).

    5. After approximately 30 minutes since the start of cooling process, the EG and water

    mixture is added inside the main mixing vessel and the mixing process continues for

    another 20 minutes. Note: The heater is turned off at this point allowing the mixture

    to cool down to room temperature.

    6. The mixer is then turn off and the valve is open to allow PPD transportation into

    storage tanks. During this step, the product will pass through the in-line mixer

    incorporated along the pipeline system for particle size reduction purposes.

    7. The PPD mixture that passed the QC inspection will later be stored inside the

    storage tank before proceed to packaging line.

    5.4 Waste treatment

    In terms of waste, the production of EVA-based PPD dispersion is expected to

    produce zero chemical by-products. However, in case of accidental or damage product, the

    disposal of the said PPD should be strictly taken care of.

    In terms of contamination or leaking, the product must be disposed or incinerated in

    accordance with local regulations. Disposal of said PPD are usually handle by licensed

    waste disposal contractor due to its non-recyclable nature and toxicity upon contact.

    Next, although the heat release during process cant be count as waste, it still

    counts as by-products. These heat generated are used for energy recovery system in order

    to minimized the cost used to power up the whole facility.

    Due to extensive usage of water inside the PPD manufacturing process, EXZA had

    developed an additional system for water waste treatment. In this part of the plant, waste

    water is collected and transferred into multiple condensers in order to separate the waste

    substances from it. This treated water is then can either be reused for other purposes or

    released out of the plant through the drainage system.

    6.0 Processing equipment and sizing

    According to the process flow diagram (PFD) in the Figure 5.1 above, it shows the

    equipment needed in order to complete the process of the PPD. This report intends to deal

    with specific information of continuous PPD manufacturing process and a production unit to

    produce optimum 36 tons per day by 2 production line of PPD product. In order to produce

    the PPD product, the equipment is classified into unit operations that consist of important

    equipment.

    1. The storage tanks of the feeding material and PPD product

    2. The mixing vessel unit

    3. The In-line mixer unit

    4. The piping system

    6.1 The storage of the feeding materials and PPD product

    All raw materials are brought on site and stored in warehouse then transfer to the

    storage tank. Storage tanks used in PPD manufacturing process normally is stainless steel

    and carbon steel material. This is to prevent the raw material has chemical reaction with the

    storage tanks which will affect the properties of the final product. The storage tank that

    been use are actually consist of several type, this is due to the type material that been

    stored in the storage tank (refer Figure 5.1). The storage tanks of the raw material consist

    of 6 type of storage tank which is:

    A. The polymer (EVA) silo storage tank

    B. The solvent storage tank

    C. The dispersing agent storage tank

    D. The stabilizing agent storage tank

    E. The anti-freezing storage tank

    F. The PPD storage tank

    In order to solve the problem of flow rate of the EVA feeding process, the

    gravitational system is used due to its efficiency and superior economical aspect. Thus,

    below are the properties of all the storage tank that been used during the manufacturing of

    the PPD product. All of the storage tank for liquid form of the raw materials such as the

    solvent, dispersing agent, stabilizing agent and anti-freezing agent are been stored in the

    same type of storage tank but in different of size and the capacity of the tank.

  • 29

    A. EVA silo storage tank

    Figure 6.1 shows the EVA storage tank used for the PPD manufacturing. The

    storage tank use to store EVA is named as silo tank; which is suitable for storing bulk

    materials. Silo tank used in PPD manufacturing are made from stainless steel to prevent

    chemical reaction occur during storage time. Table 6.01 shows the specification of the silo

    tank. Silo tank actually been closed at the top of the tank, this is because the safety

    precaution that must be follow in order to avoid contamination and any problem occurs

    during the manufacturing. EVA is in the solid form of material and cannot be expose to

    direct sunlight as it may reduce its properties and may produce hazard.

    Figure 6.1: EVA Silo tank

    Loading EVA into silo tank can be carried out by the drivers themselves with

    automatic loading end when the nominal value is reached. This can be seen from Figure 6;

    whereby the EVA is transport from the warehouse by lorry and pumped into the silo tank.

    Silo tank will be place at 45o above the mixing tank in order to transfer the EVA into

    the mixing tank. This is to solve the difficulties faced during the feeding of the EVA which

    comes in solid form; by using gravitational system of silo tank so that the flow rate of EVA is

    mainly aided by gravity. This method contributed to reduction of cost of overall polymer feed

    system due to lesser energy consumption and accurate control system.

    6.2 The mixing vessel unit

    During the manufacturing of PPD, homogenizing vessel is used in order to melt the

    EVA and mixed the entire ingredient needed to form the product. Thus, several type of the

    mixing vessel has been selected and went through the preliminary process in order to

    determine which one is suitable for our process.

    EXZA Company had chosen mixing vessel produced by Foshan JCT Machinery

    Co., Ltd. This is because the specification and the quality of the vessel are on par with our

    requirement as its price is also cheaper compared to the others.

    Furthermore, the mixing process need to be done in certain temperature and

    pressure; which we found that this type of homogenizing vessel is easy to deal with the

    temperature problem and control. Below are the picture of the mixing vessel that been

    choose in order to mix the ingredient and to manufactured our PPD product.

    Figure 6.5: Homogenizing vessel

    Referring to the Figure 6.5, the mixing tank is of simple design and consists of rotor

    which comes in layer. This plays an important role in mixing in order to achieve the best

    quality of our product. Below are the properties and the specification of the mixing vessel

    that has been chosen by our company.

    6.3 In-line mixer

    During manufacturing of PPD, the size particle of PPD during mixing process inside

    the homogenizing vessel is big. This is because the solvent and the EVA does not yet

    completely dispersed, thus the reduction of the particle is needed in order to reduce of the

    particle size of the EVA and other material. This reduction in particle size also important in

    order to make sure the stability of our product is in the good condition.

    To reduce the particle size, In-line mixer is used in order to get more nano-particle

    of our final PPD product and save time. High Shear In-Line mixers are supremely efficient

    and rapid in operation and are capable of reducing mixing times by up to 90%.

    The high-speed rotation of the rotor blades within the precision-machined mixing

    workhead exerts a powerful suction, drawing liquid and solid materials into the rotor/stator

    assembly. Centrifugal force then drives the materials towards the periphery of the workhead

    where they are subjected to a milling action in the precision-machined clearance between

    the ends of the rotor blades and the inner wall of the stator.

    This is followed by intense hydraulic shear as the materials are forced, at high

    velocity, out through the perforations in the stator, then through the machine outlet and

    along the pipework. At the same time, fresh materials are continually drawn into the

    workhead, maintaining the mixing and pumping cycle. Figure 6.6 shows the In-line mixer

    used.

    Figure 6.6: In-line mixer

    There are many type of In-line mixer in the market nowadays. However the In-line

    mixer produced by Silverson has been selected by our company. Below is the specification

    In the piping system, there are equipment incorporated which plays an important

    role in transporting and controlling the material flow centrifugal pump and valve.

    Centrifugal pump help to pump the raw material of PPD from storage tank of feeding

    material to the mixing vessel and later, towards the storage tank of PPD by pressure. The

    valve is to control the amount of the feeding material allowed to flow inside the pipeline.

    All manufacturing processes are to some extent hazardous, but in chemical

    processes there are additional, special, hazards associated with the chemicals used and

    the process conditions. Thus being said, any organization should have a legal and moral

    obligation to safeguard the health and welfare of its employees and the general public.

    Loss prevention is an insurance term, the loss being the financial loss caused by an

    accident. This loss will be not only the cost of replacing the damaged plant, paying fines,

    and settling third-party claims, but also the loss of earnings from lost production and lost

    sales opportunities.

    In the event of a major incident, such costs can be large enough to overwhelm a

    company. Thus, safety system is implemented inside the facility in order to avoid such

    losses, and reduced the said risks to acceptable levels.

    7.1 Instrumentation and Control Systems (I&C systems)

    In EXZA plant, I&C systems is used for safety purposes. I&C systems incorporated

    inside the facility are developed based on the data collected during hazard and operability

    studies (HAZOP) carried out in the process design stage.

    They are accomplished, as appropriate, using the structures, systems and

    components provided to mitigate the consequences of accident conditions. I&C system

    does not only focused on monitoring the safety of plant operation, it also gives control on

    the production rate and cost, as well as provides information on overall energy consumption

    of the facility.

    However, I&C system is mainly developed to give accurate control on the equipment

    present in the facility. Ultimately, process control and monitoring are closely related to

    safety, in which I&C system helps;

    To keep the process variables within known safe operating limits;

    To detect dangerous situations as they develop and to provide alarms and

    automatic shutdown systems;

    To provide interlocks and alarms to prevent dangerous operating procedures

  • 44

    7.1.1 Types of I&C system in plant

    On the basis of the identification of safety functions that are required to be carried

    out, I&C systems are established to perform functions important to safety. There are some

    types of instruments implemented in order to monitor and relay information in case of

    accident and potentially hazardous deviations in process condition. Some of them includes;

    1. Alarms system

    2. Automatic trip system

    3. Interlock system

    7.2 Emergency Situation Procedure

    Accidents could be happened regardless of time and place. It is classified in

    emergency situation which consider as out of control. Therefore it is a need to list the

    emergency procedure guideline that is used in EXZA plant.

    General Procedure

    Some of the procedures that must be taken when the emergency situation happened in the

    plant are:

    i. Do not panic and stay alert.

    ii. Assess the situation around your area.

    iii. Wait for instructions from supervisor or shift manager.

    Fire/Explosion/natural Disaster

    This procedure should be taken for fire, explosion or natural disaster are the same. The

    basic procedures for the above situation are:

    i. Raise the alarm.

    ii. Immediately inform the supervisor or shift manager.

    iii. Assess the situation.

    iv. Wait and follow the instruction from them.

  • 45

    Hazardous Substance Discharge

    If any hazardous substance discharge incident occurred, without taking any unnecessary

    personal risk, the following procedure had to be followed:

    i. Immediately inform the supervisor or shift manager

    ii. Minimize substance discharge

    iii. Identify substance and act accordingly

    iv. Neutralize the substance discharge

    v. Wait for the instructions from supervisor or shift manager

    8.0 ECONOMIC POTENTIAL

    8.1 Total Capital Investment

    We have divided the total capital investments into 2 parts in the early stages of plant

    design, which are fixed capital investment and working capital investment. The fixed capital

    investment is investment in fixed capital or to the replacement of depreciated fixed capital.

    Thus, fixed capital investment is investment in physical assets which includes the cost for

    machinery, land, services, vehicles and installation. The total fixed capital investment costs

    Exza for about $ 2,165,288.16 which include the direct and indirect cost. The working

    capital investment is 15% from the fixed capital investment.

    It is including the costs necessary to operate the plant. Working capital investment is

    crucial to make sure that EXZA has sufficient funds for carrying out our everyday operations

    in a smooth manner. Generally, working capital investment is simply 15% of the fixed

    capital investment.

    Working capital investment = 0.15 x fixed capital investment

    = 0.15 x $ 2,165,288.16

    = $ 324,793.23

    8.4 Material Consideration

    In Exza, we produce 3 tonnes of pour point depressant (PPD) for each cycle and 18

    tonnes per day by one production line. One day 6 cycle, 1 week 5 working days. 1 week

    will produce 90 tonnes PPD by one production line. The entire tank for storing the material

    can be filled up to 2 weeks of production of PPD. Therefore, for every two weeks of

    production, the supplier will filled up the entire materials tank.

    After considering all the terms and conditions required by both of the bank, we

    decided to choose UOB as it provides a better efficiency in withdrawing the loan. Besides,

    the repayment is flexible over the loan tenure. EXZA targets to pay the loan quicker so that

    the loan is expected to completely pay back within 10 years instead of 15 years.

    UOB also provides lower interest rate as daily rest interest rate is an advantage due

    to calculation based on the previous days outstanding balance. Thus, if we make

    outstanding payment in the middle of the month, it will reduce the loan interest at the next

    day.
