1 INTRODUCTION

M/s Indian Oil Petronas Private Limited (IPPL) is a joint venture company, promoted by two

FORTUNE Global 500 oil majors, one of them being Indian Oil Corporation Limited (IOCL)

and the other being Petroliam Nasional Berhad (PETRONAS), Malaysia, the national oil

company of Malaysia. On 2nd August, 2012 a LPG Import/Export Terminal was

commissioned at Ennore near Chennai to cater to the Southern part of India.

Currently, IPPL has proposed to increase its LPG throughput capacity by increasing the

number of shifts from one to three and by installing four additional truck loading decanting

(TLD) bays. The proposed expansion will take place at their Terminal located at Athipattu

Village, Ponneri Taluk, Thiruvallur District. The LPG throughput will increase from 5,76,000

TPA to 23,04,000 TPA.

The expansion requires Environmental Clearance from Ministry of Environment, Forests &

Climate Change under Category ‘A’ in the Schedule 6 (b) “Isolated storage & handling of

hazardous chemicals” of EIA Notification 2006 to commence the production. Letter issued by

SEIAA is enclosed as Annexure for reference. 1.1 NEED FOR THE PROJECT

India is the fourth largest consumer of LPG (15 million tonnes per year) in the world

following USA, China and Japan. With home deliveries of 3 million LP Gas cylinders per

day (900 Million/year), India is also the third largest domestic consumer of LPG. Since a gap

exists between demands and supply via indigenous production, nearly 22% of the LPG

demand in India is satisfied through import.

With a combined bottling capacity of 0.4 million TPA, Tamil Nadu was facing a LPG deficit

of 0.8 million TPA and this shortfall was met by transporting LPG from Mangalore by road.

IPPL has recently commenced operations at Ennore to meet the LPG requirements of Tamil

Nadu, Karnataka and Andhra Pradesh. The IPPL facility at Ennore was set up with the aim of

increasing LPG availability and eliminating transportation costs by bullet trucks.

1.2 BACKGROUND OF THE PROJECT

M/s Indian Oil Petronas Pvt. Ltd. (IPPL) has set up the Import/Export terminal at Ennore for

undertaking the following activities:


2

Import of Propane/Butane in refrigerated state in jetty through ship tankers and unloading

the same at the jetty.

Transfer of product through cross country pipeline and storing in dedicated refrigerated

tanks.

Transfer of product from tanks through pumps to heating train and then to online blending

system for production of Domestic LPG and Auto LPG.

Mercaptan dosing of the LPG and transfer to loading gantry for loading onto road tankers

for dispatch to destination.

IPPL have obtained Environmental Clearance from MoEFCC for the existing LPG

throughput capacity of 6,00,000 MTPA vide F.No. 11-76/2011-IA.III enclosed as Annexure

I. The Compliance Certificate for the existing EC condition from MoEFCC is enclosed as

3 PROJECT DESCRIPTION

3.1 OPERATING PROCEDURE

The operation of the terminal is as follows,

Ocean tanker unloading

Storage of product in refrigerated state

Terminal operation including loading

3.1.1 OCEAN TANKER UNLOADING

Propane/Butane will be received in parcels of 13500 MT to 26000 MT at the Jetty of Ennore

Port and will be pumped by ship tanker’s pumps @ 1000MT/hr through 2 nos. marine

unloading arms and will be transferred through 2 nos. cross country pipelines each having

total length of approx. 12.5 KM.

Propane/Butane will be stored in the refrigerated storage tanks which will have a net filling

capacity of 15000 MT of Butane and 15000 MT Propane.

The tanks operating pressures will be slightly above atmospheric pressure (1500 mm WCg).

Temperatures of (-)5oC and (-43)oC will be maintained in tanks for Butane and Propane

respectively. During unloading operation of the ship into the storage tanks, the flash vapour

displaced from storage tanks, from the heat coming from unloading pipes (both during pre-

cooling and ship unloading operation) enters into a re-liquefaction unit comprising of the


13

Flash Gas Compressors, Condenser, Receiver and mounded bullets etc. Re-liquefied

Propane/Butane is stored in the mounded bullets.

Both the unloading lines run parallel throughout the entire length from jetty to storage

terminal.

The critical parameters involved in operation of this terminal needs to be studied in details

considering the following:

Product is received in refrigerated state.

Cross country pipeline meant for product transfer from jetty to terminal is close to ambient

temperature.

Product shall be stored in refrigerated state.

Product shall be heated to 15oC prior to blending, mercaptan dosing and transfer to loading

stations.

The metal temperature inside the Propane/Butane feed-line increases proportional to the time

available between two ship unloading operations, due to heat ingress from the environment.

Heat ingress depends on the ambient temperature and the thermal conductivity of the

insulation. Pre-cooling of the two cross-country lines carrying Propane/Butane (also called

Propane/Butane feed-lines) is primarily necessary to prevent metal stress due to contact of

cold Propane/Butane delivered by the ship on the warm Propane/Butane feed lines.

The time required for pre-cooling is a function of the initial temperature inside the

Propane/Butane feed-lines and the ambient temperature. The state of the Propane/Butane in

this line depends on the degree of heat exchanged in the pre-cooling operation.

The pre-cooling operation is one of the requirements prior to the ship unloading operation.

The start of the ship unloading operation is ensured by the necessary checkpoints at the

source and the destination of the Propane/Butane feed-line. In this case, the source is the jetty

and the destination is the Propane/Butane storage tanks.

Cold Propane/Butane delivered by the ship is pumped by the ship’s pump from the jetty to

the Propane/Butane storage tank. The vapour generated, principally due to this unloading

operation, is drawn into the flash compressors located inside the battery limit wherein it is

compressed, liquefied and stored in Propane/Butane Receiver and then pumped to mounded

bullets as well as to refrigerated tanks in case of emergency resulting out of non-evacuation

from mounded bullets.


14

3.1.2 STORAGE OF PRODUCT IN REFRIGERATED STATE

The function of these tanks is to store butane or propane. Both these tanks are identical in all

respect and Propane/Butane can be stored in any of these tanks. But normally SR-01-01 will

be used for Butane and Butane rich mixture storage and SR-01-02 will be used for Propane

and Propane rich mixture storage. The capacity of each tank is 15000 MT. These tanks will

receive propane or butane from jetty. It is pumped by ship’s pump at a rate of 1000 T/hr,

through two nos. of marine unloading arm and transferred to storage tanks via 2 nos. of 18”

pipelines each having total length of approx. 12.5 km.

These tanks are vertical flat bottom, double wall, double integrity refrigerated tanks. The

tanks are normally operated at 500-1000 mmwc. Both the tanks are designed for propane

storage case, which is more stringent.

The Propane/Butane storage tanks (SR-01-1/SR-01-02) is operated at about 500-1000 mmwc

or just above atmospheric pressure. The tank is a double integrity cup-in tank construction

with a domed roof for the outer tank. Each tank shall have effective storage capacity of 15000

MT excluding dead level and vapours space. Since, both the inner and outer tanks are

designed for the same conditions, in case of failure of the inner tank, the outer tank acts as a

perfect secondary containment chamber, confining the inner tank contents in the outer tank.

3.1.3 TERMINAL OPERATION INCLUDING LOADING

The operation of terminal can be classified as follows:

Propane/Butane/LPG pumping

Propane/Butane/LPG heating

Static blender, blending control and mercaptan dosing

Product transfer to loading gantry for loading in road tanker

Sick tanker unloading

Product transfer to Indane bottling plant.

3.2 MAGNITUDE OF OPERATION

The proposed project is the increase in LPG production capacity within the existing facility

by tripling the number of shifts of operation and installing 4 additional TLD bays to achieve

the final LPG throughput of 23,04,000MTPA. The details of proposed and existing operation

are given in Table 3.1.

3.4 MANUFACTURING PROCESS

LPG production at IPPL consists of the following stages,

The products (Butane & Propane) are received in refrigerated state.

Cross country pipeline meant for product transfer from jetty to terminal is close to

ambient temperature.

Product shall be stored in refrigerated state.

Product shall be heated to 15oC prior to blending, mercaptan dosing and transfer to

loading stations.

3.4.1 PROPANE/BUTANE PUMPING

Each tank is provided with three pumps of capacity 220 m3/hr each. These pumps are

submersible, retractable and centrifugal pumps.

The pumps are provided for following functions:

Transfer of Propane/Butane to equipment house for heating and then to blending plant for

production of LPG followed by mercaptan dosing.

Pre-cooling (primary) of the cross country pipelines from jetty to the storage tanks.

Each tank is provided with automatic flow control valve meant for minimum flow return

and designated flow return to facilitate production of LPG of different ratio of Propane &

Butane.

Each pump column is provided with a provision both at the bottom and top with isolation

valves at top portion. This is meant for startup nitrogen purge operation.

3.4.2 PROPANE/BUTANE HEATING TRAIN

Since propane and butane have different boiling points they are stored in dedicated tanks at

different temperatures. Propane and butane are heated in separate heating trains to 15oC in

two steps.

Pre-heating of refrigerated propane liquid and butane liquid is done by condensing hot

vapours at 37oC to avoid freezing problems when direct heating with steam.

The propane used for heating propane/butane is vaporized in a kettle type propane vaporizers

by condensing steam. The steam condensate is used to heat the propane and butane to 15oC in

the exchangers. The propane vaporizers heat the propane to 37oC by LP steam at 1.0 Kg/cm2.


17

The condensate coming from the shell side of heat exchanger are collected in water

condensate receiver and transferred through pump to condensate polishing unit.

3.4.3 STATIC BLENDER & BLENDING CONTROL

After heating propane and butane to 15oC they are volumetrically mixed in static blenders at

a certain ratio (50% propane, 50% butane & 20 ppm Ethyl Mercaptan/Ton LPG) to produced

LPG. The ratio is determined by a processor and controlled by flow measurement in the

propane and butane discharge lines on downstream of the heating train. The presetting of the

flow rate is governed by the temperature in the tanks which are indications for the

composition. The vapour pressure of the mixture is supervised by continuous measurement

downstream the static mixture with the help of online vapour pressure analyzer.

If the vapour pressure of the mixture exceeds the desired one, the flow ratio of Propane &

Butane is corrected by blending control system and off specification product is returned back

to storage tanks.

The blended product is thereafter odorized by injecting Ethyl Mercaptan at a rate of 0.45 Kg

per 37.5 M3 of liquid LPG.

3.4.4 PRODUCT TRANSFER TO LOADING GANTRY FOR LOADING ON ROAD

TANKER

Pure propane, pure butane and blended LPG is filled into road tankers via loading arms.

There are two nos. filling gantries, total of 16 nos. (including 4 additional TLDs proposed)

loading points including Propane/Butane/Auto & Domestic LPG loading provision at

dedicated loading points. Sick tanker unloading facilities at one point in each gantry is also

provided.

Through integration with various sub-systems, which includes process, utility & safety, an

efficient automated control is achieved.

Normal loading sequence will be as follows:

First truck will enter the entry gate then it will be weighted and given receipt for the

related information. Afterwards the truck will enter bay area where it will fill the

specified weight of LPG as per loading rack computer. The filled truck will be sent to exit

gate where all commercial formalities will be carried out.


18

After getting information from loading rack computer field operator can now drain the

remaining LPG from pipeline into the drain collecting lines. Truck liquid arm can now be

removed from the truck.

Flow metering system for LPG loading to road tanker consist of strainer, vapour

eliminator, mass flow meter, set/stop control valve, batch controller, excess flow check

valve, card reader and vehicle grounding.

3.4.5 PRODUCT TRANSFER TO INDANE BOTTLING PLANT

The blended LPG is also transferred to adjacent Indane bottling plant through pipeline.

Through integration with various sub-systems, which includes process, utility & safety, an

efficient automated control is achieved.

Flow metering system for LPG transfer to bottling plant consist of mass flow meter with

temperature and density correction, excess flow check valve and automatic shut down/remote

operated valve.

The process flow diagram is shown in Figure 3.1.

There will be an increase only in domestic wastewater generation due to an increase in the

number of drivers. The additional quantity of wastewater will also be treated in the existing

Sewage Treatment Plant (treatment capacity 80 KLD) which is adequate to handle the

additional quantity of effluent.

The layout of the Sewage Treatment Plant is given in Figure 4.1.

The Characteristics of the raw sewage at present is as below:

pH - 4.5 to 7

Suspended Solids - 600 to 700 mg/l

Oil & Grease - 2 to 5 mg/l

COD - 500 to 600 mg/l

BOD (3 Days at 27oC) - 400 to 600 mg/l

The Characteristics of the sullage at present is as below:

4.4.2.2 EFFLUENT GENERATION, TREATMENT & DISPOSAL

Currently IPPL utilizes raw water for two major industrial activities, (i) operating the DM

Plant and (ii) operating the Cooling Tower. The DM Plant provides feed water to the Boiler

which generates effluent in the form of blow-down water.

Blow-down water from boiler water is directly disposed to the solar evaporation pond. Blow-

down water from DM plant & Cooling Tower water is treated using RO plant which in turn

produces permeate and reject water. RO permeate is recycled to DM plant and the reject

water is diverted to solar evaporation ponds.

After the expansion, raw water will be used exclusively for operating the Cooling Tower.

Effluent will be generated from blowdown of the DM Plant and Cooling Tower. There will

be no change in the quantity of effluent generated and so the same disposal practices will be

followed.

4.4.3 SOLID & INDUSTRIAL WASTE POLLUTION CONTROL MEASURES

4.4.3.1 SOLID WASTE

4.6.2 STORM WATER MANAGEMENT SYSTEM

Storm water run-off from roads/paved/landscaped areas is being directed to Rain Water

Harvesting Pond. The storm water management in this facility ensures that the project site

does not get flooded. This can be achieved by design, construction and maintenance of the

drain using best engineering practices. The storm run-off does not get contaminated. This is

realized by keeping the areas clean the drains periodically. Spillage of fuel/oil from storage

places will be properly managed. The layout shows the rainwater harvesting & storm water

management system is given in Figure 4.3
