3. Need for the project and its importance to the country and or region
Utilization of molasses for the production of ethanol in India will not only
provide value addition to the by-product, it also ensures better price stability and
price realization of molasses for the sugar mills. This will improve the viability of
the sugar mills, which will in turn benefit to cane growers.
Industry overview
Molasses is one of byproducts of sugar industry which is used to produce
rectified spirit/alcohol for making liquor and fuel. Traditionally, molasses has
been used in India to produce rectified spirit and alcohol of higher than 95%
purity for producing liquor for human consumption and for producing various
chemicals. However, with technological developments in the recent past,
molasses has been effectively used to produce bioethanol for blending with
petrol as a fuel
Global scenario
Brazil is the second largest producer of ethanol globally after U.S. While
U.S. produces ethanol from corn, Brazil manufactures ethanol from sugarcane.
Brazil has mandatory blending ratio of ethanol in gasoline ranging from 18% to
25%. The blend rate was as high as 25% before September 2011 and was reduced
to 20% due to drop in cane output hence affecting the ethanol production.
Currently, flex-fuel cars, which can use either ethanol or blended gasoline, in
Brazil account for about 53% of the total car fleet and around 90% of the new
vehicles sales. The proportion of the flex-fuel cars are expected to cross 80% by
2020. Currently, the Brazilian light vehicle fleet has been increasing by 6.7% y-o-
y since 2003 with currently 90% of the new vehicles being flex-fuel cars. Thus,
there exists an increasing demand in Brazil for ethanol which is encouraging for
the sugarcane industry.
Indian scenario
India has about 330 distilleries, which produce over 4 billion liters of rectified
spirit (alcohol) a year. Beyond total distilleries, about 120 distilleries have the
capacity to distillate 1.8 billion liters (an additional annual ethanol production
capacity of 365 million liters was built up in the last three years) of conventional
ethanol per year which is sufficient to meet requirement for 5% ethanol blending
with petrol.
Government policy
In 2006, GOI mandated 5% ethanol blending with petrol, EBP programme to
directly benefit the sugarcane farmers by assuring the sugar industry a stable
and reasonable return for the molasses and then passing a significant part of the
same to the farmers. But since then the programme has been struggling to take
off despite the fact that the Cabinet Committee on Economic Affairs (CCEA) in
November 2009 directed that a financial penalty be imposed on oil marketing
companies for their failure to reach targets. In November 2012, the CCEA has
made it mandatory for Oil Marketing Companies (OMCs) - Bharat Petroleum,
Hindustan Petroleum and Indian Oil Corporation - to blend 5% ethanol with
petrol. This is likely to reduce the fuel import bill and lower India's dependence on
fossil fuel as the ethanol prices are lower than petrol. The OMCs have been
blending ethanol with petrol for the past two years but the policy was partially
implemented in absence of any clear directive. The committee, headed by the
Prime Minister, has also approved market-based pricing of the biofuel,
opening the market for ethanol producers - mostly sugar companies. This shall
result in an increased demand for ethanol by OMCs.
The national bio-fuel policy, approved by the Government of India, has plans for a
20% ethanol blending programme by 2017 from the current mandated 5%
blending & recently increased to 10%, to reduce India’s dependence on fossil fuel
imports.
4. Demand –Supply Gap
The gap between the availability of alcohol and the requirement by the industry
has been widening. The existing requirement of alcohol by the industries is
around 450 crore liters annually at 10% fuel ethanol blending, industrial alcohol
and potable alcohol and the production is around 285 crore liters. The trend is
increasing as the blending increases. The Ministry of Petroleum recently issued
gazette notification dated 11th Januray 2013 making 5% ethanol blending with
petrol mandatory across the country. Year Ethanol production Ethanol utilization Ethanol

10% 2078
20% 4157
From the above table it can be concluded that actual production of ethanol in India has not kept pace with the demand. Also with robust growth for chemical and potable industries it will mean greater shortage of ethanol in the coming years ahead. The Government of India has set an indicative target of 20% blending of ethanol with petrol and also for diesel with biodiesel across the country by 2017.
5. Imports Vs. Indigenous Production
No import is proposed as demand in domestic market is enough to
consume the product.

09/05/2006. Ethyl alcohol is basically used for three purposes i.e. 1) Industrial
alcohol for production of downstream chemicals, 2) Pptable Alcohol for
mamifacture of alcoholic beverages (Country Liquor and IMFL) and 3) Fuel
ethanol or Anhydrous alcohol, which can be blended with petrol or diesel.

Industrial Alcohol: -
Ethyl Alcohol is an Important feedstock for the manufacture of
chemicals.
World ethyl alcohol consumption for the production of chemicals is
around 1%. These chemicals are primarily the basic carbon based
products like Acetic acid, Butanol, Butadiene, Acetic Anhydride, Vinyl
Acetate, PVC etc. The existing plants such as synthetic rubber
requiring large quantities of alcohol will certainly grow to a large
capacity. Acetic acid & Butanol, which are needed in pharmaceuticals,
paints & in many other areas are important industries as they are value
added products. Ethylene, Ethylene oxide & Mono-ethylene glycol are
also produced from petrochemical route. However latest technological
development & taking into account the increasing cost of petrochemical
raw material, it is now possible toproduce Ethylene oxide, Mono-ethylene
glycol etc. starting from ethanol.
During the last 5-6 years, a number of alcohol-based industries have come
up& the existing has marginally expanded. The raw material needs
of the alcohol based chemical industry have to be niet to facilitate
maximum capacity utilization of these units in order to meet the
domestic demands for the end products. These units are starving for
want of raw materials. The shortage is wide spread & it has hit a most of
chemical drug & other industries. The drug industry is also bedeviled by
scarcity of industrial alcohol. Producers of insulin, antibiotics, tonics &
several other essential bulk drugs & finished formulations are unable to
obtain their quota of industrial alcohol, which is a vital raw
material for them. Thus, even in Maharashtra, which should be a
State with surplus production of alcohol, drug & chemical units are in
the group of acute shortage of industrial alcohol. It follows that the
supply of industrial alcohol to chemical and drugs units in the country
will remain below normal for some more time. In order to maintain
proper rate of growth of industries, production of alcohol must
increase.

Following is a brief description of the process:
Detail Process Description & Process Flow Charts
Fermentation
Molasses, diluted with water to the desired concentration is metered continuously
into a single tank fermenter. Additives likes urea (in the form of pellets or prills)
and defoaming oil are also introduced in the fermenter as required. There is an
automatic foam level sensing and dosing system for defoaming oil.
Every Kilogram of alcohol produced, generates about 290 Kcal of heat. This excess
heat is removed by continuous circulation of fermenting wash through an
external plate heat exchanger called the Fermenter Cooler. The fermenter
temperature is always maintained between 32 and 35 deg. C, the range optimum
for efficient fermentation.
The yeast for the fermentation is initially (i.e. during start-up of the plant)
developed in the Propagation Section described further on. Once propagated, a
viable cell population of about 500 million cells/ml is maintained by yeast
recycling and continuous aeration of the fermenter. Fluctuations in the yeast
count of +/- 20% have little effect on the overall fermenter productivity. Yeast cell
vitality which is usually above 70% may, in times of stress (such as prolonged
shut-downs) drop to 50% without affecting the fermentation.
Fermented wash passes through a series of hydro cyclones (one to three or
move in number depending on plant capacity), which remove grit, iron filings
and similar heavy particulate matter. This rejected material along with some
wash, is taken to the bottom portion of the wash column for alcohol recovery.
The overflow from the first hydro cyclone is taken a wash tank, also provided
with an arrangement to facilitate removal of heavy settable particulate matter.
Overflow from the wash tank is taken to the yeast separator, which clarifies the
wash. The hydro cyclone and the wash tank protect the separator from erosion
damage by removing grit and similar hard particles.
Wash Preparation
For the plant mash, molasses is diluted with water to give a sugar concentration
of 14 to 18% and pumped directly into the fermenter. This mash is usually not
sterilized, although in certain cases it has been pasteurised with a resultant
slight increase in efficiency. The fermenter is issued when it is one eighth to one
fourth full with a large volume of active yeast. 2 to 4% of the final volume to
allow development of the yeast during the entire filling period, which may
amount to 8 hours and to avoid growth of contaminating organisms during
this period.
Nutrients
Blackstrap molasses usually contains enough yeast nutrients to give a fast,
efficient fermentation. In some cases, however, it is desirable to add small
quantities of ammonium salts, such as ammonium sulphate, to the mash to
increase the rate and efficiency of the fermentation. In such cases, the amount
of ammonium sulphate added varies between 0.5 liters and 3 liters per 10,000
liters of mash, depending on the molasses used, the optimum amount being
determined by laboratory in a blackstrap molasses fermentation.
Fermentation Temperatures
Fermenters are usually set at a temperature between 27º F and 30º C and are
held a 32º C by the use of water sprays on the rank internal cooling coils, or by
circulation of the mash through external coolers. It is desirable to maintain the
temperature of the mash below 35º C. The amount of heat liberated during
the fermentation agrees with the theoretical value. C2H12O 2C2H5OH + 2CO2+26.0 Calories
The heat produced from a fermentation involving 100 kg of sugar is 260 cal.
If the fermenters are not cooled the temperature of the mash will rise as much as
40º C.
• Yeast Recycling:
The yeast in the fermented wash is removed as a 45 to 55 v/v slurry, and is
returned to the fermenter. This feature ensures that a high yeast cell
concentration is achieved and maintained in the fermenter. By recirculating
grown, active yeast, sugar that would have otherwise been consumed in yeast
growth, is made available for alcohol production, ensuring high process
efficiency.
• Propagation:
The propagation section is a feeder unit to the fermenter. Yeast, either
Saccharomyees cereviseae or Schizosaccharomyees (the choice being
determined by other process parameters, mainly the downstream effluent
treatment system) is grown in 3 stages. The first two stages are designed for
aseptic growth. Propagation vessel III develops the inoculum using pasteurized
molasses solution as the medium. This vessel has a dual function. During
propagation, it serves for inoculum build-up. When the fermenter enters the
continuous production mode, Propagation Vessel III is used as an intermediate
wash tank. Propagation is carried out only to start up the process initially or
after very long shut-downs during which the fermenter is emptied.
• CO2 Scrubbing and Recovery:
The carbon-di-oxide produced during fermentation is scrubbed with water in
packed- bed scrubber, to recover alcohol. The water from the scrubber is
returned to the fermenter. About 1.0% of the total alcohol production is saved
by scrubbing the fermenter off gas. In plants where it is desired to recover
carbon-di-oxide, a part of the wash is drawn into a separate vessel and is
aerated there. This external aeration allows the recovery of CO2 uncontaminated
with air. More details of this system can be supplied on request.
• Fermentation Parameters (Typical):
The pH of the fermenter is maintained between 4.0 & 4.8 usually without addition
of any acid. The alcohol concentration is maintained between 7.0 & 7.5 % v/v,
unless a highly concentrate effluent is to be produced. To reduce the effluent
volume, the fermenter is operated at a very high dissolved solids level by
increasing the proportion of weak wash recycle. Under these conditions, alcohol
concentration is reduced to between 5.5 to 6.0% v/v.
Conversion of sugar to alcohol is instantaneous, and the residual sugar
concentration is maintained below 0.2 % w/w as glucose. This usually
corresponds to a residual reducing substances concentration of 2.0 to 2.5 %
w/w in wash.
All the nutrient elements necessary for yeast growth exist in adequate quantities
as impurities in molasses. Occasionally, Nitrogen may have to be supplemented.
Defoaming oil (DFO), say Turkey Red Oil is added to the fermenter by an
automated DFO dosing system, to control foaming. Usually no other additives are
required.
• Flexibility:
This process accords tremendous flexibility to the operator. Process conditions
and plant design can be varied to suit individual requirements of alcohol quality,
effluent concentration and characteristics. This unit can give spent wash
suitable for use in any effluent treatment process.
2. Distillation:
Clarified or de-yeasted wash flows by gravity to the propagation vessel No. III,
which during continuous production, operates as an intermediate wash tank.
From here, fermented wash is pumped to the wash preheater, which uses vapors
from the rectifying column to preheat wash. Further heating is done in an
exchange of heat with weak wash and spent wash (see flow sheet for primary
distillation). Preheated wash then enters the degasifying column of the
distillation section.
• Primary Distillation: The CO2 and the degasifying section help remove the CO2
and other non-condensable entrained in the wash. The wash column is first
column in the distillation section. It is also called the analyzer. Wash is boiled in
this column with steam either supplied as live steam from the boiler (after
pressure reduction and desuperheating) or from a reboiler which generates
steam by evaporating effluent wash.
Alcohol in wash vapourises and is carried, along with water vapor, to the top of
the wash column from where it goes to the rectification column. As wash travels
down the analyzer, it is progressively ‘stripped’ of its alcohol content. At a
point in the column, where the alcohol concentration is 0.5 to 1.0% v/v, a
portion of the wash is drawn off. This is called weak wash.
• Weak Wash Recycling :
Weak wash recycling of weak wash helps maintain the desired level of
dissolved solids in the fermenter, so that an adequately high osmotic pressure
is achieved. Osmotic pressure and the concentration of alcohol in the fermenter,
together keep off infection and minimize sugar losses. Weak wash recycling also
reduces the quantity of effluent spent wash and reduces the process water
requirement of the plant.
Spent wash is the wash from which all alcohol has been removed, this emerges
from the bottom of the wash column at about 105 deg C. Some of the heat is
recovered to preheat fermented wash entering the degasifying column.Spent wash
may also be passed through a forced circulation reboiler to generate vapors.
This concentrates the effluent and reduces the volume further.
Multi Pressure Vacuum Distillation:
After fermentation the next stage in the manufacture of alcohol is to separate
alcohol from fermented wash and to concentrate it to 95% alcohol called as
rectified spirit. For this purpose, distillation process is employed.
Distillation step consumes a considerable amount of energy and is also a
deciding factor in the quality of ENA produced. Hence, in line with the demand of
the industry, efforts have always been to minimize requirement of energy and to
improve the basic quality of alcohol produced. Ease of operation, reliability,
lower down time and flexibility of operations are other parameters considered
during the design.
Three basic types of plant are designed:
a) One is to produce primary quality of alcohol, usually referred to as 'Rectified
Spirit' (R.S.) from the fermented wash. Such plants are also referred to as
‘Primary distillation’ plants.
b) Second is to produce fine quality of spirit usually referred to as 'Extra Neutral
Alcohol' (ENA) starting from R.S. Such plants are also referred to as 'secondary
distillation' plants.
c) Third is to directly produce fine quality alcohol (ENA) from fermented wash.
Such plants are referred to as 'wash (mash) to ENA' plants, where the two steps
of primary and secondary distillation are combined. Such plants usually have
lower consumption of energy than two separate plants
Multi-pressure vacuum distillation system for production of Rectified Spirit
/ ENA consists of following distillation columns namely
1. Degasifying cum analyzer column – Operation under vacuum
2. Pre-rectification column – Operation under vacuum
3. Rectification cum Exhaust Column - Operated under pressure
4. Recovery column - Operated under atmospheric
5. Extractive distillation column – Operated under vacuum
6. Simmering column – Operated under atmospheric
Benefits of Pressure Vacuum Distillation: -
Following are the advantages of pressure vacuum distillation.
• Since the analyzer column operates under vacuum, the formation of byproducts
such as acetal may minimize there by improvement in quality of alcohol.
• Pre-rectification column ensure removal of sulfur compounds/mercaptans and
also reduces load of lower boiling volatile compounds passing on to Rectifier cum
exhaust column.
• The chances of scaling due to invert solubility of certain precipitating inorganic
salts are minimized in vacuum distillation.
• Vacuum distillation requires low steam consumption with re-boiler
Integrated Multi-products Concept: -
It is now possible to install a distillation system, which can produce different
products. In the proposed scheme; the production of rectified spirit have been
considered. This allows flexibility of operation and various products can be
manufactured depending on the market demand. This integrated multi-product
system involves less capital investment as compared to independent system.
In this type of system, switching over from one product to another is quite easy
and there is no chance of contamination of one product with another. The
system can work under multi-pressure principle with few columns operating
under vacuum and few under pressure/atmospheric.
3. Dehydration of Alcohol: Molecular Sieve:
The process drives the rectified feed though a bed of desiccant beds. To allow for
bed regeneration in continuous operation, twin beds are provided of which one
is in dehydration mode while the other is regenerating. Depending on feed
and product specifications, the dehydration-regeneration process releases the
adsorbed water together with contained ethanol, it is recycled back to
regeneration column for reprocessing.
The feed is pumped to regeneration column after preheating in feed
preheater. The overhead vapor of regeneration column is superheated to the
required operating temperature and circulated to sieve bed 1 assumed in the
description to be in dehydration mode. After passing though the desiccant, the
vapor is condensed, cooled and sent to storage.
A small portion of the product vapor is sent, under high vacuum, through bed
2, in regeneration mode, to prepare the desiccant for cycle changeover when bed 2
goes online. The regeneration operation forces the release of the moisture from
the desiccant, making the bed 2 ready for the next cycle. The recovered low
strength vapors are condensed and recycled back to the Regeneration column.
4. Evaporation for Spent wash Treatment
As per recent Environmental Protection Norms from Ministry of Environment
and Forests (MoEF), it is Corporates Responsibility to achieve Zero Discharge
in Inland Surface Water. For 60 KLPD distillery plant nearly about 600 M3/Day
spent wash will produced. Considering the large volume of spent and achieve Zero
liquid discharge plant operation following three stage process is proposed.
Multi pressure distillation – In this steam is utilized in direct way for heating.
Hence, spent wash quantity generated is less as compared to traditional
distillation technology. Integrated and Standalone Multi effect evaporation - The
spent wash evaporation technology is a multiple effect evaporator system in which
heat recovered from one effect is used to concentrate spent wash in second
effect evaporator with continuous recirculation of concentrated spent wash
within the system until desired concentration is obtained. This entire
concentration process is carried out under vacuum leading to less consumption
of steam and maximum concentration of spent wash with in less period of time.
This is the 3rd stage of effluent treatment wherein spent wash after integrated
evaporation is concentrated and used in incineration boiler.
5. Spent wash Incineration Technology:
After spent wash evaporation, concentrated spent wash with desired
concentration is obtained is feed to incineration type of boiler. The
concentrated spent wash generated after entire process of evaporation is then
sprayed in a furnace with auxiliary fuel such as coal and is then burnt in a
boiler.
6. Process Condensate Treatment and Recycle:
The condensate polishing unit is also envisaged to take care of spent lees, cooling
tower blow down, washing and process condensate from evaporation plant. After
treatment all the stream at CPU, treated condensate can be recycled to process
for dilution and as cooling tower make up and will achieve zero liquid discharge
(ZLD) Due to recycle of process condensate back to process, fresh water demand
can be reduced at large extent.

NSPL will generate about 40851 MT of molasses from expected / sustained cane
crushing of 54 Lacs MT / year, with minimum 4.7% molasses recovery. M olasses
will be sourced from parent sugar unit and group sugar factories. The fuel ethanol
yield from cane molasses will be at 270 lit/ton. The per day requirement of
molasses will be about 220 MT per day for 60 KLPD ethanol production per
day. The total requirement of molasses for the 270 days operation of the
proposed ethanol plant will be about 59400 MT (at maximum 95% utilization
level from 4th year onwards).
vii. Resource optimization/ recycling and reuse
Multi Pressure Distillation system has lower steam consumption as it is designed
for maximum heat integration to conserve energy.
Energy efficient Multi-Pressure Distillation system with a Steam Consumption
13.20 TPH of Total Spirit (depending on mode of operation).
Vacuum operation nearly eliminates scaling problem in Analyzer Column and
ensures better separation of impurities, which results into better quality product.
Well-engineered Plants with high efficiency trays to ensure elaborate separation
and removal of impurities ensuring superior quality of Extra Neutral Alcohol.
Analyzer Column with Hyper-stat Rh-Grid trays ensure high turbulence on tray,
this minimizes chances of scaling. Also, this special construction of trays and
access to each tray helps in easier cleaning column internals.
Condensers are designed with multiple passes to ensure high velocity and to
minimize scaling inside tubes.
Alcohol is well known as an industrial raw material for manufacture of a variety
of organic chemicals including pharmaceuticals, cosmetics, polymers etc. A large
demand is anticipated for alcohol as a fuel. Alcohol is an eco-friendly product and
is a substitute to the imported petroleum. Indeed fuel ethanol production has
been promoted for a variety of reasons as mentioned below,
It has less severe impact on the environment than conventional gasoline and
less dangerous to health. As oxygenates are compounds such as alcohols or
ethers which contain oxygen in their molecular structure. Oxygenated fuels tend
to give a more complete combustion of its carbon to carbon dioxide (rather than
monoxide) which leads to reduced air pollution from exhaust emissions. It
reduces the dependence on oil imports.
It helps to maintain rural economy.
Factory proposes zero liquid discharge method for waste water treatment.
Maximum waste water will be recycled back into the system.
Factory proposes to install Multiple Effect evaporator followed by Incineration
boiler. Advantages are as follows
Production of steam and power generation
Reduction in air pollution as compared to coal based boiler.
Reduction in water pollution and achieve zero discharge in inland surface water.
