PRE-FEASIBILITY REPORT
1.0 INTRODUCTION
Earlier, the assessment of the projects was done on Technical feasibility reports and Cost-Benefit-
Ratio which mainly considered financial & technical resources. But no consideration was given
to the environment protection in this evaluation and these flaws became apparent with continuous
deterioration of environment. Thus in order to have more realistic evaluation, and keeping in
view the deteriorating conditions, another dimension was added which is now called as
“Environmental Impact Assessment” (E.I.A.). This forms an integral part of the project and is
taken into account while appraising the project at different stages. Thus in the new
comprehensive approach all considerations like, Technical, Financial & Environmental are given
due weightage.
M/s UP Cooperative Sugar Factories Federation Limited is proposing a project of 3500 TCD
sugar plant expandable to 5000 TCD and 30 KLPD ENA/ethanol plant at Kisan Sahakari Chini
Mills Ltd., Sathiaon, Distt. Azamgarh, Uttar Pradesh.
As per EIA Notification dated 14th Sept., 2006 and amended from time to time, the proposed
project falls under Category “A”, Project or Activity 5(g) due to 30 KLPD molasses based plant.
They have to submit Form-I along with Pre-Feasibility Report and other relevant documents for
getting Environmental Clearance. This pre-feasibility report has, therefore, been prepared by the
consultant to assess the likely impact of the proposed on various factors which may be affected
with the implementation of the programme and to suggest remedial/precautionary measures, if
any.
2.0 PROFILE OF THE COMPANY & PROMOTORS.
The Kisan Sahakari Chini Mills Ltd. was installed during the year 1974-75 and was
commissioned during the season 1975-76 with a rated capacity of 1250 TCD to produce
plantation white sugar by the standard sulphitation process. The existing plant has become very
old. Since the plant is not in operation since 2006 and even before that no major repair or
modernization or expansion work was carried out in the plant the existing equipment has become
in efficient. Some of the important equipments were also provided from the existing plant to other
sugar factories.
The factory is located nearby district town of Azamgarh. The factory is around 12 kms. away
from Azamgarh City.
2.1 Need for installation of Sugar Plant Complex
The sugar industry in india is now well developed, competitive and moving with a fast pace in
technological development to produce sugar at a very competitive price in the world market.
Sugar factory alone is not a viable proposition unless it has value additions along with sugar
production in the form of production of ethanol and power export etc. Along with efficiency
improvement so that cost of production may be reduced.
The KSCM ltd., Sathiaon mill is keen to capitalize on these issues and wishes to exploit the
sugarcane availability by explosion and modernization of its existing sugar plant to produce
additional quantity of good quality sugar at lower cost of production for improving financial
health of the sugar mill. The sugarmill also proposes to produce additional power for export to
state grid through Co-generation along with a modern and efficient distillery.

3.0 BASELINE ENVIRONMENTAL SETTING
3.1 The State
Uttar Pradesh (UP), is a state located in northern India. It was created on 1 April 1937 as
the United Provinces, and was renamed Uttar Pradesh in 1950. Lucknow is the administrative
capital of Uttar Pradesh. Ghaziabad, Kanpur, Moradabad, Aligarh, and Varanasi are known
for their industrial importance in the state. On 9 November 2000, a new state, Uttarakhand, was
carved out from the Himalayan hill region of Uttar Pradesh.
The state is bordered by Rajasthan to the west, Haryana and Delhi to the
northwest, Uttarakhand and the country of Nepal to the north, Bihar to the east, Jharkhand to
the southeast, Chhattisgarh to the south and Madhya to the southwest. It covers 93,933 square
miles (243,290 km2), equal to 6.88% of the total area of India, and is the fourth largest Indian
state by area. With over 200 million inhabitants in 2011, it is the most in the country as well as
the most populous country subdivision in the world. Hindi is the official and most widely
spoken language in its 75 districts. Uttar Pradesh is the fourth largest Indian state by
economy, with a GDP of 7080 billion (US$110 billion). Agriculture and service industries are
the largest parts of the state's economy. The service sector comprises travel and tourism, hotel
industry, real estate, insurance and financial consultancies.
Uttar Pradesh was home to powerful empires of ancient and medieval India,
including Magadha, Nanda, Mauryan, Sunga, Kushan, Gupta, Gurjara, Rashtrakuta, Pala a
nd Mughal which many say was improved by the Nawabs of Awadh. The two major rivers of
the state, the Ganga and Yamuna, join at Allahabad and then flow as the Ganga further east.
The state has several historical, natural, and religious tourist
destinations,suchasthe TajMahal, Varanasi, Piprahwa, Kaushambi, Kanpur, Ballia, Shravast
i, Kushinagar, Lucknow, Chitrakoot, Jhansi, Allahabad, Budaun, Meerut and Mathura.
3.2 District Azamgarh
The district is named after its headquarters town, Azamgarh. Azam, son of Vikramajit, founded
the town in 1665. Vikramajit a descendant of Gautam Rajputs of Mehnagar in pargana
Nizamabad had embraced the faith of Islam. He had two sons, namely, Azam and Azmat. It is
also known as land of the sage Durvasa whose ashram was located in Phulpur tehsil, near the
confluence of Tons and Majhuee River, 6 kilometres north from the Phulpur tehsil headquarters.
Azamgarh district has an area of 4,054 square kilometres (1,565 sq mi). The district lies between
the Ganges and the Ghagahara Azamgarh district is surrounded by the districts of Mau in the east,
Gorakhpur in the north, Deoria in the south-east, Jaunpur in the south-west, Sultanpur in the west
and Ambedkar Nagar in the north-west.
Azamgarh district is further divided into 7 tehsils, and 22 development blocks. There are 4,106
villages (3,792 inhabited and 314 uninhabited) in the district.

4.3 MANUFACTURING PROCESS DESCRIPTION :
Sugar molasses in chosen as the raw material for the production of various grades of alcohol
proposed to be produced, in as much as the distillery is a captive unit of Kisan Sahakari Chini
Mills Ltd., Sathiaon, Azamgarh, U.P. There are two grades of alcohol to be manufactured
primarily. These are Extra natural Alcohol (ENA) and fuel grade absolute alcohol (AA). Based on
the technology review, it is proposed to use modified batch fermentation followed by the multi-
pressure distillation for the production of ENA. Absolute alcohol is proposed to be manufactured
from R.S. drawn from intermediate column, based on molecular sieve distillation process. Impure
spirit cut through produced is blended with R.S. for A.A production subject to level of Aldehyde
impurity.
Fermentation:
Yeast is developed form fresh slant in laboratory flask and the culture thus obtained is further
propagetd in three stages. Yeast propagation vessels where sterilized dilute molasses are taken
and operate in series but in batch mode. When enough biomass strength is developed , it is
pitched into prefermenters from thereon to fermenters. The yeast vessels are fitted with jacket
for sterilizing and cooling the medium in situ. Sterile air is supplied to those vessels through
non-lubricated, oil free compressor and the sterilization system comprising a series of fine filters
followed by HEPA filters. Molasses form the Molasses tank in the yard are pumped by transfer
pump into molasses day tank and thereon to molasses receiving tank and then on to tipper type
molasses weighing system and weighed molasses feed tank from where molasses feed pump
pumps it to yeast vessels (when necessary) or to fermenter through a static mixer type molasses
diluter.
There are four fermenter each of 240 kilo liter capacity. The feeding of bio mass and dilute broth
are periodic and regulated so that the sugar content and yeast population are regulated to give
best of efficiency and activity. The exothermic heat of fermentation is extracted by circulating
the fermenter contents through wort collers (E02 & E03). Temperature in the fermenters is to be
maintained at <340C. Carbon Di-oxide evolved during fermentation is vented out through
scrubber to recover entrained alcohol vapors. The final fermented wash is transferred by wash
transfer pump to wash holding tank from where wash feed pump pumps the same to distillation
plant. It may be noticed that there is no sludge separation conceived. The yeast sludge is rejected
at the distillation plant. Part of spent wash from a selected tray in the analyzer column of
distillation section is returned to fermenters after cooling the same to as near to ambient temp as
possible as a measure of reducing the water consumption and high TDS in spent wash. Anti
foam oil is added from whenever necessary when the level in the fermenter rises beyond a limit
due to foaming because of run away fermentation rate. Process water is taken into scrubber and
from there to scrubber water tank. All process water in the fermentation section is supplied by
water supply pump from this tank.
Distillation
While, fermentation section is the heart of productivity, distillation section is the heart of quality
production. This section, as mentioned earlier, is the most energy consuming and hence is
provided with utmost automation and is designed for maximum energy conservation. The system
is designed to give Extra Neutral Alcohol with a maximum of steam consumption quality
rectified spirit. Impure spirit cut may be mixed back with rectified spirit as feed for production
of absolute alcohol or blended with RS to make SDS.
Multi Pressure Vacuum Distillation
The vacuum distillation has many advantages over conventional atmospheric distillation plants
like lower energy requirement, better quality products and less scaling on the distillation trays
due to sludge. The vacumm distillation produces ethanol of international quality standards and
there is a lot of demand of ethanol from the vacuum distillation process. Alcohol quality, which
is produced form this latest technology, meets to most of the international quality standard like
US, British and Japanese standards.
The vacuum distillation approximately requires 50 % less steam as compared to conventional
old distillation technologies. The vacuum distillation consists of distillation columns with high
efficiency column trays, condensers, Reboilers, Vacuum Pumps and Reflux Pumps.
In this vacuum distillation, alcohol is separated and concentrated using fractional distillation.
This is based on difference in boiling points of involved compounds in mixture. There are eight
distillation columns in the system. These are Primary Column, Degasser Column, Pre-Rectified
Column, Hydro-extractive distillation column, rectifier column, refining column, de-recovery
column and De-Aldehyde column.
Primary cum degasser column
Primary column (Analyzer Column) is operated under vacumm and it is heated using the top
vapors of the Rectifier Column. The Vacuum operation of the Primary column decreases the
overall energy requirement of the column. Due to vacuum, scaling is also reduced in this column
and plant can be operated for long time smoothly.
The fermented wash is pre-heated using a beer heater and followed by a plate heat exchanger,
then it is fed at the top of the Degasser Column. The pre heating of mass in two stages recovers
energy and saves steam required for the distillation.
Degassser column separates the impurities on the basis of boiling point. These impurities are
sent to De-Aldehyde column.
The semi-solid waste in fermented wash is reached at the bottom of Primary column. This semi-
solid waste is called as spent wash & sent to Effluent treatment plant for further separation.
Primary Rectifier Column
Primary rectifier column is derived on steam indirectly with the help of one reboiler. The
column gets feed from analyzer column & de-Aldehyde column. This column is operated under
vacuum condition to reduce the steam consumption & better quality. Heavy and light fusel oil
are separated from this column and fed to De-fuel oil column.
Impure spirit is also separated form the condenser of this column. Column top vapors are
condensed in one beer heater and remaining in condensers.
Alcohol is concentrated in this column & spent water (spent less) is separated from the bottom
of the column. Rectified spirit is separated from this column is fed to Hydro extractive column
Hydro extractive column
This column is derived on steam with the help of one reboiler. Rectified spirit which is separated
from Primary Rectified Column is fed to this column. Extraction process takes place in this
column. So, water is added in this column. Impurities which are soluble in water are taken out
from the bottom of this column. Esters in the form of ethyl acetate are also separated from this
column and sent to Defusel Column. Bottom stream of this column is fed to rectifier column.
Top vapors of this column drives the refining Column. Alcohol condensed in the reboiler of
reeing column, sent back return to Hydro Column as Reflux.
Rectifier Column
The bottom of hydro-extractive column is transferred to Rectifier column as feed. The impurities
which are not separated in Pre-rectifier Column are separated in this column.
Stream is given to this column indirectly. One column is provided to it. Heavy & Light fusel oil
is separated from this column and sends to De-fusel Oil Column. Top vapors of this column
drives to Analyzer Column. Impure Spirit is separated from this column and fed to De-Aldehyde
Column.
Separated export quality rectified spirit is sent to Refining Column. The waste water is separated
from rectifier column is pumped out from bottom of the column. 50 % of spent lee is recycled to
hrdro column to reduce the water consumption.
Recovery Column
All fusel oil and esters impurities are fed to this column. Heavy Fusel oil and light fusel oil is
drawn out from the column & concentrated in decanters. Water is also used for washing of
fusel oil & to recover the alcohol. When Fusel oil is get concentrate in decanter. Water is also
used for washing of fusel oil and to recover the alcohol. When fusel oil is get concentrate in
decanter, fusel oil transferred to fusel oil storage.
Refining Column
All tray of this column are made of De-Oxy Copper. The main purpose of this column is to
remove the methanol from Extra Neutral Alcohol. Technical alcohol is separated from its
condenser and sent to storage after cooling.
Extra Neutral Alcohol is collected at the bottom of this column & sent to receiver after passing it
from cooler.
Fuel Grade Ethanol
Absolute alcohol is manufactured by dehydration of Rectified Spirit. The process adopted here is
based on Pressure Swing Adsorption (PSA) system using Molecular Sieves.
Rectified spirit, after preheating by waste hot streams, is vaporized and superheated by using
medium pressure steam at 6 kg/cm2 g pressure. Hot Vapours at 2 kg/cm2 g pressure and 130°C
temperature pass through PSA column where the water vapours are retained while water free
alcohol is released as vapours. These vapours are retained while water free alcohol is released as
vapours. These vapors are condensed and collected as Absolute Alcohol. When the molecular
sieve bed is saturate with water the alcohol vapours are shifted to the other tower and the first
tower is taken for regeneration. Regeneration is done first by pressure releasing and creating
vacuum and then by elutriating with dehydrated alcohol vapours from the tower in dehydration
operation. The alcohol water vapours are condensed in and the vent vapours are recovered
through a water scrubber. Vacuum can be created by vacuum pump or by Eductor. Product is
cooled and transferred to absolute alcohol receiving tank and then on to storage tanks.

provide the data in respect of rainfall. However, it has been informed that the rainfall in
operational area is good
(iii) Irrigation
The cane growers irrigate the sugarcane crop through tube wells and pumping sets. Also, there is
huge potential for utilizing the underground water as the water level is only between 20 to 30
feet depth with the good quality of water. From the point of view of sugarcane cultivation, year
round irrigation is most essential. In the sugar factory zone, the cane growers apply about 10-12
irrigations to sugarcane crop. For maximization of yield upto 70 tonnes/hectare irrigation to
sugarcane crop is most essential.
(ii) Topography
The topography of the area is flat.

to provide employment opportunities.
(c) Green Belt
Greenbelt will be developed in 33% of the total area of the proposed project.
(d) Social Infrastructure
Proposed project will result in growth of the surrounding areas by increased direct and
indirect employment opportunities in the region including ancillary development and
supporting infrastructure.
(e) Connectivity
The project is well connected with Rail and Road.
(f) Industrial Waste management
The proposed plant would be based on “ZERO EFFLUENT DISCHARGE”.
6.0 REHABILITATION AND RESETTLEMENT (R & R) PLAN
No Rehabilitation and Resettlement plan is applicable because there are no Rehabilitation &
Resettlement of the people.
7.0 PROJECT SCHEDULE AND COST ESTIMATES
The project will start only after obtaining Environmental Clearance and all other required
clearance and will complete after two years of commencement.
The Capital Cost of the project is Rs. 33,800 lakhs.
8.0 WASTE MANAGEMENT
8.1 Liquid Effluent:
Excepting for the major and most harmful effluent (Spent wash) from the analyzer column and
fermenter sludge, other effluent are quite small and do not need any specific treatment. The purge
from cooling tower will probably small and do not need any specific treatment. The purge from
cooling tower will probably have a maximum of 2000 ppm of dissolved solids. Floor washings
will have some dissolved solids and some gritty material. Spent less is generally pure and hence
most of it is recirculated to the process. Boiler blow down will have 3000 ppm of dissolved solids
and can go to normal drainage system. Hence, the effluent treatment system for the spent wash
and fermentation sludge will be as follow:
Spent Less Treatment:
The proposed distillery produces about 413 m3 of spent wash per day at the production of 46000
LPD of rectified spirit and has the characteristics as shown in table below:

Colour Dark Brown
There are basically two types of treatment given to this effluent:
(1) Biological Treatment
(2) Concentration and Incineration
In view of capital investment being very high and also due to technical difficulties of operating
the system, the incineration method is not considered in the present case. It is proposed to
treat the effluent only by biological treatment.
The spent wash form Analyzer column in the distillation section after recovery of alcohol form
fermented wash, after exchanging heat with some cold streams, is pumped to spent wash clarifier.
The settled solids are pumped to composting plant. Clarified spent wash is transferred to
equalization lagoon in the bio-methanation plant. From where it is fed to the bio-reactor which is
a continuous Stirred Tank Reactor type anaerobic reactor and operates with mesophylic bacterial
reaction.
8.2 Air Pollution:
Air pollutant from a distillery plant are basically from boiler. These are particulates and acidic
constituents in the flue coming from fuel. Fuels used are bio gas and coal. The coal consumption
is 1.3 T/hr and hence the particulate emissions are controlled through cyclone separator on the
flue path prior to going to chimney. This is already provided in boiler configuration. Ash is
collected and disposed off as land fill or can also be sold to brick manufacturers.
8.3 Solid Waste:
Boiler ash collected and disposed off as land fill or can also be sold to brick manufacturers. The
other solid wastes expected from the unit are containers, empty drums which are returned to the
product seller or sold to authorize buyers after detoxification.
8.4 Noise Pollution Control:
There is no danger of noise pollution from plant. The green belt will (plantation of dense trees
across the boundary) help in reducing noise levels in proposed plant as a result of attenuation of
noise generated due to plant operations, and transportation.
Earmuffs would be used while running the equipments of the plant.
D.G sets are provided with acoustic to control the noise level within the
prescribed limit.
A high standard of maintenance will be practiced for plant machinery and
equipments, which helps to avert potential noise problems.
9.0 GREEN BELT DEVELOPMENT/ PLANTATION
Green belt development in and around the project site helps in to attenuate the pollution level.
About 33% (8 Acres) land area of project will be developed as green belt and it will be
maintained in future also. Green belt will be developed as per Central Pollution Control Board
(CPCB) Norms. The Avenue plantation will give priority to native species, and the periphery will
be devoted to generation of green belt area.
Green belt development in and around the project site will help in to attenuate
the pollution level.
Native species will be given priority for Avenue plantation.
The periphery will be devoted to generation of green belt area.
10.0 CSR Activities
Proposed project will result in growth of the surrounding areas by increased direct and indirect
employment opportunities in the region including ancillary development and supporting
infrastructure. Special emphasis on Financial and Social benefits will be given to the local people
including tribal population, if any, in the area. Development of social amenities will be in the
form of medical facilities, education to underprivileged and creation of self help groups.
No adverse effect on environment is envisaged as proper mitigation measures will be taken up
for the same.
