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

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

Page 10: PRE-FEASIBILITYREPORT FOR 3500 TCD sugar …environmentclearance.nic.in/writereaddata/Online/TOR/0_0_13_Apr...PRE-FEASIBILITYREPORT FOR 3500 TCD sugar plant expandable to ... is proposing

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.

Page 11: PRE-FEASIBILITYREPORT FOR 3500 TCD sugar …environmentclearance.nic.in/writereaddata/Online/TOR/0_0_13_Apr...PRE-FEASIBILITYREPORT FOR 3500 TCD sugar plant expandable to ... is proposing

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

Page 12: PRE-FEASIBILITYREPORT FOR 3500 TCD sugar …environmentclearance.nic.in/writereaddata/Online/TOR/0_0_13_Apr...PRE-FEASIBILITYREPORT FOR 3500 TCD sugar plant expandable to ... is proposing

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.

5.0 SITE ANALYSIS

(i) Connectivity

The Sugar mill is located at Sathiaon which is about 12 kms. away from Azamgarh District. The

nearest railway station which is adjoining to the sugar mill only at half km away from the mill.

(ii) Rainfall and Temperature:

The minimum temperature in operational area comes down to 4.0 degree centigrade during winter

in January and it increases upto 45.00C in the month of June. The officials of sugar unit did not

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.

(v) Social Infrastructure available

There are primary schools, dispensaries, small hospitals, places of worship in nearby area of the

project site.

(vi)Proposed infrastructure

(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:

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.

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.

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.
