1.0 PROJECT DESCRIPTION

1.1 Introduction

Although India is the largest producer of sugarcane and sugar, the sugar

factories in India are facing problems due to the mismatch between sugar

cane price and sugar price. Sugar factories are not viable if they produce

sugar alone. It is necessary to develop the factory into an integrated complex

and use the valuable byproducts more beneficially.

Molasses is one of the important by product of the sugar industry. The profits

earned by the conversion of molasses to alcohol will be higher that that of

the value realized by sale of molasses. There is a good demand for alcohol in

the country, as production and consumption of alcohol are not quite

balanced.

The target of alcohol demand as projected in the perspective plan for

chemical industry, prepared by the Govt. of India, Ministry of Industry, Dept.

of chemical and petrochemicals is around 2400 million liters per annum. It is

with this view that M/s. Ponni Sugars (Erode) Limited has proposed to set up

a green field distillery in Paramathi Taluk, Namakkal District. M/s. Ponni

Sugars (Erode) Limited proposed to have one distillery with an installed

capacity of 60,000 litres/Day of Rectified Spirit (RS) / Extra Neutral Alcohol

(ENA) / Anhydrous Alcohol at Kunnamalai. The distillery utilizes molasses

captively from the sugar factory as the main raw material. In order to add

value to molasses, it is proposed to set up a green field distillery to convert

all the available molasses to a mix of alcohol products.

The proposed new distillery will have the flexibility to produce Rectified Spirit,

Extra neutral alcohol and Anhydrous Alcohol based on the market

requirement. The plant will incorporate multi-pressure distillation over

conventional steam distillation for better energy efficiency and consistent

good quality of the product.

1. Fermentation Section

Screened molasses from bulk storage is transferred to molasses receiving

tank and molasses is weighed. Weighed molasses is distributed to cell mass

propagation, fermentation and yeast activation section.

Yeast is grown in laboratory during plant start up. Yeast propagation section

comprises of molasses diluter and hygienically engineered yeast vessels

equipped with heating, cooling and air sparging facility. Dilute molasses

media are prepared in yeast vessel by recirculating media through molasses

diluter. Laboratory propagated cell mass is scaled up in series of yeast

vessels.

Sterile air is sparged in pasteurized and cooled dilute molasses medium for

optimum growth of yeast. Temperature is maintained at 30-32°C by

recirculation cooling water through jacket of yeast vessels. Cell mass from

Yeast vessel is transferred to Prefermentors to build up cell mass required for

fermentation transferred by cell mass transfer pump.

At steady state, activated cell mass from Prefermentors is transferred in

batch to fermentors. Feed (Molasses), process water is also added in batch to

fermentor

As ethanol fermentation is exothermic process, optimum temperature

required for yeast activity is maintained by forced recirculation through

fermentor wash coolers. Efficient mixers are provided in fermentors for better

mass transfer. Fermented wash from Fermentor is sent to wash holding tank

and pumped to distillation section.

2. Distillation SectionA) Wash to RS Mode: -Following columns will be under operation

i. Analyser Column (Vacuum)

ii. Degasifying Column (Vacuum)

iii. Rectifier cum Exhaust Column (Pressure)

iv. Recovery Column (Atmospheric)

Steam Consumption: 2.2 kg/lit of Total Spirit

Pre-heated fermented wash will be fed to Degasifying column. Fermented

wash is stripped off alcohol by ascending vapours in Analyser column.

Rectifier vapours provide energy to Analyser column through a

Thermosyphon reboiler. Vapours of Degasifying column are condensed and

taken to Recovery Feed Tank. Analyser vapours are condensed in the Falling

Film Evaporators in the Integrated Evaporation Section. The condensed

Analyser vapours are taken to Rectifier Feed Tank. Rectifier column, which

operates under pressure, concentrates the condensate of Analyser column to

95% v/v concentration. Condensing steam provides energy to rectifier

column through a vertical Thermosyphon reboiler. Fusel Oil Draws are taken

from appropriate trays and fed to Recovery Column. Recovery Column

concentrates the fusel oil streams and Degasifying condensate to 95% v/v

concentration. An impure spirit cut of about 2-3% of total spirit production is

taken out from the top of the recovery column. Rectified Spirit draw of 95%

v/v is taken out from the upper trays of Rectifier Column.

(B) Wash to ENA Mode: -

Following Columns will be under operation

1. Analyser Column (Vacuum)

2. Degasifying Column (Vacuum)

3. Pre-Rectifier cum Exhaust Column (Pressure)

4. Extractive Distillation Column (Vacuum)

5. Rectifier cum Exhaust Column (Pressure)

6. Recovery Column (Atmospheric)

7. Simmering Column (Atmospheric)

7


Steam Consumption: 3.3-3.4 kg/lit of Total Spirit

Pre-heated fermented wash will be fed to Degasifying column. Fermented

wash is stripped off alcohol by ascending vapours in Analyser column.

Rectifier vapours provide energy to Analyser column through a

Thermosyphon reboiler. Vapours of Degasifying column are condensed and

taken to Recovery Feed Tank. Analyser vapours are condensed in the Falling

Film Evaporators in the Integrated Evaporation Section. The condensed

Analyser vapours are taken to Pre-Rectifier Feed Tank. Analyser Condensate

is concentrated in Pre-Rectifier column, which operates under pressure.

Condensing steam provides energy to pre-rectifier column through a vertical

Thermosyphon reboiler. A Technical Alcohol cut of about 1-2% of total spirit

is taken from the Pre-Rectifier column.

Concentrated alcohol draw from Pre-Rectifier column is fed to Extractive

distillation column for purification. Dilution water in the ratio of 1:9 is added

in this column for concentrating higher alcohol at the top. Top of this column

is condensed in its condensers and fed to recovery feed tank while bottoms

are fed to Rectifier cum Exhaust Column for concentration. Rectifier Column

operates under pressure and condensing steam provides energy to this

column through a vertical Thermosyphon reboiler. Technical Alcohol cut is

taken out from the top of this column while ENA draw is taken out from

appropriate upper trays and fed to Simmering Column after cooling. Fusel Oil

build up is avoided by taking fusel oil draws from appropriate trays.

These fusel oils along with the condensate of Degasifying & Extractive

Distillation columns are fed to recovery column for concentration. A technical

alcohol cut is taken out from the top of this column.

Simmering Column is operated under high reflux for better separation of

methanol and di-acetyls. Final ENA product draw is taken from the bottom of

this column.

3. Dehydration Section

The process drives the rectified spirit feed from rectifier column through a

bed of desiccant beads. Twin beds are provided to allow for bead

regeneration in continues operation. One bed is in dehydration mode while

the other is regenerating. Depending on feed and product specifications,

dehydration-regeneration exchange takes place approximately every few

minutes. As the regeneration process releases adsorbed water together with

contained ethanol, it is recycled back to the vaporizing column for

reprocessing.

The feed is pumped to vaporizing column, overhead vapor of which is

superheated to required operating temperature and circulated to sieve bed 1

assumed in the description to be in dehydration mode. After passing through

the desiccant, the vapor is condensed, cooled and sent to product 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 release of moisture from the desiccant,

making the bed 2 ready for next cycle. The recovered low concentration

vapors are condensed and recycled back to the vaporizing column.

The stream (lees) from the bottom of the vaporizing column, containing a

maximum of 2000 PPM of ethanol, is pumped to battery limits.

4. Evaporation Section

The Spent Wash at the concentration of 17-18% w/w solids is fed to the

First effect of the Falling film Evaporator through specially designed

Distribution nozzles which ensures the thorough wetting of the tubes and

thereby ensures that there are no dry surfaces created on the inside tube

surface. The partially concentrated spent wash is then pumped to the second

effect from where the concentrated product is drawn out at the desired

9


concentration depending upon the mode of operation. The Analyser vapours

shall be supplied to the first effect shell side. Vapours generated in the first

effect are used as a heating medium in the second effect and so on. The

system operates under pressure & vacuum. Water-ring vacuum pumps are

used to maintain a desired vacuum in all the effects. Cooling water from

cooling tower is used in the surface condensers for condensing the vapours

from the last effect. The analyzer vapour condensate will be collected in a

tank and fed to Pre Rectifier column in Distillation Section.

The Spent wash is fed from an inlet nozzle into the lower section by a

specially designed distributor plate. The liquid along with solid bits is then

distributed through the tubes. The solid bits are maintained in a fluidized

state. The solids impart a gentle scouring effect on the inside of the tube

walls while moving upward through the tubes. While keeping the tubes clean,

this also enhances the heat transfer coefficient without damage to the tube

material.

At the top of the channel, a disengagement zone is provided which separates

the bits from the exiting liquid. The wire bits are then recirculated to the inlet

chamber through down comer tubes. The Spent wash is finally taken out at

58-60% concentration from the Finisher. The low-pressure live steam shall

be supplied to the first effect shell side. Vapors generated in the first effect

are used as a heating medium in the second effect and so on which effects in

reduction in overall steam consumption of the system.

The system operates under pressure & vacuum. Water-ring vacuum pumps

are used to maintain a desired vacuum in all the effects. Cooling water from

cooling tower is used in the surface condenser for condensing the vapors

from the last effect.

iv. Reject characteristics:


1. Color Colorless

2. pH 6.5

3. COD <10000 mg/lit

4. BOD <5000 mg/lit


The proposed system is based on cross-flow membrane filtration technique

and is designed for removal of organic acids from the spent distilled stream

like evaporation condensate/spent lees of a bio-ethanol complex.

The condensate / Spent lees treated by such system can be reused back in to

the bio-ethanol manufacturing process as process water or cooling water

make-up thereby reducing the requirement of fresh water as well as solving

the problem of waste disposal to a great extent.

The system is based on following principle operations:

1) Cooling & Neutralization

2) Membrane filtration of the neutralized stream to remove volatile acids

3) Recycle of treated streams back to process

System typically recovers 85 to 90 % of the condensate / lees as clean

reusable water and has about 10 to 15 % reject. (These figures are based on

input levels of organic acid which are mentioned in below section).

ENVIRONMENTAL MANAGEMENT PLAN

7.1 Air Pollution ManagementThe minimum quantity of CO2 emitted from the fermentor will be connected 15m height and 0.6m dia of stack with CO2 scrubber and the clean CO2 air alone will be vented to atmosphere. For Boiler (21 MT/hr) 50 m height of stack with bag filter will be provided. For D.G.Set 18m height and 0.2m dia of stack will be provided. Hence in this project, there will not be any chance of air Pollution. For better atmosphere the proper ventilation will be provided in the structure.

7.2 Wastewater management

The wastewater from the domestic usages (3.2 KLD) will be sent directly to

the septic tank of size 3.0 x 2.0 x 2.0 m followed by the dispersion trench of

size 3.0 x 2.0 x 3.0 m . The spent wash water from the process 632 KLD will

be concentrated in multiple effect evaporator followed by incineration is

specially designed boilers.

By this way, the management proposes to achieve zero discharge system to

have a better environment not only in the factory premises and also to the

surrounding environment.

PROCESS DESCRIPTION OF EVAPORATION SYSTEM

Five Effect Falling Film Evaporator

Flow = inlet – E1 – E2 – E3 – E4 - E5

The above flow pattern is specially designed for utilization of available

energy. High wetting rates are provided in falling film bodies. This will

reduce scaling and the offline CIP frequency/downtime of evaporator.

The spent wash from distillery from storage is fed to falling film Evaporator

system, where it is concentrated from 17% to 25% solids. The analyzer

column vapors and exhaust steam from Turbine are used as heating media.

All the Effects are falling film type with vapour separators.

The feed from feed tank will be introduced into the effect 1. The vapours

from analyzer column are used as heating media in Effect 1 and recovered in

the form of condensate. Partially concentrated feed is then transferred to

19


Effect 2 and subsequently to effect 3. The vapour from Effect 1, are given to

Effect 2 as heating media. Evaporated vapours from effect 2 are used as

heating media in Effect 3 and so on. Finally the vapours separated in VS 3

are condensed in a Plate type surface condenser.

The partially concentrated feed flows from E1 to E2, E2 to E3 and further up

to E5, by means of transfer cum recycle pumps. Final concentration is

achieved in Effect 5. Level control loops are provided for all effects to ensure

trouble free operation.

INCINERATION OF CONCENTRATED SPENT WASH

The concentrated spent wash of around 55 brix from the concentration plant

is then pumped in to the specially designed boiler for incineration along with

pulverised coal as supplement fuel. The concentrated spent wash with above

composition and calorific value is burnt to generate steam at designed

pressure and temperature. This steam is then taken into turbine for

generation of power and the exhaust steam is utilized for concentration and

other process requirements.

The flue gas from combustion process is vented out after removal of

suspended particulate matter in specially made bag filters and sulfur-dioxide

in scrubbers. The ash collected from the process rich in potash can be sold

for fertilizer application and used in brick / cement blocks manufacturing.

7.3 Solid Waste Management

Sl.No

.Solid Wastes Quantity Method of Disposal

1. Settled Yeast Sludge

10.5 t/Day Burnt in boiler along with spent wash after concentration.

2. The Potash rich ash from boiler

44 t/Day collected and dispose 1. To local farmers as a fertilizer (potash rich).2.To Near by Brick manufacturing units

20


7.4 Noise Level

As per the observations, the noise level in the buffer zone is found to be very

low.

7.5 Land Degradation

Since, the small quantity of wastewater will be generated from domestic

usages, the chances of contamination of soil will be nil. The vacant area in

the industry will be used for tree plantation to improve the surrounding

environment of the industry.

7.6 Greenbelt Plan

Greenbelt is developed inside the factory premises covering a total area of

about 1.51 hectares The unit will also develop the nearby area around the

industry for greenbelt. The inter-spaces are laid with shrubs. The inter-space

between trees planted is about 5m. It is proposed to double the tree density

in future.
