Annexure 1: Production and Manufacturing Details

(A) Distillery –

Baramati Agro Ltd. has existing 60 KLPD distillery. Now they propose to expand by 100 KLPD

capacity, thus total capacity of the distillery after expansion will be 60 + 100 = 160 KLPD. The

peculiarities of manufacturing process are as follows: This is a simple three step process namely

molasses preparation, fermentation and distillation. The standard flow sheet as will be adopted

can be given as:

Fig. 1: Distillery Process

For the sake of eco-friendly considerations continuous fermentation and multi- pressure

distillation will be practiced. The CO2 will be scrubbed in water and the water that entraps

escaping alcohol fumes will be recycled for molasses preparation.

(B) Sugar Unit –

Baramati Agro Ltd. has existing 4500 TCD cane crushing capacity. Now they propose to expand

by 7500 TCD capacity, thus total cane crushing capacity of the sugar factory after expansion will

be 4500 + 7500 = 12000 TCD.

The major unit operations are shown in figure these are

1. Extraction of juice

2. Clarification

3. Evaporation

4. Crystallization

5. Centrifugation

1. Extraction of Juice

The sugarcane is passed through devices like knives for cutting the stalks in to chips before being

subjected to crushing in a milling tandem comprising 4 to 6 three roller mills. Fine preparation

with its impact on final extraction, is receiving special attention & shredders & particularly the

fibrizsers are gaining popularity. The mills are of modern design, being equipped with turbine

drive, special feeding devices, efficient compound imbibitions system etc. In the best milling

practice, more than 95% of the sugar in the cane goes into the juice, this percentage being called

the sucrose extraction or more simply the extraction.

A fibrous residue called bagasse; with a low sucrose content is produced about 25 to 30 % of

cane, which contains 45 to 55% moisture.

Fig. 2: Sugar Manufacturing Process

2. Clarification

The dark-green juice from the mills is acidic (pH 4.5) & turbid, called raw juice or mixed juice.

The mixed juice after being heated to 65 to 75 0 C is treated with phosphoric acid, sulphur

dioxide & milk of lime for removal of impurities in suspension in a continuously working

apparatus. The treated juice on boiling fed to continuous clarifier from which the clear juice is

decanted while the settled impurities known as mud is sent to the field as fertilizer. The clear

juice goes to the evaporators without further treatment.

3. Evaporation

The clarified juice contains about 85 % water. About 75% of this water is evaporated in vaccum

multiple effects consisting of a succeeding (generally four) of vaccum boiling cells arranged in

series so that each succeeding body has higher vaccum. The vapours from the final body go to

condenser. The syrup leaves the last body continuously with about 60% solids & 40% water

4. Crystallization

The syrup is again treated with sulphur dioxide before being sent to the pan station for

crystallization of sugar. Crystallization takes place in single-effect vaccum pans, where the

sysrup is evaporated until saturated with sugar. AT this point ‘seed grain’ is added to serve as a

nucleus for the sugar crystals & more syrup is added as water evaporates. The growth of the

crystals continues until the pan is full. Given a skilled sugar boiler(or adequate instrumentation)

the original crystals can be grown without the formation of additional crystals, so that when the

pan is just full, the crystals are all of desired size & the crystal & syrup form a dense mass

koown as ‘massecuite’. The ‘strike’ is then discharged through a foot valve into a crystallizer.

5. Centrifugation

The massecuite from crystallizer is drawn in to revolving machines called centrifuges. The

perforated lining retains the sugar crystals, which may be washed with water if desired. The

mother liquor ‘molasses’ passes through the lining because of the centrifugal force exerted &

after the sugar is ‘Purged’ it is cut down leaving the centrifuge ready for another charge of

massecuite . Continuous centrifuges may purge low grades. The mother liquor separated from

commercial sugar is again sent to pan for boiling and recrystallization. Three stages of

recrystallization are adopted to ensure maximum recovery of sugar in crystal form. The final

molasses is sent out the factory as waste being unsuitable for recovery of sugar under

commercial condition from economical point of view.

(C) Co-Gen Power Plant- –

Baramati Agro Ltd. has existing 20 MW co-gen plant. Now they propose to expand by 50 MW

capacity, thus total capacity of the Cogeneration Power plant after expansion will be 20 + 50 =

70 MW. (This also includes turbo set of 10 MW dedicated for the distillery).

The peculiarities of manufacturing process are as follows: This is a simple three step process

namely Water preparation, Steam Generation and Power Generation. The standard flow sheet as

will be adopted can be given as

a. For Sugar and Co-gen

From Sugar and Co-gen unit, two types of waste water comes out: i) Effluent generated

from sugar process and ii) Condensate water.

For Effluent generated from sugar process, ETP is provided. The flow chart of sugar

ETP is provided below.

Fig. 4: Sugar ETP Flow Sheet

The effluent is first treated in anaerobic digester and then sent to degasser to remove

gases. Further it is sent to Lamella Clarifier and then to first Aeration Tank. Output of

Aeration tank is sent to Clarifier-I and then to second Aeration tank through Lifting

Sump. Then it is sent to Clarifier – II and then finally to DMF. Some part is sent for

non-process application and remaining to Lagoon for disposal.

The condensate water generated from Sugar – Co-gen unit is sent to Condensate

Polishing Unit (CPU) for treatment. The flow sheet is given below:

Fig. 5: Sugar CPU Flow Sheet

The major impurity contents of sugar factory condensate are trace organics and more particularly

the Ammonical Nitrogen which can prove detrimental for reuse applications. The treatment

scheme for condensate polishing unit involves the utilization of biological mode, specially

developed to treat not only trace organics, but basically the Ammonical nitrogen. The treatment

scheme therefore comprises of an Anaerobic – Aerobic approach. In this, rather than the

hardware provided in the form of civil structures and mechanical equipment, the software, i.e.

the process kinetics and reaction controls are important.

Although, the characteristics of condensate are fairly uniform with reference to period, it is

desirable to provide some cushion for minor variations in the form of equalization tank. This also

serves as a part of composite and complex biological system specially developed as the treatment

scheme. The condensate is subjected to anaerobic and aerobic biological modes selectively to

cater for and treat the two main impurities. Care is taken to optimize the treatment structures as

well as the energy inputs, thereby minimizing the capital as well as working expenditures.

b. For Distillery

Spent Wash Treatment

The condensate water generated from distillery unit is sent to Condensate Polishing Unit

(CPU) for treatment. The flow sheet is given below:

Fig. 6: Distillery CPU Flow Sheet

The working of Distillery CPU is similar to that of Sugar CPU. However two clarifiers and one

Aeration tank is added in the process in addition to the components present in Sugar CPU.

Total spent wash generation is 1280 KLD (8 KL/KL). After MEE, 20% Spent wash will be used

as compost (organic fertilizer) and remaining will be burnt together with coal in new

incineration boiler for distillery.
