CHAPTER 1 INTRODUCTION

1.1 BACKGROUND

India is the largest producer of sugarcane and sugar. However the Sugar Factories cannot survive in healthy condition on a single product i.e. sugar. Hence it is necessary to develop sugar factory into affiliated chemical complex and use the valuable by-products more profitably. Molasses is a very important by-product of the sugar industry. The profit earned by conversion of molasses to alcohol shall be much higher than the value released by sale of molasses. There is a good demand for alcohol in the country as production and consumption of alcohol in India is quite balanced. The target of alcohol demand as projected in the perspective plan for chemical industry, prepared by government of India, Ministry of Industry, Department of chemical and petrochemicals is 2400 millions litres per annum by year 2000. In addition, now a days, there is a good potential to export alcohol out of country. Alcohol has assumed a very important place in the economy of the country. The importance and utility of alcohol is well known as an industrial raw material for manufacture of a variety of organic chemicals including pharmaceuticals, cosmetics, potable alcohol etc. This is partly due to high costs of products produced through petroleum route, consequent to the phenomenal increase in petroleum price. Further, it is a potential fuel in the form of power alcohol when blended with petrol. Alcohol is a substitute to the imported petroleum. Being produced from renewable source it is an environmental friendly product. Large demand is also anticipated for its use as fuel. Use of alcohol as an ingredient in beverages is well known. It is a major source of revenue by way of excise duty for the State Governments. The location of distillery site is shown in the District map of Maharashtra. (Figure: 1.1)

1.5 PURPOSE OF EIA & EMP Industrial activities such as distilleries invariably involve utilization of natural resources and generation of waste substances and they may have adverse consequence to the environment. However, mankind as it is developed today can not live without taking up these activities for his food, security or other needs. Hence, there is a need to harmonies developmental activities with the environmental concern. Consequently, there is a need to harmonious developmental activities with the environmental concern. EIA is one of the tools available with the planners to achieve the above goal. It is desirable to ensure that the project activity is sustainable. Hence, the environmental consequence must be characterized early in the project cycle and accounted for in the project design. The objective of EIA is to fore see the potential environmental problems that would arise out of the proposed development and address them in the project planning and design stage. The present EIA report incorporates the environmental consequence of the proposed distillery project along with the measures adopted in the distillery for control of pollution and enhancement of environmental quality. Alcohol is produced in the distilleries by fermentation and distillation processes. Molasses, a waste/byproduct of sugar industry is used as raw material by most of the distilleries. Spent wash produced as an effluent is the major pollutant from the distilleries. It is highly contaminated with inorganic and organic matter. Proper handling and disposal of spent wash is necessary to prevent its adverse effects on the environment. State and Central pollution control authorities have issued guidelines to the distilleries for treatment and safe disposal of spent wash. Accordingly, the distillery spent wash will be treated and disposed through bio-methanation, compost, evaporation and incineration. The salient feature of the proposed expansion is zero discharge of spent wash to environment. The proposed distillery project is listed under EIA Notification dated 14-09-2006 of Ministry of Environment and Forests (MoEF), Government of India. Further, It is categorized under Category -A of Schedule 5 (g) of this notification. As per the above notification, prior clearance from MoEF is mandatory before establishment of this industry. Under Environmental Protection Act (EPA) 1986, before establishment of any project it is also mandatory for the project proponents to obtain consent on environmental angle from State pollution control board. EIA studies have to be conducted and its report is to be prepared for submission to the authorities along with the prescribed application forms to secure their clearance for the proposed project. Hence, the present report is prepared for submission to MoEF New Delhi.



1.6 SCOPE OF THE STUDY MITCON Consultancy & Engineering Services Ltd., Pune has been entrusted the task of carrying out EIA/EMP studies in order to obtain regulatory clearances from the the Expert Appraisal Committee (EAC) , Industry – II of MoEF for the proposed project of 45 KLPD Distillery. The EIA studies were carried out for various environmental components so as to assess the anticipated adverse impacts due to the proposed facilities and to suggest suitable mitigation measures. Expert Appraisal Committee (EAC) for the Environmental Appraisal has issued TOR for the preparation of the EIA report vide F.No. J-11011/118/2014-IA II (I)dated 24th July 2014, based on the documents submitted and presentation made by the project proponent. Copy of ToR along with compliance report is attached Annexure-1.

Note: A growth of 3% in potable use and a 3.5% in chemical and other use has been assumed. (Source: Report of the Committee on Development of Biofuels published by planning commission April 16, 2003.)

The Table 2.2 reflects that the estimated ethanol consumption / utilization by chemical industry (which is growing at 3.5% p.a.) rose from 527 Th KL in 2001-02 to 2054 Th KL in 2011-12. which reflects increase in the demand of ethanol by industry. Also the demand for potable alcohol (which is growing at 3% p.a.) is projected to increase from 648 Th. KL in the year 2001-02 to 1028 Th. KL in the year 2016-17. The Tables 2.1 and 2.2 reflect the ever growing demand and supply gap in the ethanol production. Against this background ISML plans to propose molasses based distillery of 45 KLPD to meet the ever growing demand of RS/ENA for potable purposes and chemical industry. 2.3 PROPOSED DISTILLERY 2.3.1 Location The proposed distillery is located at factory premises at Bhagwantnagar, Upalai (T),

2.3.6 Steam Balance Proposed Distillery Unit The distillery employs multi pressure system for achieving steam economy. The working steam pressure is 3.5 kg/cm2g. The steam from back pressure turbine will be supplied to fuel ethanol plant using 23.5 TPH boiler. The total steam requirement for the proposed fuel ethanol plant will be as under Steam Quantity:

-aerator, 1.00 TPH Steam will be generated through slop/ effluent fired boiler. 2.3.7 Raw material requirement Proposed Distillery Unit

As the sugar plant will crush about 5.00 lakh MT of sugarcane at the rate of 3200 MT/Day, molasses of around 24560 MT will be produced and will be utilized by the distillery unit, leaving 29619 MT outside molasses (from sister concern) as the total molasses requirement is 54179 MT for optimum level of operation.

Hence the ISML can easily generate the required quantity of molasses and procured molasses from nearby sugar mills to operate plant for 330 days. Molasses storage tanks – 2Nos.X9000MT Molasses Balance: Molasses require for 45 KLPD Distillery for 1 day- 164 MT 330 days- 54179MT Own Molasses- 24560MT Procured Molasses (sister concern)- 29619MT 2.3.8 Manpower requirement The total manpower requirement is 75 nos. out of which 63 will be workers and 12 will be staff members.



2.3.9 Manufacturing Details 1. Fermentation

Molasses, diluted with water to the desired concentration is metered continuously into a single tank fermenter. Additives like 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 35deg.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 hydrocyclones (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 hydrocyclone 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 hydrocyclone and the wash tank protect the separator from erosion damage by removing grit and similar hard particles.

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 ethanol production, ensuring high process efficiency.

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 vapours from the rectifying column to preheat wash. Further heating is done in an exchange of heat with 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 analyser. 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 vaporizes and is carried, along with water vapour, to the top of the wash column from where it goes to the rectification column. As wash travels down the analyser, 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.

Propagation: The propagation section is a feeder unit to the fermenter. Yeast, either Saccharomyees cereviseae or Schizosaccharomyees pombe (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. Conversion of sugar to ethanol 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.

2. 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 ethanol 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 by-products 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 reboiler 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 fuel ethanol 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 feed (Rectified Spirit) ,pumped from the storage tanks, Is heated through the heat exchanger by the dehydrated alcohol ,then heated Rs of 93% to 96% is fed to the top of the distillation column. The liquid passes through the distillation column where ethanol is stripped of. The alcohol free liquid called spent lees is separated and discharged from the bottom of the distillation column and the ethanol stream, with strength of about 96% by volume, is removed as vapor, at the top section of the distillation column and feed to the molecular sieve unit after a super heating about 115oC by steam in the heat exchanger. Fusel oils are removed from an intermediate point of the column in order to avoid any risk of flooding of the column and feed to the static settling device where are separated from the weak water which are recycled to the column. The distillation column has an operating pressure of about 160 kPa(A) and is heated with low pressure steam by means of reboiler. This solution shows following advantages:

Total recovery of steam condensate which is recycled to the steam boiler at high temperature with consequent increasing of the efficiency of the reboiler (higher production of steam per unit of fuel)

Lower cost for softening of demineralization of raw water to be fed to the boiler as steam condensate does not need any treatment

Lower quantity of stillage, potential source of pollution The super-heated ethanol stream removed at the top of the distillation column feeds one of the two sieve beds is now in regeneration mode.



The second sieve bed when in regeneration mode (under vacuum) and receives a small amount of vapour from bed working in over pressure. As soon as regeneration is finished (a regeneration cycle lasts about 5 minutes), an automatic control system changes the operating conditions of the two sieve beds in order to have the first sieve bed in regeneration and the second one in dehydration mode. The dehydration process releases a vapour ethanol stream with a very small amount of water (500 ppm or less), which is condensed in the condensor cooled in the heat exchangers and sent to the storage as dehydrated alcohol. The regeneration process releases a certain amount of absorbed water and ethanol, which are condensed in the condenser and recycled to the column. Cooling media of the first cooling step of the dehydrated alcohol (condenser) is the regeneration stream recycled to the distillation column and cooling media of the second cooling step of the dehydrated alcohol (condenser) is the fed stock coming from the storage tanks, which is preheated as herein above described. Remaining vapors and liquid are condensed and cooled by cooling water in S &T or P&F heat exchangers. The unit operation is fully automatic and all operations are governed by logics executed by a PLC Control system. The process flow diagram is given in Annexure 2.

2.3.10 Pollution control measures Spent wash treatment and disposal options 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. Considering this aspect, following treatment system / Options may have to be considered by the Distilleries.

Primary treatment Secondary treatment Disposal

Concentration (Reboiler)

Composting On land

Concentration (60-65 Brix)

Incineration of Concentrated Spentwash

As Auxiliary fuel for boiler

Technology Alternatives 1. Anaerobic digestion process: Anaerobic digestion is the biological decomposition of organic matter in absence of oxygen. In the recent years, the escalation of energy costs and environmental concerns have increased the interest in direct anaerobic treatment of distillery spentwash. Anaerobic digestion consists of the two distinct stages, which occurs simultaneously. The first stage is known as Acid Fermentation consist of hydrolysis and liquefaction of high molecular weight organic acid-by-acid forming bacteria. Acetic acid and butyric acid is the most common product in the first stage. The second stage is known as Methane Fermentation or Methanogenesis. It is the conversion of organic acid into methane and carbon dioxide by acid splitting methane-forming bacteria. The major benefits and limitations are as follows. Limitations: 1. Relatively long periods of time are required to start up the process. 2. It is a Primary treatment method. The treated effluent BOD will be in the range of

5000-8000 mg/L and hence an adequate post-treatment (BoD



The mixing of spent wash and press-mud (50-70% moisture) is being carried out (3.5:1 proportion) in trenches with the help of excavator- cum –loader for mixing, turning, loading and unloading of compost material. Addition of cow dung will provide bacterial culture required for composting. It is observed that in the first five days, fungal activity is predominant and in subsequent days bacterial activity continues until stabilization of organic matter into humus is accomplished. Limitations:

1. Area requirement for Bio-composting process is very high. 2. Press mud requirement is high. 3. Total time required for completion of one composting operation cycle is very

high. 4. It is not possible to continue composting process during rainy season as a result

of that it is essential to stop distillery operation if bio-composting is a method of effluents treatment.

5. Spent storage tank of huge capacity is required. 6. The distillery operation is permitted for not more than 270 days per Annum

3. Spent wash Incineration Technology:

The spent wash of a distillery process is a serious problem by way of threat to the environment. Its volume from continuous fermentation plant is as large as 480 KL/day for a distillery of 60 KL/day capacity if Mojj distillation technology of multi pressure distillation with integrated evaporator system has been used and it may vary as per different technologies of Praj as well as Biostil of Alfa- Laval 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. The concentrated spent wash generated after entire process of evaporation is then sprayed in a furnace with auxiliary fuel such as bagasse and is then burnt in a boiler.

Choice of Spent wash Treatment System In order to fulfill the Pollution Norms and to achieve zero Discharge and at the same time to operate distillery for the period more than 300 days per annum, Factory proposes to go for spent wash Concentration and Incineration Technology simultaneously generating Steam and Power for the process and Distillery. With effective utilization of such a technology big hurdle of spent wash disposal will be solved and distilleries will become zero effluent discharging units to be called as “Evergreen BIO- FUEL Refineries”.
