159 55. Caustic and Chlorine Plant Process Description: The process is based on Membrane Cell technology. The main steps in the process to manufacture caustic soda are Purification of brine. Electrolysis. Concentration and flaking of caustic soda solution. Brine Purification Brine for ion exchange membrane Chlor-Alkali process is prepared by dissolving salt in the return brine from the electrolysis plant, and purified in two stages. Primary purification removes impurities like calcium, magnesium, sulphate, iron, silica etc. Secondary purification is required to make brine suitable for the ion exchange membrane Primary Brine Purification: Primary Brine Purification section consists of Salt Handling system, Brine Saturator, Reactor Clarifier, Clarified Brine Tank and associated facilities. This process includes Brine saturation, chemicals dosage, reaction and sedimentation. The purpose of this process is to re-saturate the return brine with raw salt and to remove impurities from the saturated raw brine. The return brine is fed from the top of the Brine Saturator and saturated with salt. The salt is continuously supplied to the top of the saturator by a Belt Conveyor System. Suspended solids in the brine are removed by settling in the Clarifier provided with water seal & insulated from the sides. The brine, thus clarified, flows into clarified Brine tank over the weir of Clarifier & is pumped out and recirculated to the brine system before reactor for better clarification. Slurry is periodically measured for better control. A part of slurry is sent to Sludge Filter System. The clarified brine is sent to Secondary Brine purification section by clarified brine pump. Secondary Brine Purification: Secondary Brine Purification Section consists of Brine Filter and Ion Exchange Resin Column. This specially developed Ion exchange resin can remove multivalent cations harmful to the Ion exchange membrane. The brine thus purified is fed to Electrolyser and electrolysis is conducted. 159

160 Electrolysis Electrolyser Electrolyser consists of the metal anode and the activated cathode, the Ion exchange membrane, press unit for mounting cell frames, Cell frames holding the Ion Exchange membrane in between are fixed by the oil cylinder installed at the end of the press unit. This structure ensures no leakage of electrolytes because uniform pressure can be applied to gasket surface and cell frame of metal structure ensures no electrolyte leakage caused by deformation even after a long period of operation. Anolyte Circulation Anolyte circulation system is composed of Anolyte Circulation Tank and anolyte circulation pump. Anolyte is fed into each of anode compartment of cell frames through sub headers and hoses, and recirculated to Anolyte circulation Tank. Purified brine is fed to maintain anolyte concentration within a designed level. A part of the anolyte, is taken out from Anolyte Circulation Tank to Depleted Brine Tank by overflow. Anolyte Circulation system is designed to ensure steady and uniform distribution of anolyte to each cell and to cope-up with any change in electrolysis conditions such as ion rate change. The diluted brine collected in Depleted Brine Tank is sent to De-chlorination Tower for removal of Chlorine gas. Chlorine gas generated in electrolyser is separated in Anolyte Circulation Tank and sent to Chlorine gas cooling, drying and compression section. Catholyte Circulation Catholyte Circulation System is composed of Catholyte Circulation Tank, Catholyte Circulation Pump and Catholyte Cooler. Catholyte is circulated through cathode compartment of cell frames to Catholyte Circulation Tank by Catholyte Circulation Pump, and a part of it is taken out from Catholyte Circulation Tank to Caustic Soda Tank and sent out to caustic evaporation section. To keep the concentration of caustic soda at designed level, demineralised water is fed to catholyte inlet sub-header. Hydrogen gas generated in Electrolyser is separated from the catholyte in catholyte Circulation Tank and sent to Hydrogen Gas Cooling and Compression Section. Heat generated in electrolyser is removed by cooling water in Catholyte Cooler. De Chlorination of Return Brine De-chlorination section is composed of De-Chlorination Tower, De-Chlorination Tower Cooler, Ejector, Ejector Cooler and associated facilities. Return brine, (depleted brine) from Electrolysis Section is saturated with chlorine. In the tower, chlorine is stripped together with water vapor, and passed through De-chlorination Tower cooler. The vapour is condensed there and the chlorine gas is sucked by the steam ejector to Ejector Cooler. Steam is condensed there and the chlorine gas is then introduced to chlorine gas main line. The depleted brine dechlorinated through De-chlorination tower, still contains small amount of free chlorine which can cause damage to the filter elements in Brine Filters and damage ion exchange resin in Ion Exchange Resin Columns. Sodium sulphite is added to kill free chlorine. Return brine is then fed to Return Brine Tank & pumped to salt saturator. Caustic Concentration The caustic soda concentration system consists of triple effect falling film evaporators operating on backward feed flow scheme. 30% caustic solution 80 0C is fed to third effect evaporator. Vapours are separated from solution and concentrated solution of third effect evaporator is pumped to second effect evaporator after passing through two heat exchangers in series. In the second effect evaporator, flash 160

161 evaporation of liquor takes place and liquor is further heated by steam and vapors are separated in second effect evaporator to concentrate liquor. The concentrate from the second effect evaporator is pumped through first effect evaporator after passing through two heat exchangers in series. Steam at 11 Kg/cm2a pressure is used to attain required concentration of caustic. Chlorine Liquefaction & Bottling Chlorine Gas Washing and Cooling Chlorine Gas coming out of Anolyte circulation tank contains water vapour saturated at about 900 C and has little amount of Sodium Chloride as entrainment. Gas is first washed by process water in a direct contact scrubbing packed tower. Condensate is sent to dechlorination tower. The process water is in turn cooled by cooling tower. Cooled gas is then passed through a packed tower having chilled process water circulation at 160 C so as to cool the gas to reduce water vapors load. Chlorine gas temperature is generally around deg C as cooling below C will result into formation of Chlorine hydrate. Cooled gas is then dried with direct spray of sulfuric acid in packed towers. Chlorine Gas Drying The cooled chlorine gas is led to chlorine Gas Drying Tower. The moisture of chlorine gas is absorbed into sulfuric Acid of 98% concentration fed into the two stage chlorine gas drying tower, and gets diluted to 70% by absorption of moisture from chlorine gas. Chlorine Gas Drying Tower has a cooler to cool circulating sulfuric Acid. The Dry Chlorine gas is sent for compression. Chlorine Gas Compression Dry chlorine gas from chlorine Gas Drying Section is compressed to 4 MT/cm2 by using Acid Ring type Compressor. Chlorine Gas Liquefaction and Filling Chlorine gas from compressor is sent to chlorine Gas Liquefaction Unit to be condensed by the Freon 22 refrigerant. The unliquefied gases along with inert gas from Liquefier are sent to HCI Synthesis unit for burning with Hydrogen to produce HCl. Liquefied chlorine enters Chlorine Storage Tank from where it is transferred by means of compressed dry air to chlorine bottling section. Part of liquid Chlorine is vaporised and sent to nearby customers through pipeline. Waste Chlorine Neutralization / Sodium Hypochlorite Section Waste chlorine gas, only in case of plant emergency is led to the Sodium Hypochlorite Unit. Chlorine Gas during start up and plant tripping is fed to the absorption tower. This unit consists of packed tower in which caustic solution is circulated to absorb waste chlorine. Temperature of the liquid is controlled by heat transfer through plate type heat exchanger with chilled water. After a desired strength of sodium hypochlorite is reached, the solution is sent to a Hypo Reactor. Here it is reacted with fresh chlorine to produce marketable quality Sodium Hypochlorite. HCL Synthesis The HCI Synthesis unit consists of combustion furnace fitted with absorbers. The chlorine gas reacts with Hydrogen to form HCI gas which is cooled and absorbed in DM water. The flow rate of DM water is adjusted to obtain 30-33% HCI Solution. The flow rates of Chlorine and Hydrogen are controlled by flow 161

162 controllers. Safety Interlocking provisions are made which get actuated by flame protection device. The Hydrochloric Acid Solution is collected in a tank from where is pumped to HCI Storage Tanks. Hydrogen Bottling and Storage Hydrogen gas is compressed and filled in hydrogen cylinders banks of the customers and also stored in cylinder banks. Caustic Soda and Flaking Plant Flaker plant is a double effect evaporator. 32% Caustic is feed to produce 98% Caustic Flakes. Salt mixture (KNO3, NaNO2 & NaNO3) which is heated by burning Hydrogen is a heating media to increase Caustic lye temperature in final concentrator. 98 % Caustic flakes is then cooled and packed using a polythene liner to avoid moisture pick-up as it is a hygroscopic. Solid Waste Generation The membrane cells require brine of extremely good quality for electrolysis. Presence of even traces of Ca, Mg etc. are harmful to the membranes. Hence extensive treatment is required. This is done in two stages viz. primary treatment and secondary treatment. In the primary stage Ca, Mg impurities are chemically precipitated out of brine while sulphate impurities are removed by using latest nano-filtration sulphate removal system to minimize the solid waste generation. The solid waste will be sent to secured landfill site. After settling and filtration, brine is further treated in ion exchange columns, called as secondary treatment to remove traces of Ca, Mg to yield pure brine of quality suitable for membrane cells. The precipitated impurities containing Ca, Mg along with insoluble etc. are settled in a clarifier and are drawn out as thick sludge (4-10% w/w). This sludge is pumped to sludge filtration unit by clarifier sludge pump to minimize the quantity for disposal as well as to recover brine. The cake from the decanter is disposed to secured land fill site and clear filtrate brine is recycling back to clarifier. Chemical Reaction: 2 NaCl + 2H2O Cl2 + H2 + 2NaOH

172 59. Butane (R600a) Process Description: Propane &butane can be separated from LPG as a raw material sourced from refineries. Due to the presence of ethane and n-butane along with the desired s, they should either be removed or converted to useful s. Ethane being the most volatile of all, removed in the first column, working at a pressure of approximately 26 MT/cm2G, as off gas. Alternatively, in case ethane is not present in the sourced LPG this column is not required. Now Propane (R290) is removed in the second column, working at a pressure of around 15 MT/cm2G and sent to storage, leaving primarily n-butane &butane in the remaining gas mixture. Since our of prime focus is butane (R600a), a conversion (isomerization) of n-butane to butane is required. "Hydrogen Once through Butamer Process" technology provided by UOP (Honeywell) is one of the processes which take care of the conversion from n-butane to butane. This conversion reactor containing high activity chloride-alumina catalyst works integrated with a stabilizer column which purge out the remaining gases to scrubber or used as fuel. This technology requires Hydrogen make-up for isomerization reaction. Therefore after recovery of butane in the third column working at a pressure of around 6 MT/cm2G the n-butane gas is sent to the isomerization unit and converted into butane. Alternatively potential market for n-butane can be explored in order to avoid the isomerization process. Also an additional flare system to be considered for hydrocarbon venting in case of plant trip, start-upshutdown etc. Storage vessels for propane, butane and n-butane will be Spherical type high pressure storage vessels (Kindly refer the vapour pressure of the components.

182 ANNEXURE: 4 ETP DETAILS Existing & Proposed effluent treatment plant scheme The existing& proposed domestic and industrial effluent treatment plant shall be treated with four different streams as following: 1. Low TDS with Low Organic effluent stream 2. High TDS with High Organic effluent stream 3. Utility Effluent stream generated by cooling tower and boiler blow down 4. Domestic effluent stream Detailed explanation, including technical details of each wastewater stream to be treated in Effluent Treatment Plant has been explained in further sections of this chapter. 1. Treatment Scheme for Low TDS with Low Organic effluent stream : Stage wise effluent characteristics details Parameter Unit Inlet effluent quality Physiochemical Treatment Secondary treated quality followed by Bio Tower Secondary treated quality followed by Activated Sludge Process Tertiary treated quality Final treated quality Flow (Existing) Cu.

183 Low TDS with low organic effluent treatment plant shall be establish for treatment of COD less than 5000 mg/l, TDS less than 3000 mg/l, Fluoride < 50 mg/l and also for heavy metals like antimony, zinc, nickel, copper, barium, lead and iron with combine physio-chemical, anaerobic and aerobic biological process and tertiary treatment system. The collected influent is equalized in collection by continuous air diffusion system. Equalization Influent coming from different plant pits is collected in equalization tank. Through equalization ph is stabilized and chemical requirements are minimized for neutralization. Physio-chemical treatment Hydroxide and sulphide treatment shall be provided for removal of heavy metals and fluoride. For this process hydrated lime and ferrous sulphate dosed for removal of suspended solid, fluoride and heavy metals. In this system calcium shall react with fluorides, hydroxide (OH - ) &sulphate shall react with heavy metals. Flash Mixer The colloidal particles present in effluent require coagulation for flocs to agglomerate. In flash mixer, the coagulants viz., non-ferric alum or PAC, shall be added under rapid mixing. Flocculator The coagulated effluent shall be then fed to Flocculator where polyelectrolyte shall be added under slow mixing for formation of flocs readily settleable. Sedimentation Process In Tube Settler; suspended solids, calcium fluoride (CaF) and heavy metals are removal by sedimentation through Primary Tube Settler. Settled solid (Suspended Solid, Calcium Fluoride and metal hydroxide or sulphide) shall be sent to Filter Press for dewatering. The SS free supernatant shall be collected and sent to the equalization tank. 183

184 Bio Tower A bio tower operates by having the wastewater fall through a packed bed tower filled with permeable packing. The packing has both aerobic and anaerobic microorganisms growing on it. The bio tower shall be operated with recycling. Bio towers use stationary filter media for the treatment of wastewater. The following are several steps that are often considered to improve nitrification: The fixed film reactor and activated sludge process shall be run in series. This will allow most of the BOD removal to occur in the first stage and improved nitrification to occur in the second stage. The amount of ventilation and hydraulic recirculation is increased and shall be operated by 10 times recycling of feed rate. This will allow nitrifying bacteria to operate at increased growth rates. Hydraulic dosing shall be increased by high recirculation rates. Shearing off of excessive bio-growth shall allow enhanced ventilation and promote new growth for added nutrient removal. Activated Sludge Process In activated sludge process wastewater containing organic matter is aerated in an aeration basin in which micro-organisms metabolize the suspended and soluble organic matter. Part of organic matter is synthesized into new cells and part is oxidized to CO2 and water to derive energy. In activated sludge systems the new cells formed in the reaction are removed from the liquid stream in the form of a flocculent sludge in secondary settling tanks. A part of this settled biomass, described as activated sludge is returned to the aeration tank and the remaining forms waste or excess sludge. Physio-chemical treatment The supernatant from ASP shall be then fed to Flocculator where PAC / sodium hypochlorite shall be added under slow mixing for formation of flocs and destruction of micro-organisms. Sedimentation The treated effluent shall be then fed to tube settler for tertiary SS removal. Sludge Decanting and Dewatering The primary sludge from primary tube settler and biological sludge from Activated Sludge Process shall be collected in the sludge holding tank, and then fed in to the Filter Press or decanter for dewatering. Leachate 184

185 shall be transferred to the equalization tank and the dewatered sludge shall be stored in impervious designated area. The dewatered calcium fluoride and metal content sludge shall be sent to secured landfill site or shall be sold to actual users by confirming of the heavy metal content.

Equalization Utility waste water, DM plant waste water and blow downs from boiler and cooling tower shall be collected in collection tank. Physio-chemical treatment Acid, Alkali & coagulant pump shall be provided to pump Acid, Alkali & coagulant dosing in ph control tank. ph tank stirrer shall be provided to mix effluent & chemicals in the tank. ph indicator shall be provided in tube stirrer ph shall be interlocked with Acid & Alkali dosing pumps. Sedimentation Mix effluent from ph control tank shall overflow in tube settler. We are providing tube settler with cool deck media for better setting of suspended solids in tube settler. Settler sludge at bottom of tube settler shall be pumped in filter press feed sump. Filter Feed Sump: Tube settler shall over flow to filter feed sump collected effluent shall be pumped to dual media filter. For removing of suspended solids, turbidity & smell. We are providing dual media filter with one working & one 194

195 stand by condition. This dual media is periodically required to be cleared of accumulated solids by back washing the filter using fresh water in reverse flow sequence. Ultrafiltration System: Ultrafiltration (UF) is a form of filtration that uses a membrane to separate different fluids or ions. Ultrafiltration is not as fine a filtration process as Nano filtration, but it also does not require the same energy to perform the separation. Ultrafiltration also uses a membrane that is partially permeable to perform the separation, but the membrane's pores are typically much larger than the membranes pores that are used in Nano filtration. Ultrafiltration is most commonly used to separate a solution that has a mixture of some desirable components and some that are not desirable. One of the uses that demonstrate the usefulness of Ultrafiltration is separation of oil in an emulsion from water. In this case, oil emulsions, for example, machining coolant emulsions can have the oil separated and concentrated, with the water phase being discharged to sanitary sewer, and the concentrated oil phase being disposed of at a lower cost. Ultrafiltration is capable of concentrating bacteria, some proteins, some dyes, oils and colloidal or emulsified components. Ultrafiltration is only somewhat dependent upon the charge of the particle and is much more concerned with the size of the particle. Ultrafiltration is typically not effective at separating dissolved organic streams. Reverse Osmosis System: Reverse osmosis is a membrane separation process for removing solvent from a solution. When a semi permeable membrane separates a dilute solution from a concentrated solution, solvent crosses from the dilute to the concentrated side of the membrane in an attempt to equalize concentrations. The flow of solvent can be prevented by applying an opposing hydrostatic pressure to the concentrated solution. The magnitude of the pressure required to completely impede the flow of solvent is defined as the "osmotic pressure". If the applied hydrostatic pressure exceeds the osmotic pressure (see figure below), flow of solvent will be reversed, that is, solvent will flow from the concentrated to the dilute solution. This phenomenon is referred to as Reverse Osmosis. The figure illustrates the concepts of osmosis, osmotic pressure and reverse osmosis schematically. 195

The sewage with the help of cutter pump (1 Working + 1 Stand by) transfer to bar Screen chamber Bar Screen: Raw sewage from the source is usually received into the bar screen chamber by gravity. Screen provided will remove all floating and big size matter such as plastic bottles, polythene bags, glasses, stones, etc., which may otherwise choke the pipeline and pumps. Oil & Grease Trap: If the sewage generated includes maximum quantity from kitchen and canteen, there is a possibility of higher concentrations of oil and grease in the raw sewage. It needs to be removed before biological treatment as it otherwise may cause problems for biological treatment. A small tank with a baffle wall is need for oil & grease trap. Equalization: Sewage with having BOD between mg/l and TSS between mg/l is collected in equalization tank. Through equalization ph is stabilized and chemical requirements are minimized for neutralization. 198

199 Fluidized Membrane Bio Reactor (FMBR): In this system raw sewage enters at the top of the tank. Air is introduced at the bottom of the tank through floating type diffused aeration system. Media will be in suspension because of the turbulence created by the air. The bacteria required for the oxidation of the organic matter is attached to the media and some part is suspended in the tank. After oxidation, the bacteria grow in number and need to be separated from the aeration tank liquor. The lamella section inside the biological reactor helps in clarification and separation of the bacteria (sludge) and clear overflow flows into chlorine contact tank. Lamella plates helps in increasing the settling area and removing the particles effectively in a smaller plan area. Alum dosing of around 5-6ppm in the clarifier for improving the settling of suspended solids. In chlorine contact tank, Sodium hypo Chlorite (NaOCl) is added for disinfecting the clarified sewage. 10% concentration of NaOCl with 10-15ppm dosage is in Chlorine Contact tank. Tertiary Treatment: Multi Grade Sand Filter Function: Filtration of suspended particle. Water with the help of filter feed pump is transferred to MGF. Activated Carbon Filter Function: Deodorization, Decolourization & Dechlorination After ACF, the water pass through UF, this acts as filter assisting in further reduction of BOD, COD, & TSS. Treated Water Collection Tank: The treated sewage water shall be collected in treated water collection tank for reuse in Gardening or in monsoon season it shall be treated with Utility effluent stream for further reuse. Sludge Decanting and Dewatering: The sludge from the Clarifier to be removed from the bottom of the Clarifier and transferred to sludge drying bed. Sludge fed in to the centrifuge for drying of the sludge & the dried sludge may be used as manure for development of greenbelt & the substrate may be recycled back to the equalization tank. 199

202 Online flow meter Online flow meter has been provided at final outlet of ETP. Rainwater Harvesting Rainwater harvesting is a mechanism involved in collecting, storing and using rainwater when it is most needed. A rainwater harvesting system comprises of various stages transporting rainwater through pipes or drains, filtration, and storage in tanks for reuse. It is proposed to have Roof-top rain water harvesting at site. We have considered only the Roof tops of the clean terraces for rain water harvesting considering the chemical industry. The roof-top rain water will transfer through a network of pipes linked through storm water drain. The storm water connected to storm water collection sump. Rain water will be transferred from collection tank to Utility collection tank for reuse. We collect the first rain water in collection tank through storm water drain and reuse it after appropriate treatment. 202
