Abstracts: In chloralkali industry includes Soda Ash, Caustic Soda, sodium chlorides, etc. A soda ash is a material that use to make a washing soda. Here DCW company located in Dhrangadhra for manufacturing of soda ash from raw material limestone, salts, ammonia etc. In this mfg. process to get 98-99 % pure soda ash. This soda ash is send to detergent making company. During the lime extraction from lime link step from lime is recovered as some remains in the effluents. This effluent stream contains soluble lime due to presence of lime amount in effluent, which is losses, at present lime in effluent by vibroscreen to recovered efficient amount of lime. For this they give to us this opportunity to solve problem improvement of lime recovery from wastage stream removed from thickner. We accept this opportunity to solve this problem and we worked out modify of design of thickner. While modify this process we get 93% lime recovery from the thickner. In this designing process we are used for two thickner. Soda Ash is used in washing soda, in glass industry use act as silica and Sodium carbonate is also used as a descaling agent in boilers.
