Isi artikel

Cleaner production is proposed to develop cleaner technology in vinyl sulphone industry by adopting better technologies, better plants, better processing, better recoveries and better pollution control measures which is more convenient and viable for industry to increase their economical benefit in short time of pay back period and also to satisfy Gujarat Pollution Control Board rules. Scope of this project is that it helps us to increase maximum recovery of byproducts , to decrease loss in storage of raw material and also to decrease excess amount of raw material usage by proposed alternative technology of vinyl sulphone to satisfy Gujarat Pollution Control Board rules, to improve process and economics. In proposed process, it is possible by modifying hydrochloric acid absorption system or using falling film absorber decreases hydrochloric acid emissions from vent of caustic scrubber and also increase concentration of hydrochloric acid than conventional process, modifying storage system by using condensor to recover ethylene oxide vapor and providing new process technology decrease usage of excess raw materials, effluent etc.
