Ramification of Mechanical Equipments in Abatement of Pollution – A Case Study in a Petrochemical Industry

Abstract:

Industrial or Trade effluent defines, in legal term, any liquid, gaseous or solid substance discharged from industry premises. The discharge of untreated effluents is injurious to public health besides to the life and health of animals or plants or of aquatic organisms. Effluent treatment involves mechanical, physical, chemical and biological processes; in majority of non-natural processes, mechanical equipment is used to breakdown the wastes into environmentally stable components, and their suitability depends on the type of the generated waste, process, efficiency of equipment used, etc. A few of these include – diffusers, fixed and floating aerators for injecting compressed air, Bio-discs which rotate on shafts for biological treatment, incinerators for burning solid wastes, cyclones and wet/dry Scrubbers for air treatment, Filter press, Centrifuge to remove water/moisture. Petrochemical product manufacturing activity is a highly polluting industry. The effect of mechanical equipments in such a petrochemical unit, manufacturing Phthalic Anhydride, Maleic Anhydride, Fumaric Acid and Maleic Acid, at Tamil Nadu has been studied and the performance of the equipment in the aeration components of the ETP system evaluated; the study concludes with suggestions for supplementary improvement.
