Treatment of wastewater and Physicochemical characterization of Sludge collected from Petroleum refinery

Abstract

newline Waste generated in a huge amount during the processing of crude oil into useful products newlinesuch as petrol, diesel, liquefied petroleum gas (LPG), etc. in petroleum refineries has raised a newlineconcern worldwide. The direct discharge of waste in water bodies and land can cause harm to newlinehuman beings, other living beings and environment. The waste generated is highly toxic and newlinehazardous in nature. Therefore, the treatment of waste generated is necessary before the newlinedisposal/reuse. Mainly the two types of waste generated in petroleum refineries namely newlinepetroleum refinery effluent and the oily petroleum sludge has been discussed in this thesis. newlineMultiple type of treatment methods are reported in the previous literature studied. The literature newlinemainly reports the use of single type of metal salt for the treatment of effluent. I decided my newlineresearch objective as the treatment of wastewater collected from the effluent treatment plant by newlineusing catalytic thermolysis and coagulation and flocculation process using the CuSO4, FeSO4, newlineFeCl3, and 1:1 ratio (V: V) mixture of CuSO4 and FeCl3 as a catalyst and investigation of newlinephysicochemical characteristics of petroleum sludge for better remediation and reuse.
