Abstract
Recovery of free emulsified oil from the wastewater is an important process of Waste Water Treatment Plant (WWTP) in a refinery. This is done in sub-unit called Dissolved Air Flotation tank (DAF). In this unit the sulfides, Phenols and Heavy metal ions are also removed by the addition of chemicals like H2O2 (Oxidation of Mercaptans), NaOH and H2SO4 (Adjustment pf pH) and Polyelectrolyte (De-emulsifier) etc. The optimal dosage of above chemicals for the performance of DAF of a refinery is studied with the variation of pH, concentration of H20 and Poly-electrolyte.
