A Clean Technology to Treat Wastewaters Produced in the Oil Industry: Operation with Static Mixer
Year: 2008
Type: article
Abstract: This work presents a new device conceived on a laboratory scale, for treating wastewater in the petroleum industry. Up-stream water must be treated according to the specifications of the environmental legislation in force, which, in Brazil, establishes maximum total oil and grease (TOG) of 20 mg/L. The functioning principle of the equipment is based on the combination of liquid-liquid extraction and the innovative phase inversion method®. The paper presents a comparison between the utilisation of mechanical agitation and static mixer to improve the mass transfer of oil from aqueous to solvent phase. Two kinds of elements are used into the static mixer in view of evaluating the performance of them on the global separation efficiency. Results show the “honeycomb ” static element is advantageous when compared with the plate one and mechanical agitation. By keeping all operational variables constants an increase of 30 per cent on efficiency of extraction was obtained by using the “honeycomb ” element instead of the plate one. 1.
