Sulzer’s Chemtech division has been granted a license covering the Total-patented Wash Tank Technology for Oil Processing. The main purpose of this technology is to enhance the removal of water, salt and contaminants from oil and emulsions, by a controlled distribution of the feed into the bottom of a hull tank of an FPSO/FSO/FPU which transforms the water-in-oil dispersion into an oil-in-water one where high efficiency phase separation takes place more easily. The technology also involves a simplification of the topsides crude oil process.
