Switzerland: Oil Separation Sulzer Acquires License for Total’s Wash Tank Technology for Oil Processing
Sulzer’s Chemtech division has been granted a license covering the Total-patented Wash Tank Technology for Oil Processing.
Winterthur/Switzerland — 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 significant simplification of the topsides crude oil process.
The company will commercialize the licensed technology along with its static mixing technology as well as patented oil/water emulsion distributors which evenly distribute the feed across the full cross section of the hull tank and generate a constant droplet size (for a given flow) to maximize the system performance. The company announced that its testing capabilities and CFD services form an integral part of a properly designed solution for each specific facility.
This technology has been in operation for several years on the Usan, Pazflor and Clov FPSO’s, as well as on the recently started Moho Nord / Likouf FPU. Martin Linge FSO and the Egina FPSO are also equipped with this technology and will start up in the near future. All of these assets are operated by Total.
