Abstract

Hydrocarbon for dewatering are injected via a turbulence chamber into a sleeve of moulded cellulose acetate set coaxially within a cylindrical sepg. vessel. The pH of the sleeve material is adjusted to be slightly acidic so that water in the form H-OH becomes polarised in the micropores of the sleeve wall to the molecular form. The water is exuded via the pores inot the sepg. vessel where it settles to the bottom while hydrocarbons with water content 0.005% be drawn off at the top.
