Dow and Veolia system wins ultrafiltration deal for new Total floating oil production unit

Dow Water and Process Solutions and Veolia Water Technologies are to provide ultrafiltration technology for Total’s new Moho Nord offshore floating deep water oil production unit off the Republic of the Congo coast.

An ultrafiltration (UF) system designed and supplied by Veolia Water Technologies using Dow IntegraFlo UF elements will produce high quality water for use in pressure maintenance in the subsea oil wells feeding the Moho Nord floating production unit.

Dow technology will be used in the removal of suspended solids and bacteria from 210,000 barrels of sea water a day in a pretreatment stage. Prior to injection into the oil reservoirs the pretreqted water will be fed into a sulphate removal unit equipped with Dow Filmtec SR90 elements.

Sulphate removal prevents reservoir scaling and souring of the oil.
