SRP systems from Veolia Water Solutions & Technologies today account for approximately 40 percent of the world's seawater sulfate removal capacity.
MODEC Offshore Production Systems has awarded a contract to Veolia Water Solutions & Technologies for their PSVM FPSO project for the BP Angola PSVM (Plutão, Saturno, Vênus and Marte) field development in Block 31 Angola. The award is for the supply of a seawater treatment system comprised of pretreatment, vacuum deaeration and sulphate removal package (SRP) systems with a capacity of 31,800 m3/day (200,000 BWPD). Also included within the scope is an integrated seawater reverse osmosis (SWRO) system for process washwater sized at 20,000 BWPD.
The SRP is designed to remove sulphates and other divalent ions from injection water to enhance oil recovery using Dow/Filmtec SR90 membranes. The removal of these ions reduces the tendency of barium sulphates and strontium sulphate scale to form in the reservoir. The wash water is used in the crude oil desalting process.
“"This is the first SRP project to be awarded to VWS by MODEC, and can be attributed, in some manner, to the success of our previous SRP for BP, the FPSO Greater Plutonio, also located in Angola (Block 18), completed in 2005," says Brian Baillie, Sales Manager for Veolia Water Solutions & Technologies. "That installation remains the world's largest capacity SRP." ”

Providing A Complete Barrier
The sulphate removal process removes sulphates and other divalent ions from the injection seawater to enhance oil recovery.
The sulphate removal process uses a membrane-based system that removes sulphates and other divalent ions from the injection seawater to prevent the formation of barium sulphate and strontium sulphate scale in the subsea injection piping system and in the reservoir itself.
