• Currently, our factory is suffering from high desalter ph and high A-Tower ovhd ph. Therefore, bfw or demi water injection is being considered as desalter water. (Currently, striped water and ovhd water are being reused) I am concerned about the problem caused by amine and phosphate in bfw. Do you have any experience in using bfw or demi-water as desalter water?

    High pH in the overheads is usually caused either by excessive neutraliser / ammonia injection (simple enough to fix) or processing of crudes that have been dosed with H2S scavengers.

    Using demin or boiler feed water sounds like a very expensive way to solve the problem.  Instead, speak to your desalter chemical supplier about acidification of the desalter wash water.
