Our desalter is facing a rag layer issue when we process cabinda crude. The brine turns black. It seems like our current emulsion breaker can not solve this problem. Is there any ideas or recommendations?

The brine quality is poor likely due to some oil carry-under, either caused by poor interface control or lack of separation due to a number of factors. The Tracerco Profiler can help operators monitor all process interfaces within the vessel and optimise their emulsion breakers when processing different crudes by measuring their effectiveness over time. The instrument can also detect asphaltenes and stabilised emulsions, monitor the interface height of fluids and solids in real time, help control wash water quality by increasing contact time and improving separation efficiency. Please get in touch if you would like to discuss further.
