What Does Real-Time Conductivity Data Reveal About Crude Desalter Performance? Answers from Shanghai ChiMay Key Takeaways Conductivity is the most direct online proxy for chloride and salt content in desalter effluent water — often better than pH alone at diagnosing separation quality. A rising conductivity trend at stable pH indicates emulsion instability or surfactant contamination,…
The Science of pH Control During Crude Desalting Operations: A Shanghai ChiMay Technical Brief Key Takeaways Desalter emulsions break most efficiently at pH 5.5–7.0; drifting above pH 7.5 destabilizes water droplets and promotes chloride carry-over to downstream units. Wash-water pH is the single most controllable variable in a two-stage desalter, and continuous inline measurement —…
