Why CoC Deserves Continuous Control Cycles of concentration (CoC) is the single most influential control variable in a cooling tower loop, governing water consumption, scale risk, and chemical cost simultaneously. Conductivity is the field-proven proxy for CoC because it correlates tightly with total dissolved solids (TDS) and can be measured continuously without reagents. CoC quantifies…

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,…
Why Desalter pH Matters More Than Operators Sometimes Realize Crude desalting sits between the tank farm and the atmospheric column, and its job is deceptively simple: remove salts, sediment, and free water before crude enters the furnace. Yet the chemistry inside a desalter drum is a delicate balance. Chlorides in the incoming crude hydrolyze at…
Refinery effluent streams routinely expose sensors to free oil, aromatics, and H2S concentrations that degrade elastomers within 6–12 months if wetted parts are not upgraded. Wastewater treatment spending across the refining sector is rising as effluent limits tighten and produced-water reuse mandates spread—a direction confirmed by every major market study of the sector, even though…
