Determination of hydrogen chloride in liquid phase EDC

The purpose of determining hydrogen chloride in liquid EDC (ethylene dichloride) is to protect EDC against corrosion by HCl during transport or storage.

For all other analytical solutions in the oxychlorination process, please browse the On-line Analyzers Suite under Products & Solutions.


All commercial available EDC must be free of hydrogen chloride (HCl) to prevent corrosion of the storage and handling equipment. For this reason it is advisable to monitor downstream the purification column the HCl concentration in  EDC by ionic detection using conductivity.

Product type: Process analyzers
