In the vinyl chloride synthesis plant, the main analysis tasks of the synthesis workshop are the analysis of the synthesis gas from the synthesis furnace, the analysis of the material composition entering the primary distillation tower, and the analysis of the exhaust gas after rectification.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. studied the content of trace water and low-boiling impurities in vinyl chloride monomer by chromatography, optimized the chromatographic column, discussed the separation effect and operating conditions, and verified the accuracy of the method. At the same time, the general measurement examples of trace water and low boilers in the raw gas, synthesis gas and tail gas of vinyl chloride system are listed, and the characteristics of chromatographic analysis of trace water are discussed.
