Transformation of hydrogen chloride synthesis system
Technical improvement measures were proposed to address the issues related to DCS interlocking logic during the shutdown of hydrogen chloride synthesis furnaces,and the automation level and intrinsic safety of the device were improved.From the perspectives of safety,environmental protection,and economy,modifications were made to the venting system of the hydrochloric acid tank and the hydrogen chloride sampling pipeline.The on-site environment was improved to a certain extent,and cost reduction and efficiency increase were achieved.Other urgent issues that need to be addressed in the hydrogen chloride synthesis unit were proposed.
