Abstract: This paper mainly introduces the operation status and problems of the tracing system in acrylic acid plant. It discusses and analyzes the feasibility of optimization revamp of low temperature heat utilization of the plant. Through optimization revamp of the on-site process flow of hot water system and condensate system, the problems of tracing fouling and blockage in the hot water system and water hammer in the condensate system of the device are solved. This can eliminate the on-site safety hazards and achieve energy conservation and emission reduction.

Key words: hot water system, condensate system, low temperature heat optimization revamp, energy conservation and emission reduction
