Principle analysis and treatment technology of tail gas polymerization in MMA unit
In view of a series of bottleneck problems such as material polymerization blockage in the tail gas pipelines of methyl methacrylate(MMA)plant and unstable operation of the tail gas recovery system,it found out the causes of material polymerization by analyzing each component of the material in the tail gas system.Based on the design concept of plant,the technology of the tail gas recovery system of the plant was upgraded,and the easy polymerization components in the tail gas were removed by means of absorption and cooling,so as to reduce the polymerization of materials in the pipeline and improve the stable operation of the tail gas recovery system of the plant.The results showed that the stability of the tail gas recovery system was improved obviously after the technology upgrade.
