裂解气压缩机聚合结垢问题是影响其性能和长周期稳定运行的瓶颈,压缩机的聚合结垢会导致压缩机振动升高,甚至停车。分析了裂解气压缩机结垢引起中压缸振动波动问题的原因,提出了添加分散型阻聚剂在线处理压缩机结垢问题的措施,达到抑制结垢、消除振动波动的目的。 Cracking gas compressor polymerization and scaling problems affect its performance and long-term stable operation of the bottleneck, the compressor polymerization scaling will cause the compressor vibration increased, or even stop. The reason of the vibration fluctuation of medium pressure cylinder caused by the fouling of cracked gas compressor was analyzed. The measures to deal with the scale fouling problem of the compressor by adding dispersant polymerization inhibitor were put forward to achieve the purpose of inhibiting fouling and eliminating the vibration fluctuation.
