离心压缩机缸体堵塞原因及在线清洗技术的运用

摘要

扬子石油化工公司物流部火炬气回收装置离心压缩机在运行过程中，由于火炬气组分较杂，机组在运行过程中，火炬气易聚合并堵塞压缩机缸体流道，使得压缩机运行周期短，检修费用高，火炬气回收装置不能高负荷稳定运行，后来通过与南京工业大学合作攻关，对火炬气和堵塞物的全组分进行分析，进行调温聚合实验，决定增加脱盐水在线清洗设施，降低缸体流道中火炬气温度，及时冲洗堵塞物，从根本上确保了离心压缩机的长周期高负荷稳定运行。

Summary

The gas of flare easier block the cylinder of compressor when the mixed components of gases transfer in the flare gases recycle system of YPC Logistic Department, and the result caused that the system can not be run smoothly with higher capacity and the running period shorten, and also higher maintenance cost needed, so after researching and investigation together with Nanjing Industry University, we determined add a device that online cleaning the system with the water of missing salt after did an experiment by adjusting the temperature of polymerization after sampled and analyzed the components of the gases and the blocked substance, and reduce the temperature of flare cylinder pipe, and flush the blocked materials in the compressor to ensure the machine running smoothly with a longer periods and higher charges ultimately.
