气相法聚乙烯装置循环气压缩机的扩能改造

CAPACITY-EXPANSION REFORM OF CYCLE GAS COMPRESSOR IN GAS-PHASE POLYETHYLENE PLANT

气相法聚乙烯装置在扩容改造后,循环气压缩机运行工况有了较大的变化。通过对压缩机改造后的气动性能核算,并对传动部件强度进行校核,根据计算结果,确定了最经济的改造方案。改造实施后压缩机运行平稳,各项性能指标正常,取得了良好的效果,对同类装置的扩容改造提供了参考。

After the capacity-expansion reform of the gas phase polyethylene plant,the operating conditions of the cycle gas compressor have changed greatly.Through aerodynamic performance calculation of the reformed compressor and check on the strength of the transmission parts,the most economic reform plan is determined according to the calculation.After the implementation of the reform,the gas compressor runs smoothly;the performance indicators are normal and good results are received.This provides reference for the capacity expansion reform of similar plants.
