| 摘 要： | 聚乙烯装置中流化气压缩机 1/2C40 0是核心设备。它是否正常运转将直接影响到装置的开停工。压缩机的密封气采用的是乙烯气 ,为保证压缩机长周期运行 ,又不影响流化气的组分 ,乙烯气是由一端打入压缩机 ,另一端排放至火炬 ,浪费很大。现介绍了在密封乙烯气出压缩机后的管路上连接一路至乙烯储罐 ,增加开关阀和压力表 ,并利用TDC 30 0 0的逻辑控制功能 ,实现密封乙烯气的回收控制 ,既节约了生产原料 ,又增加了密封的可靠性

| Abstract: | The fluid gas compressor 1/2C400 is the key equipment of the polyethylene plant.The seal gas of the compressor is ethylene gas.In order to ensure the compressor can run for a long period and not effect the composing of the fluid gas,the ethylene gas is input from one aspect of the compressor and output to the torch from the other aspect.The ethylene is wasted.Recently we connected the output pipeline of the seal gas to ethylene tank,added the on off valve and pressure transmitter,used the logical function of TDC 3000 to realize the recovery of the seal ethylene for saving the source and reducing the cost. |
