叙述了将 4L - 2 8/ 0 5 - 8型石油气压缩机改造为 4L - 2 0 / 0 5 - 1 6型石油气压缩机的技术方法、过程和经验。通过压缩机升压改造可改变轻烃工艺参数 ,提高收率 ,降低吨烃成本。从而对轻烃回收装置的技术改造提供了经济的方法。
The technical method, process and experience of converting 4L - 2 8/0 5 - 8 LPG compressors into 4L - 2 0/0 5 - 1 6 LPG compressors are described. Through the compressor boost transformation can change the light hydrocarbon process parameters, improve yield and reduce tons of hydrocarbon costs. This provides an economical way to retrofit light hydrocarbon recovery units.
