胜利油田河口压气站 7 5×1 0 4m3/d轻烃回收装置中 ,除干燥器设计压力为 1 0MPa外 ,其它工艺设备 (塔、分离器、换热器等 )的最低设计压力均高于 1 8MPa ,为升压改造提供了设备流程基础。将压缩机 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。经过升压改造、轻烃工艺参数和流程的改变 ,提高了收率、降低了吨烃成本。对轻烃回收装置的技术改造提供了较经济的方法。
In Shengli Oilfield Estuary Compressor Station, the minimum design pressure of other process equipment (tower, separator, heat exchanger, etc.) is higher than that of the light hydrocarbon recovery unit of 7 5 × 10 4m 3 / d except that the design pressure of the dryer is 10 MPa 1 8MPa, provided the basis for the equipment flow for the booster transformation. The compressor 4L-2 8/0 5-8 type of LPG compressor into a 4L-2 0/0 5- 1 6 type LPG compressor. After the boost transformation, light hydrocarbon process parameters and process changes, improve the yield and reduce the cost of tons of hydrocarbons. The light hydrocarbon recovery unit provides a more economical method of technological transformation.
