华北油田永清站生产液化气的原料来自两个方面,一是本站对天然气经过浅冷、深冷分离后得到的天然气重组分;二是利用其他天然气处理站分离出的天然气重组分。两部分原料一同进入液化气生产装置进行深加工,将混合轻烃中的液化气和轻质油分离。根据不同阶段液化气中烃类组分的差异,永清站液化气生产过程中使用的机泵有多级离心泵(如滑片泵)、低温泵、小排量高速泵等。在实际的生产过程中,滑片泵频繁发生故障,影响
The raw materials for liquefied gas produced by Yongqing Station in Huabei Oilfield come from two aspects. One is natural gas heavy components obtained after light and cryogenic separation of natural gas, and the other is natural gas heavy components separated by other natural gas processing stations. Two parts of the raw materials into the liquefied gas production unit for further processing, the mixed light hydrocarbon liquefied gas and light oil separation. According to the difference of hydrocarbon components in liquefied gas at different stages, multistage centrifugal pumps (such as vane pumps), cryogenic pumps and small displacement high-speed pumps are used in the liquefied gas production process of Yongqing Station. In the actual production process, frequent vane pump failure, the impact
