AHDEB油田原油处理装置的原油稳定单元超负荷运行情况比较严重,气体处理装置的液化气回收单元投产后,产生的大量轻油回掺到原油处理系统,进一步加重了原油稳定单元负荷。现场运行及定量分析表明,轻油回掺后不会对外输原油产品蒸气压造成可观察到的明显影响,但对二级分离器和原稳塔气相负荷影响比较显著。建议在优化气体处理装置运行参数的基础上,直接将轻油掺入稳定原油。 The crude oil stabilization unit of the AHDEB crude oil processing unit is in overloaded operation. After the liquefied gas recovery unit of the gas processing unit is put into operation, a large amount of light oil is added back to the crude oil processing system, further aggravating the load of the crude oil stabilization unit. The field operation and quantitative analysis showed that the light oil can not significantly affect the vapor pressure of the crude oil output after the re-admixture, but has obvious influence on the gas phase load of the secondary separator and the original steady tower. It is recommended to optimize the gas processing plant operating parameters based on the light oil directly into the stable crude oil.
