青海油田存在丰富的伴生气资源,为有效提高油田开发综合利用水平,努力提高伴生气轻烃收率以及产品质量具有十分重要的意义,也可创造客观的经济效益和社会效益。以采油一厂尕斯联合站为例,在伴生气稳定轻烃回收装置的原料气预处理、原料气增压、脱水、冷凝分离、制冷系统、精馏等单元在满足工艺设计要求的情况下,往往还会出现原料放空、产品质量不达标、产品收率低于设计数值等诸多问题,尽可能提高整个系统生产的连续性,是进一步提高收率的有效途径。
There are abundant associated gas resources in Qinghai Oilfield. In order to effectively improve the comprehensive utilization level of oilfield development, it is of great significance to improve the yield of gas and light hydrocarbons and the product quality, and also create objective economic and social benefits. Taking the gas station of Gas Production Plant No.1, for example, in the process of gas feed pretreatment, feed gas pressurization, dehydration, condensation separation, refrigeration system, rectification and other units meeting the process design requirements, , Often there will be many problems such as emptying of raw materials, non-compliance of product quality, product yield lower than design value and so on. It is an effective way to further improve the yield as much as possible to improve the continuity of the whole system.
