炼厂吸收稳定新工艺探讨

Discussion on a novel process for absorption stabilization unit in refinery

针对吸收稳定系统"干气不干"、液化气收率低的问题,通过分析现有工艺存在的问题,提出了解吸塔再平衡工艺技术,并进行了模拟计算和水力学分析,验证了工艺技术的可行性。研究表明,新工艺技术可降低干气中C+3组分体积分数,提高液化气收率,经济效益显著。

There are problems of " dry gas containing wet " and low yield of liquefied gas in the absorption stabilization system.Through analyzing the existing problems in the existing technology,a rebalancing technology for the desorbing tower is proposed,and concerning simulation calculation and hydraulic analysis are performed in order to verify the feasibility of the technology.The research shows this new technology can reduce the content of C3+components in dry gas and increase the yield of liquefied petroleum gas,showing a remarkable economic benefit.
