- 摘要:
随着环保、节能要求的不断提高,油田伴生气回收利用逐步趋于完善。为提高伴生气回收装置的运行效率,提高C+3收率的同时降低设备能耗,采用HYSYS软件对直接换热(Direct Heat Exchange,DHX)工艺的运行参数与能耗和C+3收率的相关性进行模拟研究、分析规律,并通过现场实践验证模拟数据与现场运行数据的相关性。验证表明，压力与温度的变化均会对轻烃回收系统的能耗和收率有明显影响:当系统压力为1.8 MPa、低温分离器冷凝温度为-42 ℃、DHX塔回流温度为-58 ℃时,DHX工艺从设备能耗、C+3收率方面可达到最优效果,全年可实现轻烃增产233.6 t、节能降耗 7 008 kW·h。研究结果表明，软件模拟与现场验证相结合的试验方法可有效应用于轻烃回收过程中的参数优化、节能降耗、提质增效等方面研究,DHX工艺能耗分析及节能研究对轻烃生产具有一定指导意义。
With the continuous improvement of environmental protection and energy conservation requirements, the recovery and utilization of associated gas in oil fields has been further enhanced. In order to improve the operation efficiency of the associated gas recovery unit, increase the recovery rate of C+3 and reduce the production energy consumption, HYSYS software was used to simulate the correlation between the operating parameters of DHX process, energy consumption and C+3 recovery rate, analyze the performance pattern, and verify the correlation between the simulated data and the field operation data. Through data analysis and field tests, it is concluded that the change of pressure and temperature will have a significant impact on energy consumption and yield of light hydrocarbon recovery system. When the system pressure is 1.8 MPa, the condensing temperature of the low temperature separator is -42 ℃, and the reflux temperature of the reabsorption tower is -58 ℃, the DHX process can achieve the optimal effect in terms of equipment energy consumption and C+3 recovery rate, and can achieve a light hydrocarbon production increase of 233.6 t/a and energy consumption reduction of 7 008 kW·h/a. The research results show that the experiment method that combined software simulation with field test verification can be effectively applied to the research of parameter optimization, energy conservation and reduction in power consumption, quality improvement and efficiency enhancement in the light hydrocarbons recovery process. The energy consumption analysis and energy conservation research of DXH process have guiding significance for the production of light hydrocarbons.
