摘　　要：针对常规伴生气脱硫脱碳处理系统溶液循环量大、能耗高等问题,从有效能分析的角度出发,对重点耗能单元进行了有效能损失和有效能效率计算,通过关键参数调节实现了能耗和产品质量的双优化,确定了系统持续优化的发展方向。结果表明:吸收单元和再生单元的有效能损失占比分别为35.7%、64.3%,且吸收塔、再生塔、塔底再沸器、塔顶冷凝器和冷却器的有效能损失较大,说明重点耗能单元为再生单元;通过再生塔塔顶酸气热量回收、节流阀压力能回收和半贫液工艺改造回收等手段,部分设备的有效能损失大幅降低,有效能损失从14.430×10^(6)kJ/h降至11.114×10^(6)kJ/h,节能降耗效果明显。In view of the problems of large circulation of solution and high energy consumption in conventional associated gas desulfurization and decarbonization treatment system,the effective energy loss and effective energy efficiency are calculated for key energy consuming units and equipment from the perspective of effective energy analysis.The double optimization of energy consumption and product quality is realized by adjusting key parameters,and the development direction of continuous optimization of system is determined.The results show that the ratio of effective energy loss of absorption unit and regeneration unit is 35.7%and 64.3%respectively,and the effective energy loss of absorption tower,regeneration tower,bottom reboiler,top condenser and cooler is larger,indicating that the key energy dissipation unit is regeneration unit.Through the recycling tower top acid gas heat recovery,throttle valve pressure energy recovery and semi-lean liquid process transformation recovery and other means,the loss of effective energy is reduced from 14.430×10^(6) kJ/h to 11.114×10^(6) kJ/h,which is obvious on the energy conservation and consumption reduction effect.
