摘要
三甘醇脱水工艺因其投资低压降小等优势而广泛应用于各油田,而三甘醇脱水效果的好坏直接影响着天然气外输及销售,因此,基于HYSYS软件,对三甘醇脱水工艺进行模拟,并对比分析了诸如原料气进塔温度、TEG贫液浓度及温度、吸收塔操作压力及吸收塔塔板数等因素对于三甘醇脱水效果的影响程度,并合理优选以上参数,以达到最好的脱水状态。以上研究对于油田提高天然气脱水效率,降低投资成本具有一定的理论根据和指导。
Because of its advantages of small investment and low pressure drop, TEG dehydration process is widely used in various fields, however, effect of TEG dehydration directly affects the transmission and distribution of natural gas.In this paper, based on HYSYS software, the TEG dehydration process was simulated, the influence of feed temperature, TEG lean solution concentration and temperature, absorber operating pressure and plate number of absorption tower on TEG dehydration degree was analyzed, and then reasonably optimized parameters were determined in order to achieve the best state of dehydration. The research can provide a certain theoretical basis and guidance for increasing gas dehydration efficiency and reducing the cost of investment.
