摘要：采用Aspen Plus对某海上油田处理量为220×10~4m^3/d的天然气三甘醇脱水装置工艺流程进行模拟优化,对天然气脱水装置中主要操作单元吸收塔的工艺参数进行研究。结果表明:本文利用Aspen Plus建立的天然气TEG脱水系统计算模型可靠。随着TEG循环量上升天然气干气含水量下降明显;塔板数增加能有效的降低TEG循环使用量,塔板数和TEG循环使用量之间存在寻优关系。在本装置天然气脱水过程中塔板数为9的条件下最佳TEG循环量为1m^3/hr,天然气干气含水量从687.71mg/m^3降低到35.1mg/m^3。操作压力和原料气进料温度也对干气含水量有一定影响。
Abstract： The natural gas TEG dehydration system in an offshore oilfield of a 220×10^4 m^3/d dehydration plant was stimulated by Aspen Plus, The paper analyzed and optimized the technological parameters of the absorption tower. The results indicate that the calculation model of natural gas TEG dehydration system stimulated by Aspen Plus was reliable. With the increase of TEG circulation rate, the water content of net natural gas decreases significantly. With the increase of plate number could decrease TEG circulation rate effectively and there are researches on optimization between TEG circulation rate and plate number. In tins natural gas TEG dehydration plant, the best recycle flux is 1 m~/hr while the plate number is 9, and the water content of net natural gas decreases from 687.71 mg/m3 to 35. l mg/m^3. Operating pressure and the natural gas feed temperature also have influences on natural gas dehydration
