摘　　要：通过分析文23气田三甘醇脱水装置存在的问题,提出了设置闪蒸罐、甘醇贫富液换热采用高效板式换热器、将隔膜式甘醇循环计量泵换为能量转换泵、实现再生塔塔顶外循环量可调、优化工艺参数等改进技术与措施,增强了脱水装置的可调节性和可操作性,降低装置的操作费用和能耗,降低三甘醇损失。On the basis of an analysis on some problems existing in Wen23 TEG dehydration devices, some improving measures are put forward, such as: installing flash drum, adopting efficient plate heat exchanger of glycol rich and lean solution, replacing diaphragm glycol cyclic metering pump with energy conversion pump,adjustable outer circulation of regenerating column top, and optimizing technical parameters. Results show that these measures can enhance their adjustability and operability, and reduce the operating cost and energy consumption as well as TEG loss. Thus, they have popularization value for the design and technical innovation of dehydration devices.
