Abstract: Triethylene glycol dehydration method is currently the most effective method of natural gas dehydration,its dehydration effect is remarkable,and its operation and maintenance are convenient. However,triethylene glycol has problems such as deterioration and incomplete regeneration during the regeneration process,affecting the dehydration effect. Taking the triethylene glycol dehydration device of an oilfield in Bohai as an example,the process flow,operational problems and optimization measures are explored. Effective measures are formulated and adopted to improve the dehydration effect of the device,which provides guarantee for the safe and stable operation of gas transmission pipelines.

Key words: natural gas dehydration, triethylene glycol, study of measures, dew point
