    Abstract：The goal of Mahe oil and gas treatment facility is to control hydrocarbon dew point and water dew point of export gas. Condensate gas from Mahe Gas Flied is treated by adopting such technologies as MEG injection for antifreezing, J-T valve throttling for refrigeration and low temperature separation for dehydration and hydrocarbon dew point control, and condensate gas from the field is treated by adopting 2-stage depressurization flash + stripping process. Such problems exist in oil and gas treatment facility as unreasonable EMG regeneration system design, much MEG regeneration loss, unreasonable condensate oil residual heat utilization and hydrocarbon and water dew points of export dry gas affected by direct export of pressurized rich gas. After adopting some technical improvement measures, the oil and gas treatment facility can save fuel gas of 32.18 ×104 m3 MEG loss can be reduced by 15.55t and condensate oil output is increased by 231.0t annually. Therefore, technology improvement of Mahe Field oil and gas treatment facility is necessary.
