Natural gas dehydration process: using separation technology to reduce the water dew point and hydrocarbon dew point of natural gas, and using fractionation technology to produce liquefied gas and stable light hydrocarbons.

1、 Dehydration: Gas enters from the booster station, first injected with hydrate inhibitor methanol, then enters the natural gas three-way heat exchanger for heat exchange and cooling with condensate and oil, and then enters the propane evaporator for heat exchange with liquid propane refrigerant, and then enters the clean oil absorption tower for separation. The separated natural gas is mainly divided into four types: natural gas, condensate, water, and oil. The separated natural gas enters the three-way heat exchanger and exchanges heat with the incoming natural gas to increase the temperature, and then goes to the compressor inlet of the booster station for pressurization. After separation, the natural gas condensate also enters the three-way heat exchanger to exchange heat with the natural gas and heat up, and then enters the condensate separator. The separated oil phase enters the fractionation unit for light hydrocarbon recovery, the water phase enters the wastewater storage tank, and the residual natural gas is pressurized by the tail gas compressor and returned to the inlet of the dehydration and dehydrogenation unit.

2、 Dehydration: The separated oil phase and condensate from the condensate separator enter the deethanizer tower. The non condensable gas at the top of the tower is pressurized by the compressor and returned to the feed gas inlet. The mixed hydrocarbons at the bottom of the tower enter the liquefied gas tower. The gas at the top of the liquefied gas tower is condensed by the air cooler and enters the liquefied gas spherical tank. The light hydrocarbons at the bottom of the tower exchange heat with the mixed hydrocarbons and condensate, and are then cooled by the product air cooler. Afterwards, some stable light hydrocarbons are used as absorption oil and pumped back to the light oil absorption tower by the lift pump, while the rest are sent as products into the stable light hydrocarbon spherical tank
