Technical exchange on major overhauls of York propane compressors! To commemorate posting my first message on HaiChuan, I’m giving away a copy of the basic guide to propane compressors* as a gift, in the hope of building friendships with everyone! {:1_90:} The York propane compressor is used in the natural gas liquefaction stage of the natural gas dehydrogenation and dehydration process! Natural gas dehydrogenation and dehydration process: This process uses separation techniques to lower the water dew point and hydrocarbon dew point of natural gas, and employs distillation to produce liquefied gas and stable light hydrocarbons. I. Dehydration: The gas enters from the pressurization station; first, methanol, which is a hydrate inhibitor, is injected into it. Then it passes through a three-stream heat exchanger where it exchanges heat with condensate and oil to cool down. Subsequently, it enters a propane evaporator to exchange heat with liquid propane refrigerant, and finally it goes into an oil purification absorption tower for separation. The separated natural gas is mainly divided into four components: natural gas, condensate, water, and oil. The separated natural gas enters a three-stream heat exchanger where it exchanges heat with the natural gas entering the plant to be heated, and then proceeds to the compressor inlet at the pressure boosting station for pressurization. After separation, the natural gas condensate also enters a three-stream heat exchanger to exchange heat with natural gas and be heated, before entering the condensate separator. The separated oil phase enters a fractionation unit for the recovery of light hydrocarbons, while the water phase goes into a wastewater storage tank. The remaining natural gas is pressurized by an exhaust compressor and then sent back to the inlet of the dehydration and dehydrocarbonization unit. II. Dehydrogenation: The oil phase and condensate separated by the condensate separator enter the deethanizer; the non-condensable gases at the top of the tower are pressurized by a compressor and sent back to the raw gas inlet, while the mixed hydrocarbons at the bottom of the tower go into the liquefied gas tower. The gas at the top of the liquefied gas tower is condensed in an air cooler before entering the liquefied gas sphere tank. The light hydrocarbons at the bottom of the tower first exchange heat with the mixed hydrocarbons and condensate, and then are cooled by a product air cooler. Subsequently, some of these stabilized light hydrocarbons are sent back to the light oil absorption tower as absorption oil via a lift pump, while the remaining portion enters the stabilized light hydrocarbon sphere tank as a product.
