Abstract:
Disclosed are a compact natural gas pretreatment purification method and device suitable for an offshore platform, wherein the method and the device are suitable for pretreatment purification of natural gas mined on the offshore platform to remove heavy hydrocarbons, soluble salt ions, and most of the moisture from the natural gas. The mined natural gas is introduced from a gas phase inlet, sequentially passes through a spray washing unit, a gas-liquid distribution unit, a natural gas and washing water mixing and mass transfer unit, a spin generating unit, and a natural gas and washing water separation unit, and then flows out of a gas phase outlet. The removed liquid enters a liquid storage unit. Fresh water passes through the liquid storage unit, is injected into the spray washing unit by means of a pipeline circulation pump, and is then sprayed out. By treating the natural gas using this method, the soluble salt ions and most of the moisture are removed from the raw wet natural gas. The compact pretreatment method has the function of on-line treatment of natural gas and rapid removal of impurities and liquid on the offshore platform with a limited space.
