The low-temperature dehydration skid is mainly composed of low-temperature separator, coalescer, coiled heat exchanger, atomizer, drain valve and its pipeline, valve, pressure gauge, etc. The low-temperature dehydration unit is based on low-temperature methanol as absorption solvent. Methanol not only acts as natural gas hydrate inhibitor and antifreeze, but also can be used as acid gas removal solvent, so as to dehydrate natural gas, recover natural gas Acid gas removal is closely integrated into a whole, simplifying the process flow.
