【正文】 ved temperament piped natural gas requirements. In the high carbon removal ratio can choose H 2S, recycling a small amount of low operating costs, loss, very wide application. Main methods for dehydration of natural gas lowtemperature dehydration, dehydration solvent absorption, solid adsorption and chemical reaction of dehydration dehydration. Dehydration solvent absorption method at present is the most beneficial, is the most widely used.
