In order to develop and utilize natural gas effectively, reduce the production cost, it is necessary to study natural gas dehydration technology, guiding program of natural gas purification process. The paper reviewed 5 kinds of conventional dehydration techniques of natural gas used in domestic and oversea oil and gas fields, including low temperature separation method, solvent absorption method, solid adsorption, membrane separation and supersonic separation. The principle, development status and problems of every dehydration technique were summarized. In comparison with the conventional dehydration technique, the paper focused on the recent new membrane separation dehydration technology and supersonic dehydration technology. At last, the development direction China's natural gas dehydration technology and the key technology were prospected.
