The present invention relates to an apparatus and a method for efficiently and cost-effectively removing moisture from pressurized gas stream to any required low level. The invention adopts an irregular matrix of finned pipes to remove the moisture as liquid and solid deposits. Clogging is completely eliminated in the freezer and heat recuperator of this apparatus. The dew-point of the dried gas may be reduced to under -100 DEG F. The method and the apparatus provided by the present invention are universally applicable to the dehydration of all kind of gases, and, hence, can replace all the three major dehydration methods and dehydrators currently in the market, i.e., the solid desiccant absorption, the liquid desiccant absorption, and the refrigeration dehydration. No BTEX pollutant is emitted to the atmosphere when applied to natural gas dehydration. In particular, it provides environmentally benign, self-powered, compact, and low-cost natural gas dehydrators for remote sites where no outside power supply is available.
