NATURAL GAS DEHYDRATION EQUIPMENT Russian patent published in 2009 - IPC F17C5/02 F25J3/08 

FIELD: oil-and-gas production.

SUBSTANCE: natural gas dehydration equipment with a double-stage cooling of incoming gas consists of gas preliminary stripping equipment and cooling unit with container for liquefied gas storage and mixer for cooling and liquefied gas. Cooling unit equipped with two sequentially located heat-mass transfer apparatus with fittings for gas supply and gas disposal which do not interact with water and insoluble cooling liquid, and mixer located on the gas line, which connects fitting for gas disposal of the first and fitting of gas supply of the second heat-mass transfer apparatus. Heat-mass transfer apparatus made as hollow packed columns or flooded bubble columns.

EFFECT: arrangement of easy and reliable natural gas dehydration during preparation of its liquation and compression, stabilising of gas content in terms steamed water content after natural gas dehydration procedure, design simplification and decrease dehydration equipment of metal content, design simplification of a automobile gas filling station or liquation stations, simplification of automation works of dehydration equipment installation and decrease of operational costs.
