Abstract

The invention relates to a natural gas heating and regeneration integrated dehydration device and method, the device comprises an inlet filter (1), a first dehydration tower (2), a second dehydration tower (6), an outlet filter (3), a circulating compressor (4), a gas-liquid separator (5) and a cooler (7), and the first dehydration tower (2) and the second dehydration tower (6) are switched for adsorption and regeneration. According to the device disclosed by the invention, the heater and the drying tower are designed in a built-in manner, the inlet and the outlet of the tower adopt a filter element form and can be randomly disassembled, assembled and replaced, the structure meets a larger flow area, the device does not need an additional instrument air compression system, air filtered at the inlet can meet instrument air source conditions, energy consumption is avoided, and the gas quality is clean.

Description

technical field [0001] The invention provides a natural gas heating and regeneration integrated dehydration device and method. The built-in design of the heater and the drying tower reduces the loss of pipeline valves and heat, and is applied to the dehydration of natural gas. Background technique [0002] According to when the water content of the natural gas entering the gas storage device exceeds the provisions of GB18074-2000 "Compressed Natural Gas for Vehicles", the station should be equipped with a natural gas dehydration device. The dehydration process should adopt the solid adsorption method. Two sets of dehydration equipment should be used in parallel, one of which The system is running, and another system is regenerating, and the alternate operation period should be 6-8h. [0003] Traditional dehydration devices are usually composed of front and rear filters, adsorption towers, regeneration towers, circulation compressors, electric heaters, and gas-liquid separato...
