HIGH-PRESSURE NATURAL GAS DRYING UNIT Russian patent published in 2013 - IPC F04B39/16 B01D53/53 B01D53/04 

FIELD: machine building.

SUBSTANCE: high-pressure natural gas drying unit includes a pressure line, and a regeneration line with shutoff valves and control valves each. In the regeneration line there installed in series is an oil separator and heater and two absorbers connected in parallel through check valves. Each absorber is provided with a pressure sensor and a thermal converter. In addition, in the regeneration line there installed is a buffer capacity with a pressure sensor and a thermal converter and a circulating compressor with a pressure sensor, and in the pressure line there additionally installed is a dew point sensor connected to outputs of absorbers.

EFFECT: improving operating efficiency of automobile gas filling compressor stations owing to repeatability of regeneration process; reducing power consumption and improving the process automation.
