Experimental study of supersonic dehydration for natural gas

The velocity of natural gas can be increased to supersonic speed with natural gas supersonic dehydration unit due to the application of vortex tube.Liquid water would be separated in cooling process,and removed with cyclone unit.Gas and liquid are separated in a separation unit.The system is composed of pressure stabilization vessel,vortex tube,secondary separator,etc.After lab test and field test of natural gas supersonic dehydration,dew point of inlet gas and dry gas is measured in test: dew point of dry gas was-16.6℃ with a pressure loss percentage of 40% in the lab test,while that of dry gas was-9℃ with a pressure loss percentage of 70% in field test.It is showed by test result that a high removal efficiency of water is achieved with the supersonic method.
