Abstract:
A method of drying gas used in a pneumatically driven pressure intensifier, the pressure intensifier having pistons and used in a pressure swing adsorption system, the pressure swing adsorption system, including a pair of molecular sieve beds each connected to a first and a second valve, respectively, the first and the second valves each connected to a source of pressurized gas, the method comprising flowing pressurized gas to opposite sides of the pressure intensifier to position the pressure intensifier pistons;flowing pressurized gas through a first activated bed to dry the gas and to pressurize one side of the pressure intensifier to shift the pressure intensifier to a first position and venting gas from the other side of the pressure intensifier through a second activated bed; venting gas from the one side of the pressurized bed pressure intensifier through the first activated bed and flowing pressurized gas through the second activated bed to dry the gas and to pressurize the other side of the pressure intensifier to shift the pressure intensifier to a second position.
