ABSTRACT:
A liquid motor is driven by pressurized wet glycol, received from an absorber of a natural gas dehydrating system, and utilizes the energy of the pressurized wet glycol to provide the primary source of energy for operating a pump for pumping of dry glycol from a reboiler to the absorber. A gas driven motor regulates the stroking rate of the glycol driven motor. The liquid motor and pump each have a two stage double acting piston in cylinders with fluid intake and exhaust valving and passages to alternately fill and exhaust the motor cylinders while the opposing pump cylinders are simultaneously alternately filled and exhausted. A spool type valve rod, associated with the glycol driven motor, is operated by the gas driven motor to regulate the rate of reciprocation of the glycol driven motor and to provide a secondary source of energy therefor.
