Gerlach, C R; Heath, R T

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 are provided by a single stage double acting piston in a cylinder with fluid intake and exhaust valving and passages to alternately fill and exhaust the motor side of the cylinder while the opposite pump side of the cylinder is 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. Intake and exhaust of wet glycol to the motor side of the cylinder is controlled by gas applied to another spool type valve rod.
