Abstract
A liquid pump 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 first manual control valve normally regulates the stroking rate of the glycol driven pump motor. The pump is also automatically regulated by a control system sensitive to temperature changes in the circulating glycol in order to lower the circulation rate of glycol under certain operating conditions to prevent overheating of the glycol circulation system.
