Abstract: A pump system for use in a gas dehydration system having an absorber/contactor and a reboiler is used to pump glycol or another fluid through a natural gas dehydration system. The pump system includes a gear pump connected to an electric motor for pumping glycol from the reboiler to the contactor/absorber. The motor may be powered by a thermoelectric generator that uses temperature differences in the gas dehydration system fluid to convert heat into electric energy. The pump system may also include additional pumps for moving fluid from the absorber to the reboiler, for moving a second fluid through a heat trace loop, and/or for driving peripheral components.

Abstract: Metals from sulfate leach solutions derived from sulfide ores are electrowon in a cell divided by a permionic membrane whereby metal pregnant solution is fed to the cathode compartment and sulfuric acid is generated in the anode compartment.
