Abstract: An apparatus having various conduits moves liquid by passing gas up through it. A collector conduit transports the liquid to the bottom of the unit. A gas-lift conduit mixes the liquid and gas at the bottom and transports the mixture upwards, owing to the rising action of the bubbles and the resulting decreased density of the gas/liquid mixture. At the top of the gas-lift conduit, some of the gas may escape from the liquid and out of the apparatus. The lifted liquid may exit the apparatus at an elevation higher than the entry point of the liquid or may be directed down through a down and out conduit. A one way valve or equivalent configuration may be used to limit flow to one direction.
