By supplying liquid selectively only when liquid is required for the condensation of the vapor, water is saved. | 12-17-2015 |
20150369229 | Downhole Chemical Injection Method and System for Use in ESP Applications - Provided is a chemical injection pump that is installed below an electric submersible pump. In general, the chemical injection pump is either driven by an electric motor that draws power from the electric submersible pump motor or from energized fluid leaving the electric submersible pump output port. The electric submersible pump provides electric or hydraulic power to run the chemical injection pump. Therefore, no surface chemical injection pump is required and hence less space is needed. | 12-24-2015 |

20160102673 | Method and System of Compressing Gas With Flow Restrictions - The gas compression method/system restricts flow of emulsified liquid-gas mixture through many substantially radial capillary tube-passages in a rotating disk by either one-way valves, narrowing the passages, hydraulic impedance and/or reinforcement of coriolis forces in terminal end tail segments of the capillary passages. Compressed gas is released from peripherally collected compressed gas-liquid emulsion (beyond the terminal ends of the tubes) in a arcuate peripheral disc space when the compressed gas bubbles emerge from the peripherally collected emulsion. A compressed gas drain draws off gas from the peripheral space. Liquid drain draws off liquid from the space. In different embodiments, radial outboard flow through the capillaries is effected by various one-way valves which may be a single valve in the passage or multiple valves. Coriolis force in tail segments is enhanced by angular displacement in the direction of rotation. Valves may be used in combination with such tail-end segments. | 04-14-2016 |
20160138615 | ASPIRATOR PUMP WITH DUAL HIGH PRESSURE STREAMS - A three stream aspirator includes an upstream passage for receiving and discharging a motivator stream, a low pressure passage for receiving and discharging a low pressure stream, and a Venturi for receiving and discharging the motivator stream and for drawing the low pressure stream through the low pressure passage.
