Fluid-flow system, device and method

Abstract

Methods, devices, and systems are disclosed for combining fluids of different pressures and flow rates in, for example, gas gathering systems, gas wells, and other areas in which independently powered compressors or pumps are not desired.

1 - 20 . (canceled) 
   
   
       21 . A gas gathering system comprising:
 a first input of gas at a first pressure;   a second input of gas at a second pressure, the first pressure being higher than the second pressure;   a means for combining the first and the second inputs of gas;   wherein the means for combining uses pressure differences between the first input of gas and the second input of gas to power the means for combining.   
   
   
       22 . A gas gathering system as in  claim 21  further comprising a gas/fluid separator receiving gas and fluids from a well;
 wherein the first input of gas comprises gas from the separator, and a liquids tank, receiving liquids from the separator, wherein the second input of gas comprises vapor from the tank.   
   
   
       23 . A gas gathering system comprising:
 a first well;   a first flow line of gas from the first well;   a first separator connected to the first flow line;   a first separated gas flow line connected to a first input of a means for combining at least two gas flows having different pressures;   a second well;   a second flow line of gas from the second well;   a second separation connected to the second flow line;   a second separated gas flow line connected to a second input of the means for combining;   wherein the means for combining comprises a first input volume and a second input volume; and   a pressure differential between the first input volume and the second input volume causes a portion of the first input volume to be combined with a portion of the second input volume at an output volume.
