Condensing and absorbing gas compression unit and variants thereof

Abstract

A condensing and absorbing gas compression unit includes a cooler. A product outlet of the cooler is coupled to an inlet of a separator. A liquid outlet of the separator is coupled to an inlet of a pump. The pump outlet is coupled to a condensing unit, wherein the condensing unit comprises a condensing liquid-driven gas ejector A liquid-driven ejector product outlet is connected to an inlet of the cooler.

What is claimed is: 
     
         1 . A condensing and absorbing gas compression unit comprising:
 a cooler;   a separator, having a cooler product outlet connected to an inlet thereof;   a pump, wherein a separator liquid outlet is connected to an inlet thereof; and   a condensing unit wherein a pump outlet is connected to a condensing liquid-driven ejector liquid inlet, wherein a liquid-driven ejector product outlet is connected to an inlet of the cooler.   
     
     
         2 . The compression unit of  claim 1 , wherein the ejector operates at full condensation with liquid discharge at its outlet. 
     
     
         3 . The compression unit of  claim 1 , wherein an ejector motive fluid weight flow rate is from 3.3 to 500 times greater than weight flow rate of the compressed gas. 
     
     
         4 . The compression unit of  claims 1  wherein a gas product outlet of the separator is connected to a gas inlet of the ejector. 
     
     
         5 . The compression unit of  claim 1  wherein further comprising an ejector motive fluid recirculation loop having a liquid makeup. 
     
     
         6 . The compression unit of  claim 5  wherein the liquid makeup has a boiling range with an initial boiling point of at least an initial boiling point of light liquid in the separator. 
     
     
         7 . The compression unit of  claim 1 , wherein a motive liquid pressure at the ejector liquid inlet is at least 350 pounds per square inch gauge. 
     
     
         8 . The compression unit of  claim 1  wherein the liquid-driven gas ejector comprises liquid and gas inlet ports, a motive fluid nozzle, a feed chamber, and a throat, wherein a distance between a end of a tip of the ejector motive fluid nozzle and the an entrance to the ejector throat entrance is at least 0.12 inch and at most 5.0 inches.
