SYSTEM AND METHOD FOR CONCENTRATING GAS

摘要

Systems and methods for producing a product gas are provided. In one embodiment, a system includes at least one separation bed to separate adsorbable components from a gas source, a valving means to selectively direct gas from the gas source to the at least one separation bed, at least one sensing device associated with the at least one separation bed to sense the progress of an adsorption zone within the separation bed, and a controller. The controller includes logic to read the output of the at least one sensing device and control the gas separation process based on the progress of the adsorption zone.

1. A system for producing a product gas, comprising:
a product gas separator, comprising a first separation bed to separate absorbable components from a gas source; a product tank to store product gas; a pressure sensor associated with the product tank; at least one adsorption zone sensing device associated with the first separation bed to sense the progress of an adsorption zone within the first separation bed and provide an output; a controller, comprising logic to:
read the output of the pressure sensor;read the output of the at least one adsorption zone sensing device; andcontrol the separation of the adsorbable components from the gas source based on the pressure of the product gas and the progress of adsorption zone within the separation bed.
