Abstract
A method for concentrating a single gas component from a gas mixture is disclosed. The method utilizes concentration units and recovery units to concentrate the single gas component which is often at very low concentrations in the gas mixture. This method allows for the recovery of a valuable gas depending upon application such as oxygen and Ar-40.
Claims43
A method for recovering in higher concentrations and higher yield a gas component from a gas mixture wherein said gas component is present in said gas mixture in low concentrations comprising recovering a waste stream from a concentration unit and feeding said waste stream to a recovery unit and feeding a product gas stream from said recovery unit and a feed stream of said gas mixture to said concentration unit.
A method for recovering a gas component in high concentrations and high yield from a gas mixture wherein said gas component is present in said gas mixture in low concentrations comprising feeding a combination of said gas mixture and a product gas stream from a recovery unit to a concentration unit and feeding the waste stream from said concentration unit to said recovery unit.
A method for recovering a gas component from a gas mixture wherein said gas component is present in said gas mixture in low concentrations comprising the steps:
- Feeding a waste stream from a concentration unit to a recovery unit;
- b) Combining a feed of said gas mixture and a product gas stream from said recovery unit;
- c) Feeding the combination of step (b) to said concentration unit;
- and
- d) Recovering said gas component from said concentration unit.
