Abstract
The present invention provides for a method utilizing horizontal and vertical Adsorber bed(s) with multiple different reversible blower(s) and inputs operating in a vacuum pressure swing adsorption separation process to separate gases. The process is designed to provide a safer and more cost-effective adsorption system on a larger scale that captures and utilizes energy typically wasted during equipment transitions thereby achieving overall higher power efficiency.
Claims5
An apparatus for producing oxygen comprising:
- two adsorber beds each connected to two or more flow balanced reversible blowers through isolation valves, an equalization line with an adsorptive buffer vessel, and two product valves;
- and wherein a control method actuates rotating of said blowers sequentially in clockwise and anticlockwise directions to supply air to the inlet of one bed while regenerating the other bed by removing adsorbed nitrogen using a vacuum.
