Adsorptech specializes in the design and supply of Oxygen VPSA systems. We also provide process consulting, research, and refurbishment services on existing Oxygen VPSA and PSA systems. There are many different names associated with the adsorption method of producing industrial gases - PSA, VSA, VPSA and Oxygen Concentration Generators. In many cases, the names are used interchangeably. The Adsorptech oxygen system has both a vacuum and positive pressure step in our proprietary process and therefore prefers the term VPSA.
Adsorptech has the engineering, fabrication, product management, operations skills and proprietary know-how to provide world-class lowest-life-cycle cost VPSA, and PSA systems. Adsorptech relationships with key component suppliers, fabricators and contractors allow a totally integrated gas production facility on a sale basis from either the assembly shop or fully installed and operational basis right at your location. Producing the gas on site achieves the lowest cost, highest reliability and most flexible gas supply, thereby maximizing your production output and return on investment.
The Adsorptech proprietary VPSA process requires less energy than alternative oxygen systems and has no need for expensive high-quality seal water. For applications requiring up to 40 psig oxygen, Adsorptech's VPSA systems require no cooling water. Air contains 21% oxygen and the majority balance nitrogen. In Adsorptech's oxygen VPSA process, compressed air is fed into a vessel filled with molecular sieve at a positive pressure where the nitrogen is selectively adsorbed and the oxygen passes through as product. About when the nitrogen adsorption capacity is reached, a vacuum step removes the accumulated nitrogen and regenerates the sieve. Multiple vessels are used to produce a continuous supply of oxygen. Depending upon the oxygen application pressure need, an oxygen booster may be included.
