What is the difference between PSA and VSA?

VSA is short for Vacuum Swing Adsorption and PSA is short for Pressure Swing Adsorption. To understand the difference, you need to know that VSA uses a blower and a vacuum pump to separate the atmospheric air, whereas PSA uses 4 to 10 bar compressed air to do the air separation process.

What is VPSA oxygen?

Product Description. VPSA ( Vacuum pressure Swing Adsorption ) Oxygen gas Generators are based on well proven technology using Zeolite Molecular Sieves (ZMS) & Vacuum system for regeneration . In VPSA based Oxygen gas plants Regeneration process is dine with vacuum pumps, which ensures complete regeneration of ZMS.

Why vacuum swing adsorption technology is more effective?

PCI’s unique Vacuum Swing Adsorption (VSA) technology has several advantages over the more commonly used PSA process: Low operating pressure minimizes sieve (the sieve removes nitrogen from the air) dusting, because the pressure swing is at an order of magnitude lower, which also results in lower operating costs.

How does a VPSA work?

VPSA involves separating air into its constituent components by means of adsorption. In other words, the gas molecules bind with adsorbent material at different rates depending on the pressure. This allows operators to single out one particular gas from air.

How does a VPSA oxygen plant work?

What is PSA technology for oxygen generator?

Pressure swing adsorption (PSA) is the process by which ambient air passes through an internal filtration system (e.g. a molecular sieve [zeolite granules or membranes]), which has a large enough total surface area to separate nitrogen (N2) from the air, concentrating the remaining oxygen (O2) to a known purity.

How long does it take to install oxygen plant?

Dr Somanath Chatterjee , Medical Director of Prakriya Hospital said, “It takes manufacturers a couple of weeks to manufacture and ship it, while it may take only a few days for installation. However, the bigger challenge is that a majority of manufacturers have a backlog of orders ranging from four to six weeks.”
