VPSA
If you are looking for oxygen generator at moderately lower generating pressure with lower electrical energy consumption then VPSA Oxygen Plant is for you. Brise Chemicals is the best Vpsa oxygen Plant, Manufacturer.
VPSA oxygen Generator process utilized by BRISE CHEMICALS plants is a method of separating air into its two principal components—nitrogen and oxygen— using adsorption technology at moderately low pressure (8 PSIG) by air-blower system. The oxygen at 90–93 Vol % purity is provided to the customer as a product, and the impure nitrogen combined with any water and carbon dioxide is vented back to the atmosphere and further sucked out with the help of vacuum pump/ blowers system.
There are three main phases of the pressure swing adsorption process:
- 1. Adsorption: The pre-treated air passes into a vessel containing zeolites to remove any moisture and/or CO2 and adsorbs the nitrogen while oxygen passes through the vessel outlet. Before the adsorption capability of the zeolite is exhausted the adsorption process is interrupted. the top of the column. This takes place until the adsorber saturation.
- 2. Deadsorption: The saturated zeolite is regenerated (i. e. the adsorbed gases released) by means of pressure reduction below adsorption pressure. This is achieved by a dry running vacuum pump. The resulting off gas is vented to atmosphere. To maintain a continuous flow of oxygen supply a surge tank is installed.
- 3. Repressurization: The adsorber is repressurized with pure gas and is now ready to receive more feed gas to start the process over.
