Discount Price Oxygen Generator From Air - Industrial Vpsa Vacuum Pressure Swing Adsorption Oxygen Generator – Sihope

Air from a Blower is first cooled in an Aftercooler to reduce its moisture content and condensed moisture is separated in Moisture Separator. The cooled air passes through a Tower containing an a adsorbent which has the property to separate oxygen from the air resulting in a gas contains 93% oxygen (balance being argon & nitrogen) coming out as product gas. To ensure continuous flow of product gas, the other Tower is simultaneously regenerated by extracting the gases adsorbed in the previous cycle by a Vacuum Pump. Automatic operation is achieved by opening & closing the valves in a preset sequence by using a PLC. Cost of producing this oxygen is < 0.5 KWH at 0.2 bar pressure. There is a small increment in this due to power required for boosting pressure to required value, but this never exceeds 0.6 KWH/NM3. Overall cost of VPSA oxygen is Rs.5/- to 6/- per NM3 as against Rs. 10/- to 15/- for liquid O2.

Major application of this oxygen is for enrichment of combustion air used in fuel fired furnaces & kilns. Since the oxygen is produced onsite, it is a flexible, efficient and cost-effective technology that can help you save costs by lowering fuel usage, improve quality and also reduce emissions. Oxygen enrichment is beneficial in all high temp manufacturing processes used in glass, ferrous & non-ferrous metals, cement, ceramic tiles, sanitary ware, insulators, gasification of coal, coke, biomass, etc.

USES OF OXYGEN

• Oxygen is used to produce Ozone used for different applications (see Uses of Ozone)
• Direct oxygen injection in aerobic fermentation improves productivity of fermentation based pharma products, biofuels & biochemicals
• Using Oxygen for Delignification of Pulp gives significant operating cost advantages enhances yield in bleached pulp production and eliminates use of chlorine based chemicals.
• Oxygen is used as reactant in many chemical oxidation reactions.
• In stainless steel and alloy steel manufacture, decarburization and desulfurization is effectively done by oxygen in conjunction with nitrogen & argon.
• By adding Oxygen to raise the level of dissolved oxygen in Waste water treatment results in reduced odours & increased aeration efficiency.
• Introducing oxygen into metal production operations in BOF, EAF and Cupolas will result in improved productivity, lower costs and reduced CO emission.
