VPSACustom-Engineered "Vacuum Pressure Swing Adsorption" (VPSA) Oxygen Systems

Maruti corporation is the leading manufacturer of VPSA Oxygen gas Plants. We are having a great experience of costom made VPSA (Vacuum Pressure Swing Adsorption system) and PSA (Pressure Swing Adsorption) custom-made Vacuum Pressure Swing Adsorption (VPSA) Oxygen Systems designed to the specific requirements, with capacities from 3,600 SCFH (100 Nm3/hr) to 53000 SCFH (1500 Nm3/hr). Highly -efficient, 2-4 bed VPSA oxygen process (4 beds for higher capacity requirement). these technology offers extremely low energy consumption, on stream efficiency of 99%, easy operation, and long-term equipment life.

VPSA plant working Principle:

in This process consists of 2 or 4 beds filled with Molecular Sieves. These cycle alternately in Production and in Regeneration. Feed air pressure is supplied with air blowers at 0.25 to 0.5 Bar, which gives Oxygen production at 0.20 to 0.45 Bar. Regeneration of Molecular sieves is achived by a highly efficient water cooled Vacuum pump at 0.6 Bar pressure. in a result Product Oxygen gas purity is achived around 90 to 95% The waste gas is 80-85% Nitrogen and 11-15% Oxygen which is vented to atmosphere via discharge silencer.Speciallized X type molecular sieves are used as adsorption agents when producing oxygen from the air by adsorptive means.They adsorb nitrogen, water vapor, and carbon dioxide to a much higher degree than oxygen. This means that a product flow comprising essentially only oxygen and argon can be removed from the process air being passed through the adsorption bed. The compressed air enters the adsorbers. The nitrogen is adsorbed while the oxygen product leaves the vessels. After a certain time the adsorption is interrupted and evacuation by a vacuum pump desorbs the enriched nitrogen. The oxygen product flow is compressed to the required discharge pressure, if required.

We Work on SCADA and DCS Systems :

The term SCADA usually refers to centralized systems which monitor and control entire sites, or complexes of systems spread out over large areas (anything from an industrial plant to a nation). Most control actions are performed automatically by RTUs or by PLCs. Host control functions are usually restricted to basic overriding or supervisory level intervention. For example, a PLC may control the flow of cooling water through part of an industrial process, but the SCADA system may allow operators to change the set points for the flow, and enable alarm conditions, such as loss of flow and high temperature, to be displayed and recorded. The feedback control loop passes through the RTU or PLC, while the SCADA system monitors the overall performance of the loop.

PSA Oxygen

Using this technology, we produce oxygen gas plants that are highly economical and require low maintenance and produce the desired results in a hassle-free manner.

PSA Nitrogen

PSA Nitrogen N2 Gas Generator Equipment is an Inert Gas Atmosphere Generator & incorporates Two sets of columns filled with Carbon Molecular Sieves CMS.

Air Dryer

Our air dryers are designed for a long lifetime of reliable operation. Using only compressed air as a purge, they provide you with the clean, dry air you needed to extend the life of your equipment.

Ammomia Cracker

An ammonia cracker or hydrogen generator is used for the production of forming gas. Hydrogen and Nitrogen are generated in a cost effective way in a volume ratio of 3:1 or in a weight ratio of 14:3.
