1. Introduction

The oxygen requirement of different industries is increasing day by day. For this reason, optimum production technology is needed. With a VPSA oxygen plant you will get high capacity oxygen with less energy consumption. What is more you will keep your industry running uninterruptedly. Since minimizing operating cost is important, VPSA system have good market prospects.

At Nanjing Bangwin Gas we supply oxygen generation technology to industries around the globe. Industries can stabilize their oxygen supply and efficiency with our help.

l Cryogenic Air Separation Plant

2. What Is a VPSA Oxygen Plant

VPSA stands for Vacuum Pressure Swing Adsorption technology. VPSA oxygen plants separate oxygen from air by way of molecular sieve adsorption. However, unlike PSA technology, it works in lower pressure with vacuum assistance.

So, VPSA Oxygen Plants are ideal for medium and large scale industries which require continuous oxygen flow at lower operating costs.

3. Working Principle

The working principle of VPSA oxygen plant can be explained in the following points.

Adsorption:

Filtered ambient air is input to the system with the help of a blower at low pressure.

Absorption of nitrogen from air:

Nitrogen particles are absorbed by the molecular sieve. And oxygen is obtained as product gas.

Vacuum:

Vacuum pump is used to regenerate the adsorbed nitrogen from the sieve.

Sequential adsorption towers:

As one tower is in the process of adsorption, the other tower is undergoing vacuum regeneration. Thus oxygen generation is uninterrupted.

Low maintenance VPSA oxygen plants allow smooth and efficient separation of oxygen from nitrogen.

4. Key Equipments of VPSA Oxygen Plant

5. VPSA vs PSA vs Cryogenic Air Separation

Different oxygen generation technologies serve different capacities.

Therefore, a VPSA oxygen plant balances efficiency and production scale.

6. Benefits Of VPSA Oxygen Plants

The benefit of VPSA oxygen plants are listed below.

Electricity Saving

Lower pressure reduces the amount of electricity used.

Large Capacity

Facilities produce large amounts of oxygen continuously.

Stable

Usually between 90% ~95%.

Lower T.O.C

Low power consumption reduces total cost of ownership.

Long lifetime

Low mechanical load ensures long lifetime of adsorbent material.

Industrial plants using VPSA oxygen plants don’t rely on liquid oxygen suppliers and have them installed on-site for these reasons.

7. Uses

These types of plants can service many different industries.

l Typical Uses

l Steel industry and metallurgy

l Glass industry

l Non-ferrous metals

l Chemical industry

l Wastewater treatment plants

l Ozone generators

Many industrial processes can perform better with a stable supply of oxygen.
