VPSA Oxygen Generators

Optimized Molecular Sieve Solutions
For VPSA Oxygen Generators

VPSA (Vacuum Pressure Swing Adsorption) oxygen generators are advanced industrial gas separation systems, delivering efficient, sustainable oxygen supply solutions across medical, industrial, chemical, and environmental sectors. The process utilizes zeolite molecular sieve beds to selectively adsorb nitrogen from compressed air, producing high-purity oxygen. When saturated, the sieves regenerate under vacuum pressure, releasing nitrogen and ensuring continuous oxygen generation.
 
With over 26 years of expertise in molecular sieve technology, we specialize in optimizing VPSA oxygen generation systems. Our advanced lithium-based X-type zeolite sieve beds maximize operational efficiency through superior nitrogen selectivity, high adsorption capacity, and exceptional durability. You’ll achieve enhanced system reliability and reduced operational costs, ensuring long-term value for your oxygen production.

Glencore’s Southeast Asian Subsidiary’s Adsorbent Replacement

Jalon successfully upgraded adsorbents for Glencore Southeast Asia Subsidiary’s VPSA oxygen generation system, improving the oxygen concentration from 37.7% to 91.7%. With our technical expertise, we delivered results that significantly surpassed the client’s original expectations.

Project Overview

Installed in 2012, the VPSA-2 equipment at Glencore's Southeast Asia Subsidiary was designed for a capacity of 4000 Nm³/h with an oxygen purity of 89%-91%. However, since October 2018, its oxygen purity has gradually declined to 37.7%. The decline in oxygen purity was attributed to the deterioration of the adsorbent's performance, as determined by analysis.

Jalon’s Solution

To address this, approximately 84.278 tons of adsorbent were replaced in the VPSA-2 system. All required materials, including activated alumina, molecular sieves, ceramic balls, mesh screens and subsequent loading technical services for this project are provided by Luoyang Jalon Micro-Nano New Materials Co., Ltd.

Frequently Asked Questions

VPSA (Vacuum Pressure Swing Adsorption) is an advanced gas separation technology used primarily for the economical and energy-efficient production of oxygen. In VPSA systems, ambient air is drawn into a vessel filled with selective adsorbent materials—such as molecular sieves—that preferentially adsorb nitrogen, carbon dioxide, moisture, and other impurities, leaving behind high-purity oxygen.
The oxygen purity achieved using VPSA technology typically ranges ranges from 90% to 95%, which is well-suited for most industrial applications. The exact purity can be customized based on the application requirements and system design.
Industries that commonly use VPSA oxygen generators include steelmaking, glass production, chemical manufacturing, water treatment, pulp and paper, mining, and energy sectors. These industries rely on VPSA for its efficiency, reliability, and consistent oxygen supply.

The primary difference between PSA and VPSA lies in how they regenerate the adsorbent materials during the desorption process. PSA systems release pressure to regenerate the adsorbents, while VPSA systems use a vacuum, which is more energy-efficient and enhances system performance.

PSA is typically used for smaller-scale applications with moderate oxygen demand, offering a compact design suitable for moderate gas flows. In comparison, VPSA is better suited for larger-scale, continuous applications requiring high oxygen demand, as it utilizes larger systems optimized for higher gas flows.

From an energy and cost perspective, PSA systems tend to consume more energy and have higher operating costs for large-scale applications. In contrast, VPSA systems are more energy-efficient due to vacuum regeneration, resulting in lower operating costs, making them ideal for industrial-scale use.
