Oxygen is one of the most vital industrial and medical gases, essential in both life-saving treatments and critical manufacturing processes. Traditionally, industries and hospitals have relied on bulk oxygen supply—delivered in cylinders or cryogenic liquid form. However, the growing demand for oxygen, coupled with supply chain challenges and the push for cost-effective, efficient operations, has sparked a major shift toward on-site oxygen generation.

In this blog, we’ll explore why on-site oxygen generation is transforming the healthcare and manufacturing sectors, the technologies involved, and how it delivers operational, economic, and safety advantages.

🔍 What is On-Site Oxygen Generation?

On-site oxygen generation involves producing oxygen gas directly at the point of use, eliminating the need for transportation and storage of cylinders or liquid oxygen tanks. This is achieved using two main technologies:

1️. PSA (Pressure Swing Adsorption) Technology

How it works: PSA systems separate oxygen from atmospheric air by using molecular sieves that adsorb nitrogen under pressure, allowing oxygen to pass through.
Oxygen Purity: Typically 90% to 95%
Applications: Widely used in hospitals, metal cutting, glass manufacturing, ozone generation, and water treatment.

2️. VSA (Vacuum Swing Adsorption) and VPSA (Vacuum Pressure Swing Adsorption)

How it works: Similar to PSA but uses a vacuum during the desorption cycle, improving energy efficiency for large-scale oxygen production.
Best suited for: High-volume oxygen demands in steel, cement, and chemical plants.

🏥 Why On-Site Oxygen is Crucial for the Healthcare Sector

✅ 1. Continuous, Reliable Oxygen Supply

In hospitals, oxygen is a life-critical gas used for:

Respiratory support (ventilators, oxygen therapy)
Surgical anesthesia
Emergency treatment
Intensive care and neonatal care

On-site generation ensures uninterrupted oxygen availability, which is especially critical during surges in demand—as witnessed during the COVID-19 pandemic.

⚠ During global emergencies, supply chains often collapse. On-site oxygen plants eliminate this risk by enabling hospitals to be self-reliant.

✅ 2. Cost Savings

Hospitals can significantly reduce recurring expenses:

No more bulk oxygen purchases
Elimination of cylinder logistics and handling costs
Reduced labor and inventory management

✅ 3. Enhanced Safety

Cylinders and liquid oxygen storage pose fire and explosion risks. On-site systems produce oxygen as needed, minimizing stored volumes and reducing hazards.

✅ 4. Scalability and Automation

Modern on-site oxygen plants, like HGPL’s PSA-based systems, come with automated controls, remote monitoring, and easy scalability. Hospitals can start small and expand as needed.

🏭 On-Site Oxygen in Manufacturing: Driving Efficiency & Performance

In the industrial world, oxygen is a process-enhancing gas used to improve combustion efficiency, increase reaction rates, and maintain product quality. Here’s how on-site generation transforms manufacturing operations:

✅ 1. Enhanced Process Efficiency

Metal cutting and welding: Higher oxygen purity improves flame temperature and cut quality.
Glass and ceramics: Oxygen boosts combustion temperatures, improving melting efficiency and product uniformity.
Water treatment: Oxygen supports ozone generation and aerobic digestion processes.

✅ 2. Reduced Operating Costs

Avoid cylinder rental, delivery charges, and wastage from unused gas in cylinders.
Lower energy consumption per Nm³ compared to liquefied oxygen.

💡 Many industries experience 30–60% savings in oxygen-related costs after switching to on-site generation.

✅ 3. Reliable Oxygen Supply

Eliminate supply chain dependencies and production downtime due to delivery delays or oxygen shortages.
Continuous oxygen supply aligns with just-in-time manufacturing practices.

✅ 4. Custom Purity & Flow Rates

PSA oxygen systems can be tailored to deliver exact purity and flow rates needed for specific processes.
Avoid overpaying for ultra-high purity oxygen when standard purity suffices.

Balaji Speciality Chemicals Limited (BSCL), a subsidiary of Balaji Amines Limited, has selected Hydrogen Gentech Private Limited (HGPL) to design, engineer, manufacture, supply, and commission its Hydrogen Purification Unit. The unit will generate high-purity hydrogen using the Methanol cracking process.

To produce high-purity hydrogen, the H2 Purification process technology involves a process study of the composition of mixed gas received at the outlet of the Methanol cracking reactor. This study determines the suitable adsorbents required to remove each impurity via adsorption-based removal and achieve the desired purity level of the hydrogen product.

The PSA-based hydrogen purification system will have five towers working cyclically in different phases of H2 generation and tower regeneration stages. Each of the five towers will cyclically work in high purity H2 generation mode while the other four towers operate in different stages of pressurization, depressurization, equalization, and regeneration modes. This design allows for the continuous generation of pure H2.

The adsorber tower for the PSA-based hydrogen purification system will consist of a customized multi-layered, molecular sieve-based adsorption bed system based on the type and quantum of impurities present in the mixed gas streams. The design will ensure that high-purity H2 is generated while minimizing the loss of any H2 during the adsorption process.

HGPL’s scope of work includes detailed engineering, procurement, manufacturing, supply, erection supervision and commissioning, Performance Guarantee Test Run (PGTR), and training. The PGTR will ensure that the unit performs as per the specified parameters and guarantees the performance of the system.

The Hydrogen Purification Unit will be fully automatic, with a control system that includes all safety measures. The PSA-based hydrogen purification technology is a popular route to establish small and medium capacity H2 generation plants, making HGPL a fast-emerging key technology player in India in the field of Hydrogen generation and Purification systems using the Methanol cracking process.
