Economic Benefits

  1. Return on Investment
    Cost of producing Oxygen is only the cost of power to operate the air compressor and hence, on average one can produce 1 m3 (or 1000 litres) per kW unit of electricity. Compared to purchase price of Oxygen for most customers, this is highly economical and hence, medical facilities all across the world recover their investment cost on PSA plant in less than 2-years on average. After the investment recovery, the medical facilities continue to enjoy benefits of low cost of production, thereby giving years and years of savings.
  2. Shield from market price increases of Oxygen
    – Gas merchants are highly dependent on market factors such as demand and supply and inflation, cost of power, cost of diesel / petrol (used to operate trucks for delivering cylinders). Hence, most medical facilities find themselves repeatedly negotiating price of purchased Oxygen and this is quite often a losing battle.
    – When operating a PSA Oxygen plant, customers are in control of the cost of produced Oxygen and since cost of power does not escalate easily, they are protected from unnecessary price shocks.

Environmentally friendly

To bring cylinders or liquid oxygen to, trucks and lorries running on diesel and petrol are used for long distances. Furthermore, the gas merchants themselves are likely trucking these from another gas production facility.

When oxygen is produced on-site at the medical facility, all the trucking is avoided and hence this provides a major environmental advantage, a major concern for everyone now.

Pay only for what you use

PSA oxygen plants produce the gas on-demand and only the amount actually used is produced. Hence, the medical facility only pays for what is consumed.

This is a major advantage compared to cylinders. Many times cylinders are either not filled accurately or returned with a significant amount of gas still inside. Hence, medical facilities, though paying for a full cylinder, do not actually consume all the gas they pay for.

Similarly, liquid oxygen in tanks are bulk-filled. There are losses due to liquid boil-offs and these are significant in hot climates where the boil-off rates may be as high as 2% per day. In a 15-day period, this means, the medical facility would have lost 30% of their purchased liquid oxygen they never used.

Total Independence

– Customers producing oxygen gas at their site become totally independent. This means no more hassles of repeatedly ordering cylinders or bulk oxygen through the procurement department.

– Concerns related to depletion of oxygen stock is eliminated as oxygen is always available on-demand from the oxygen plant.

– Many times, oxygen cylinders and bulk oxygen supplies are disrupted due to external factors such as labor strikes, transporter strikes and also inclement weather conditions such as rain and snow.

– Medical facilities outside of major cities find themselves at the mercy of the gas merchant and with an on-site oxygen plant, these worries are eliminated.

Safety

  1. Statutory approvals
    PSA medical oxygen plants from MVS do not require any statutory approvals for on-line supply of oxygen. In India, the PESO (Petroleum and Explosives Safety Organisation) does not need to approve or certify a PSA oxygen plant.
    – Bulk stock of cylinders or installation of liquid oxygen tank in most cases requires PESO approval from the CCoE (Chief Controller of Explosives) and a large perimeter needs to be created for safe storage of oxygen which is a highly combustible and flammable gas.
  2. Liquid oxygen carryover avoided
    – Medical facilities having liquid oxygen tank require a vaporiser. There is an ever-present concern that in case of vaporiser freezing or malfunction, liquid oxygen at cryogenic temperatures may get delivered to the patient which can be fatal.
    – In PSA oxygen plants, the oxygen is always in gaseous state and there is never a concern with liquid carryover.
  3. Occupational Health and Safety (OHS) rules
    – With cylinders, repeated operations like manual lifting, connecting, disconnecting cylinder require significant manpower on a regular basis. Bulk cylinders are extremely heavy and pose a health and safety risk on the personnel.
    Oxygen cylinders are pressurized to 150 bar or more and under pressure, they can leak large amount of gas in a short span of time, thereby creating a major safety and explosive problem.
    In PSA oxygen plants, the plants operate at only 5 bar and hence can never pose a high pressure gas risk. All manual handling is avoided as the plant is fully automatic and requires no operator.

Oxygen gas quality

– As proven and now accepted in pharmacopeias globally, oxygen at 93% ± 3% is widely accepted for all medical uses including anaesthesia and ventilators. PSA oxygen generation process only has inert gases such as argon and a small percentage of nitrogen in the balance impurities, these are harmless for patient consumption.

– In MVS PSA oxygen plants, the oxygen is continuously monitored in accordance with pharmacopeia norms.

– In oxygen cylinders, the purity varies significantly from cylinder to cylinder. Additionally, the CO and CO2 concentration in cylinders may be as high as 50 ppm. In a PSA oxygen plant, zeolites have a preferential affinity towards these and hence CO and CO2 in PSA oxygen will never exceed 1 ppm.

Back-up oxygen independence

In very remote areas or areas not served well by oxygen merchants, medical facilities can consider installing a cylinder filling backup oxygen compressor along with the PSA oxygen plant. This gives them complete independence and they can easily produce their own sufficient backup stock of oxygen to allow of uninterrupted oxygen supply in case of power outages, and, though a small time period, also times when plant is under maintenance. Please refer to various schemes we offer.
