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.
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.
– 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.
– 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.
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.
