Adsorption is defined as the affinity of a fluid for a solid surface. Using the differential affinities of several components of a gas mixture (such as air) it is possible to separate the various components. That, essentially, is the principle used by a PSA oxygen plant.
Such a plant can have different capacities to generate oxygen. It employs a technology that absorbs nitrogen from the ambient air to concentrate oxygen and supply it to hospitals or industry, as the case may be. The oxygen thus generated can be supplied directly to the place of use through a dedicated pipe or compressed to fill cylinders.
Medical-grade oxygen has an oxygen concentration between 90% and 96%. The rest is mainly argon and nitrogen.
They operate at temperatures close to the environment and use specific adsorbent materials such as zeolites, activated carbon, molecular sieves, etc., to trap oxygen at high pressure. While the oxygen produced by these plants is thought to be less pure than the liquid oxygen derived from cryogenic technology, outrage in the country is currently centered on the debate over whether these plants could have helped alleviate the current medical oxygen crisis.
The first advantage is that the hospital has a captive plant that can generate all the oxygen it needs, eliminating the need for cylinders, etc.
Cylinder handling also has a safety aspect, as high-pressure oxygen is highly flammable. Several fires at Covid-19 hospitals across the country in recent days have been grim reminders of those risks. The plant can also provide you with some cushioning during periods of peak demand. It's not an expensive technology.
But what also works great for hospitals is the fact that PSA is "clean technology." The raw material it uses is ambient air. It also occupies a very limited space; the maximum area occupied by a PSA oxygen plant is about 7 feet/9 feet/7 feet. It only takes a few weeks to get a plant up and running and there are at least 25 suppliers in the country that can supply between 2 and 20 plants per month.
The oxygen generator produces gas at a very low pressure and also maintains only a small amount of backup in certified storage tanks. Therefore, the risk of oxygen combustion is minimized. In contrast, oxygen cylinders have a large amount of oxygen in a cylinder, compressed at a very high pressure. Constant handling of cylinders presents human risks and the risk of repeated stress failures, which leads to very risky situations. By installing an oxygen generator on site, the handling of the cylinders is drastically reduced, and as a result, the medical facility improves their safety.
Oxygen generators take up very little space. In many cases, the space for the storage of cylinders and the collector is also sufficient for the installation of the oxygen plant. If a larger hospital is a liquid oxygen tank, large amounts of free space are wasted due to legal regulations. This space can be recovered by changing to an oxygen plant on site.
Cylinders require a constant order. Once the cylinders are received, it is necessary to weigh them and check the quantities. All of this administrative burden is removed with our on-site oxygen generator.
The biggest concern of a hospital administrator and a biomedical engineer is running out of oxygen cylinders at critical times. With an oxygen generator in place, gas is produced automatically 24/7 and with a carefully designed backup system, the hospital no longer has to worry about being empty.
With an on-site oxygen generator, the cost of purchasing liquid oxygen or handling cylinders can be skipped
Our oxygen generating systems are designed for continuous operation. Local oxygen generation avoids dependence on third parties for oxygen supply.
