What is Pressure Swing Absorption Technology in Oxygen Generators?

1. Introduction

PSA technology is a form of oxygen-generating technology that uses the inherent energy of a catalytic reaction to transform carbon dioxide into a more efficient form, which is transported through the air in the form of gas, where it can be used as a true liquid fuel.
PSA technology is based on applying an “on-site” pressure swing adsorption (PSA) process to CO 2 generated by the electrolysis of hydrogen and water. The CO 2 /H 2 /water reaction, when applied at high pressure, provides an attractive source of chemical energy. However, this process is limited by its capital cost and environmental impact.
The PSA process does not only eliminate these constraints but also offers very large energy output at a low cost and without any waste heat or pollutant emissions. As such, PSA technology could provide an attractive alternative for a wide range of applications such as power generation through electrolysis or renewable hydrogen production using renewable electricity.

2. What is PSA oxygen technology?

PSA technology is a new type of compressor-based oxygen generator. In essence, it is an integrated system that uses the heat generated by an oxygen generator, which can be either an on-site or off-site unit, for the generation of up to 1,400 liters (200 US GPM) of oxygen per minute from ambient air.
Most oxygen generators use large (and expensive) compressors that are designed to produce one or two liters (or less) of oxygen per minute. In contrast, PSA technology has been developed over years to generate up to 120 liters (60 US GPM) of oxygen per minute from a single 2.5-tonne (4,000 kg) boiler. This means that PSA technology is capable of delivering a high-quality and reliable supply of air at rock-bottom prices.
Psa technology is no longer restricted only to the industrial sector and is now used in many households and by consumers all over the world. As these technologies become more widespread they are going to become more and more competitive with conventional generators and compressors, while reducing unit costs and providing better power quality than existing compressors in many applications.

3. What are the benefits of PSA oxygen generators?

Pressure Swing Absorption technology (PSA) oxygen generators deliver a high-capacity flow at the purity you need. Suitable for a wide range of applications.
Pressure Swing Absorption technology (PSA) oxygen generators are the first portable pure oxygen generators to offer a very high capacity flow – up to 1000 l/min in the largest sizes. This unique feature is perfect for controlling water, waste, and oils. PSA oxygen generators deliver an extremely pure carbon dioxide gas that is highly stable and environmentally friendly, which makes them ideal for hospitals, schools, and homes. Many other pure oxygen generators use corrosive metals like lead or cadmium to produce the same pure carbon dioxide. But because PSA oxygen generators use a non-corrosive metal like copper or zinc instead of lead, they are safe and easy to maintain.

4. How does PSA oxygen technology work?

Pressure Swing Absorption Technology (PSA) has been around for quite a while, but there's still a lot of confusion about how it works. Here's a quick and easy explanation of how it works.
Oxygen technology has always been important to oxygen generators. They are typically large, long-lasting machines that generate up to twenty cubic feet of pure oxygen per hour. In addition, there are small, portable generators that can be used in many different environments and applications. PSA oxygen technology was developed to enable the on-site generation of pure oxygen at low pressure.
The difference between the two types of systems is in their design. Portable generators are more efficient than stationary ones because they have more surface area, which means they produce more oxygen per unit volume than a stationary machine. However, if you're running a portable generator in an enclosed environment with reduced air pressure you aren't generating as much pure oxygen per unit time as you would with a stationary machine because the pressure swing is not nearly deep enough to achieve the same low-pressure flow rate as needed for on-site use. This is where PSA enters the picture: PSA systems feature a switch that allows you to change the pressure swing on demand (and therefore your flow rate) from off-air to on-air so that your device can efficiently transfer pure oxygen from the ambient air into your unit without having it swell or bulge as it does when operating at atmospheric pressure (atmospheric pressure is approximately 760 mmHg).
When you're using an O2 generator correctly, it will provide approximately 11% of its listed capacity—which we call "on-site" capacity—in as little as 10 minutes; however, under certain circumstances, you may need more than 12% on-site capacity from time to time (for example when venting methane or natural gas). These conditions can occur when working with heavy or unruly mixtures containing corrosive chemicals or explosive fumes and gases such as methane gas and carbon dioxide gas (also known as CO2).
If these conditions occur over an extended period of time, your device may require frequent servicing by removing its battery and replacing it with a fresh one every couple of hours or so because its internal battery power declines when operating at high pressures for prolonged periods without being recharged (this happens even though your device has been designed so that recharging requires very little power loss compared with other kinds of batteries which have minimal power loss when charging).

5. What are the applications of PSA oxygen generators?

Pressure Swing Absorption or PSA is a technology that allows continuously variable flow rates with minimal pressure drop. On-site PSA oxygen generators deliver a high-capacity flow at the purity you need. Suitable for a wide range of applications. It has been adopted for the production of oxygen in manufacturing and chemical process industries. As well as for the production of liquid oxygen gas for aerospace, marine, and industrial applications. With Pressure Swing Absorption technology (PSA).
