Types of Oxygen And Nitrogen Generator

Types of Oxygen Generators

Pressure Swing Adsorption Oxygen Generator
Pressure Swing Adsorption (PSA) is the most common method of producing oxygen at an industrial scale. PSA generators separate nitrogen from ambient air inside a pressurized tank filled with Zeolite.

Membrane Oxygen Generator
Membrane oxygen generators us a compressed air stream passed through semi-permeable materials that allow for the passage of specific molecules. Under pressure, smaller oxygen molecules pass through the membrane, filtered out and collected leaving a stream of nitrogen flowing out the opposite end of the membrane.

Chemical Oxygen Generator
A chemical oxygen generator is a device that releases oxygen by a chemical reaction. A container of inorganic salts called “superoxides” or sodium chlorate are ignited.

Nitrogen Generator Applications

Electronics Manufacturing
Nitrogen is primarily used for selective and wave soldering processes to improve product quality, reduce dross and lower maintenance costs.

Food & Beverage
Onsite nitrogen generating systems can save food packagers hundreds of thousands of dollars in nitrogen costs per year.

Pharmaceuticals
Use nitrogen for tablet press purging, freeze drying, liquid medications, and powder transport in pharmaceutical processing and storage.

Chemical Processing
Use nitrogen as an inert gas for blanketing chemical storage tanks and safe transfer of flammable chemicals. Prevents reaction with air.

Metals Manufacturing
Purge furnaces, casting molds, and other processes with nitrogen for improved quality of metals and less oxidation.

Oxygen Generator Applications

Aquaculture
Onsite oxygen generators are ideal for aquaculture. They enable fish farms to dissolve oxygen into a variety of tank sizes, which helps to boost stocking densities and raise healthier fish.

Water Treatment and Purification
Offensive odours and bacteria in sewage water are a challenge to eradicate with inadequate levels of purification, which is why onsite oxygen tanks are so valuable to this industry.

Gold Mining
To boost gold recovery and reduce your mine’s operating costs, onsite oxygen generation is the solution. It increases the level of dissolved oxygen in your mine’s leaching process without the added costs of purchasing liquid oxygen and having it delivered to your facility.

Pulp and Paper Manufacturing
Delignification is the process of extracting lignin from the plant material in one of the steps required to make paper from trees. Large amounts of oxygen are required in this process, as well as several other later steps in pulp and paper manufacturing.

FAQ

Q: What do oxygen and nitrogen make up?

A: The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.

Q: What does a nitrogen generator do?

A: Essentially, this is how a nitrogen generator works: it separates nitrogen molecules from the oxygen molecules within compressed air, resulting in a purified supply of nitrogen.

Q: What does nitrogen and oxygen produce?

A: NO x gases are usually produced from the reaction between nitrogen and oxygen during combustion of fuels, such as hydrocarbons, in air; especially at high temperatures, such as in car engines.

Q: How much air is needed to produce nitrogen?

A: Air: N2 ratio is 3.4:1. Therefore 30.9 x 3.4 = 105m3/h air inlet flow requirement to generator. Selected from dryer table a OFAS HL 70 @ -40°C pdp at 7 bar(g) inlet pressure will flow up to 120m3/h outlet with 26.8m3/h purge flow.

Q: How long does a nitrogen generator last?

A: What is the life expectancy of a nitrogen generator? Just like any piece of equipment, everything boils down to preventative maintenance. If routine maintenance is followed the systems should last for well over 15 years.
