How an Oxygen Generator is Use in Manufacturing Companies
Oxygen Use in Industry
Adding oxygen to a process allows better control of heating patterns, higher furnace efficiency (for lower fuel consumption), and reduced particulate and NOx emissions. It is used with fuel gases to improve gas welding, gas cutting, oxygen gouging, flame cleaning, flame hardening and flame straightening. O2 is a raw material in several oxidation procedures and is also used to regenerate catalysts.
How does an Oxygen Generator Work?
About 21% of the air we breathe is oxygen. Industrial oxygen is generate by separating oxygen molecules from other molecules in a clean, dry compressed air stream. Pressure Swing Adsorption (PSA) is a simple, trustworthy and cost-effective technology that provides a continuous flow of high capacity oxygen with the desired purity level. Adsorption occurs when atoms, ions, or molecules of a substance (compressed air in this case) adhere to the surface of an adsorbent. PSA machinery isolates oxygen molecules from other molecules (nitrogen, CO 2, water vapour and trace gases). To allow high purity oxygen to leave the generator. The process occurs in two independent pressure tanks (tower A and tower B). Each includes a carbon molecular sieve, which alternates between separation and regeneration processes.
Advantages of on-Site Production
Internal oxygen generation offers many critical advantages over supplying oxygen from cylinders or tanks. For example, it ensures the continuous availability of O2, eliminating the risk of a production stoppage due to supply problems or supplier shortages. It also avoids constant replenishment order processing and supply costs associated with bottled O2. It also eliminates space and special handling requirements for full oxygen cylinders in inventory and empty cylinders waiting to be pick up, refilled and replenished.
Industries that use oxygen
A reliable supply of oxygen is crucial to production operations in many industries. Steel, Food, and beverage Pharmaceuticals, Plastic injection moulding, Electronics, Laser cutting Semiconductors. Gold and silver mining/extraction, Oxy-fuel combustion, Chemicals, Pulp and paper heat treatment of metals Cable and fibre optics Glass Fire prevention, Fish farming Wastewater treatment Ask an air system professional about the best solution to generate O2 internally.
What is Industrial Oxygen, and how is it Produce?
Industrial oxygen has, in principle, the same components as medicinal O2. Since, in the manufacture of both, the same raw material is process air. However, for the uses indicated by the Peruvian technical standard NTP 311.113:1978. The percentage of O2 must be equal to or greater than 99.5%.
It is usually produce by O2 plants operating air separation units (ASU ) by distillation at shallow temperatures. The air undergoes impurity removal, compression, expansion and cooling stages to reach temperatures low enough for nitrogen (P. eb = -195.8°C) to separate as vapour and O2 (P. eb = -195.8°C). = -183°C) as a liquid in a cryogenic distillation column. The nitrogen is typically purge, while the liquid O2 produce can store and re-gasified. These processes can designed and optimized by computer.
How can I be Sure a Cylinder has Oxygen and in the Percentage that it Should have?
The presence of oxygen in a gaseous sample can be recognize due to the colour change of an alkaline. Aqueous solution of pyrogallol from colourless to brown when said sample bubbles into it due to the reaction between O2 and pyrogallol. This same principle can be use to determine the percentage of O2 in a volume of the gaseous sample. Although today, safer analytical methods are used, such as the one based on the oxidation of copper in ammoniacal ammonium chloride solutions. Electrochemical sensors are also possible if they are correctly calibrated and their electrical signal compensates for changes in gas temperature.
Oxygen is an oxidizing gas; it facilitates the combustion of flammable materials. Therefore, extreme precautions must taken against possible leaks, and adequate protective equipment must be use to deal with them. A good practice is to avoid the proximity of all types of flammable material, ignition sources, and direct sunlight. Also, the cylinders must be adequately secure to prevent them from being knock over, and the pressure regulating valve protect from impact.
Oxygen for medical and industrial use, he explain, is obtain from the air in the atmosphere. But to obtain it and store it in tanks, it goes through several processes. Which consist of compressing, filtering and cooling it; In this stage, the separation between O2 and nitrogen is make.
