OXYGEN

At Green ASU, We produce Liquid Oxygen (O2) through Cryogenic air separation unit (ASU). This process is used to produce high purity oxygen or nitrogen at high volumes. Cryogenic separation is most effective method to produce high purity oxygen > 99.5% is required.

In normal conditions oxygen is a colourless, odourless and insipid gas; it condensates in a light blue liquid. 

The main applications of oxygen in order of importance are:

1) melting, refining and manufacture of steel and other metals;
2) manufacture of chemicals by controlled oxidation;
3) rocket propulsion;
4) medical and biological life support;
5) mining, production and manufacture of stone and glass products.

Oxygen is also used with fuel gases in gas welding, gas cutting, oxygen scarfing, flame cleaning, flame hardening, and flame straightening. In gas cutting, the oxygen must be of high quality to ensure a high cutting speed and a clean cut.

Green ASU technological team (SOL Group team) is supporting its customers not only with gas supplies. We share knowledge and know-how with respect to the application and spare time with customer to reach the desired result of such applications.

INDUSTRIAL Oxygen

Oxygen is used in diverse applications covering many industries, including:

Steel Manufacturing

To enrich air and increase combustion temperatures in the blast and open hearth furnaces; to raise steel temperatures and enhance recycling of scrap metal in electric arc furnaces and to replace coke as the combustible in steel making.

Chemical Processing

To alter the structure of feedstocks through oxidation, producing nitric acid, ethylene oxide, propylene oxide, vinyl chloride monomer and other building block chemicals; and to increase capacity and destruction efficiency of waste incinerators.

Pulp and Paper

To help manufacturers meet stringent environmental regulations in a variety of mill processes including delignification, bleaching, oxidative extraction, chemical recovery, white/black liquor oxidation and lime kiln enrichment.

Metal Production

To replace or enrich air, increasing combustion temperatures in ferrous and non-ferrous metals production; to create a hot flame in high-temperature welding torches used in cutting and welding.

Metal Fabrication

To support oxy-fuel cutting operations. Sometimes added in small quantities for shielding gases.

Glass Manufacturing

To enhance combustion in glass furnaces and forehearths, reducing nitrogen oxide (NOx) emissions.

Petroleum Recovery and Refining

To reduce viscosity and improve flow in oil and gas wells; to increase the capacity of fluid catalytic cracking plants as well as to facilitate the use of heavier feedstocks and to reduce sulfur emissions in refineries.

Health Services

To resuscitate or, in combination with other gases, to anesthetize but also essential to life-support systems used in emergencies or long-term treatment of patients with respiratory disorders.

Utilities

To convert coal to electricity for power generation.

Medical Oxygen

Industrial oxygen is not intended for human use. Solely medicinal oxygen that is tested to meet authorized specifications for its identity, purity and content and that was produced, stored and distributed following appropriate practices.

Medical Oxygen/Liquid Medical Oxygen is used during surgery, intensive care treatment, inhalation therapy, etc. High standards of purity and handling must be maintained. Oxygen is typically supplied to hospitals through bulk liquid deliveries, then distributed to usage points. It assists with respiratory problems for patients, saving lives and increasing patient comfort.

Many levels of the health systems need medical oxygen. The units in the health system
that use oxygen include:

  • Primary health care
  • General wards
  • Emergency transport
  • Delivery rooms
  • Operating theatre
  • Intensive care units (ICU)
  • Specialized hospitals
  • Outpatient units
