Project Description

Arian gas company  activities in  supplying  different  kinds  of  industrial, laboratory, and medical gases. Arian gas supply  imported carbon monoxide gas with 99.5%, 99.9% purity in 50 lit cylinder

  • Carbon monoxide (CO)
  1. Carbon monoxide (CO) gas is formed from the combination of a carbon atom with an oxygen atom. Not only flammable, it is also very hazardous since it is very toxic and odorless. It cannot sustain life and is produced, among other things, from incomplete combustion due to lack of oxygen. It can therefore cause domestic accidents if heating systems are poorly maintained. It is produced on a large scale in industry, in combination with hydrogen, by reforming hydrocarbons, generally natural gas. It is used in large quantities to produce various intermediary organic chemicals, such as acetic acids, isocyanates, formic acid, and also certain polymers such as polycarbonates and polyketones.
  • Main applications
  1. Industries  Applications
  2. Chemicals

 

  1. Carbon monoxide and synthesis gas are the raw materials in the polycarbonate, polyurethane and oxy-alcohol manufacture based on SMR and ATR processes or on partial oxidation.
  2. Carbon monoxide is also used in the manufacturing of metal carbonyls.
  •   Laboratories & analysis
  • Carbon monoxide is used in calibration gas mixtures for petrochemical industry; environmental emission monitoring, industrial hygiene monitors and trace impurity analyzers.

  • Material compatibility

 

  1. Air Liquide has assembled data on the compatibility of gases with materials to assist you in evaluating which products to use for a gas system. Although the information has been compiled from what Air Liquide believes are reliable sources (International Standards: Compatibility of cylinder and valve materials with gas content; Part 1: ISO 11114-1 (Jul 1998), Part 2: ISO 11114-2 (Mar 2001)), it must be used with extreme caution. No raw data such as this can cover all conditions of concentration, temperature, humidity, impurities and aeration. It is therefore recommended that this table is used to choose possible materials and then more extensive investigation and testing is carried out under the specific conditions of use. The collected data mainly concern high pressure applications at ambiant temperature and the safety aspect of material compatibity rather than the quality aspect
