CO-Carbon Monoxide
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
High purity carbon monoxide is produced from lower purity material by a combination of purification techniques including molecular sieve and cryogenic fractional distillation.
Main applications
1. Chemicals
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 Carbon monoxide is also used in the manufacturing of metal carbonyls.
2. Laboratories & analysis
Carbon monoxide is used in calibration gas mixtures for petrochemical industry; environmental emission monitoring, industrial hygiene monitors and trace impurity analyzers.
