What is Carbon Monoxide (CO)?

• Carbon monoxide is a colorless, odorless, toxic, and flammable gas.
• Liquid carbon monoxide is a cryogenic fluid.
• Carbon monoxide can be found at -192 ⁰C and atmospheric pressure.
• Carbon monoxide is lethal in less than an hour if it has a concentration of more than 4% in the air.
• Inhalation of high concentrations of this gas causes sudden and asymptomatic fainting.

Available grades:

• Carbon monoxide is available in various grades from %98 to %99.99.
• Existing grades of carbon monoxide are:

% 98.5,% 99,% 99.5,% 99.99

Tanks and maintenance:

• Carbon monoxide is transported in cylinders, trailer tubes, and cryogenic bulk tanks.

Compatible and incompatible materials:

1. Ordinary steels and metals are compatible with dry, sulfur-free carbon monoxide.
2. The presence of carbon dioxide impurities and moisture in carbon monoxide increases the corrosive properties of these gases.
3. High-pressure plant equipment is usually made of copper.
4. Copper is resistant to carbon monoxide.
5. High-grade chromium steels are highly resistant to corrosion of carbon monoxide with sulfur impurities.
6. Butyl rubber and chloro-fluoro-carbon polymers such as VITON should not be used due to swelling in carbon monoxide.
