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:

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

GAS

S – Satisfactory for use with the intended gas
C – Conditional. May be incompatible under some circumstances or conditions Contact your Praxair representative for additional information
U – Unsatisfactory for use with the intended gas
I – Insufficient data available to determine compatibility with the intended gas
O – All nonmetalic, even those considered compatible, may be ignitable in oxygen enriched environments or in other oxidizing gases. Successful
use depends upon oxygen purity, pressure, temperature, cleanliness and elimination of ignition mechanisms. Please contact your Praxair
