Alkanolamines for acid gas scrubbing

Alkanolamines are chemical compounds that contain both hydroxyl (-OH) and amino (-NH2, -NHR, and -NR2) functionality. Commonly used alkolalamines such as monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) are produced by reacting ethylene oxide with ammonia.

These alkanolamines are widely used in a multitude of applications ranging from consumer cosmetic formulations and cleaning products to industrial applications like cement processing, corrosion inhibition, metalworking, as well as carbon dioxide (CO2) and hydrogen sulfide (H2S) gas scrubbing. INVISTA Dytek® amines provide unique starting points for design of new specialty alkanolamines.

Alkanolamines for acid gas scrubbing

Farms and municipal landfills produce vast amounts of methane from naturally-occurring biodegradation. The methane in this biogas has fuel value but is often wasted because it contains undesirable acid gases including hydrogen sulfide and carbon dioxide.

Gas-scrubbing technology using new alkanolamines prepared from Dytek® HMI and glycidol from bio-based glycerol is being developed that may offer a cost-effective way to capture previously wasted biogas.
