Genosorb® 300

Absorption fluid

Edition Date :
August 07, 2020
Polyethylene glycol dialkyl ethers are well-established absorption fluids for scrubbing waste air and waste gas streams containing a variety of components, mostly solvents and acid gases.

Being mixtures of homologues, polyethylene glycol dialkyl ethers have average molecular masses. The higher molecular weight polyethylene glycol dialkyl ethers are thermally and chemically stable substances with low viscosities and low vapor pressures. They are excellent absorbents for AGR processes, mercaptane absorption and VOC abatement. In practice a large number of acid gas and waste gas purification plants are operated with Genosorb®. Gas streams ranging from 0.5 to > 500 000 Nm3/h are treated continuously.

Waste air purification, suitable for removal of e.g. solvents, e.g. chloronated hydrocarbons, ketones, esters.

VOC Abatement

The products Genosorb® 300 and Genosorb® 1843 were designed for scrubbing of VOCs such as alcohols, ketones, chlorinated and fluorinated hydrocarbons, aromatics, hydrocarbons etc.

They have proved successful in around 50 installations for VOC abatement around the world. Unlike incineration or adsorption, the Genosorb® process allows recycling of valuable organic compounds from waste gases. 

Genosorb® 300 is a polyglycol dimethyl ether and physically absorbs polar VOCs like alcohols, aldehydes etc. It is completely miscible with water. It contains a stabilizer and tolerates acidic components in the gas stream
