Genosorb Absorption Liquids

Polyethylene glycol dialkyl ethers have proved very successful in practice for scrubbing waste air and waste gas streams containing a variety of organic substances - mostly solvents and acid gases.

Clariant has developed the Genosorb® range of absorption liquids as tailor made solution for many specific waste gas problems. Genosorb absorption liquids have a low vapor pressure and low viscosity

A waste gas stream containing VOCs and / or acid gases is passed through a packed tower. The removal of VOCs is accomplished with a direct contact between the upward gas and the downward Genosorb absorption liquid. This rich Genosorb solution is then passed downward through a packed stripping tower. The VOCs are removed from Genosorb by stripping with steam or air, typically at temperatures between 70°C and 130°C. The resulting lean Genosorb solution is then passed back to the absorber column.
