GAB-Neumann - Annular Groove Isothermal Graphite Absorbers - Brochure

Annular groove isothermal graphite absorbers are graphite heat exchangers adapted to the absorption of ultra-corrosive gases such as hydrochloric, bromhydric or hydrofluoric acids. The equipment works as a number of water cooled-wall tiny columns in parallel. Each tiny column is provided with a liquid distribution system on top to ensure the uniform distribution of both liquid and gas and also form a thin liquid film at the surface of the column.
