Hcl Gas Absorber( Falling Flim Type )

We are offering The Falling Film Absorbers are typical Heat Exchangers with weir tube arrangement at the top - which is always vertically mounted.
In Falling Film Absorbers gas to beabsorbed enters atthe top of FFA and flows co currently with absorbent liquid coming from storage tank by pump.Heat of solution released as a result of the absorption process is removed by the cooling water flowing in the shell - side of the falling film unit. Thus noxious gas absorption is effected at lower temperatures enablinga higher absorption rate than adiabatic absorption towers.
The absorbed gas leaves at the bottom of FFA at a very low temperature for storage and disposal.
The un - absorbed gas and any inert gases also leave via vent at the bottom of FFA and enter the venturi scrubber or bottom of tail gas tower scrubber as is shown in the figure.
Falling film absorbers can be used for absorption of gases like HCl Cl2 So2 NOX HBr – where higher efficiencies of absorption are required.
