Abstract

The waste gas flows through a casing so that it must pass through grids sprayed with an appropriate washing liq. via nozzles fitted on pipes into which the liq. is pumped; the liq. forms a film on the grids. After passing through the grids, the gas flows through polypropylene grids employed to remove fine drops of the washing liq. picked up by the gas. Casing pref. contains >=2 sets of grids so the gas is washed in >=2 stages. Appts. is used esp. to remove HCl from gas leaving a pickling plant, where the HCl leaving the first washing and filtration stage is returned to the pickling plant and the residual air can be released to the environment. Process prevents pollution of the environment by pickling fumes, while also reclaiming chemicals, esp. HCl, for re-use.
