Abstract
Absorption process comprising supplying impure sulfur-containing exhaust gases into a gas supply which conduit defines a vertically-upward path followed by a vertically-downward path. The end of the vertically-downward path leading to a branch has an outlet opening communicating with a water-cooled bath, through which bath containing sulfuric acid a conduit for the continued passage of the exhaust gases extends in an end-to-end manner, the conduit at its inboard end defining an inlet opening disposed above the level of the sulfuric acid in the bath and the conduit at its outboard end turning upon itself to define an outlet opening disposed below the level of the sulfuric acid in the bath while the outboard end of the bath communicates with a gas outlet conduit venting the cleansed air to atmosphere by a vacuum pump.
Claims1
An absorption process for purifying sulfur-containing exhaust gases emanating from a smoke-generating facility comprising the steps:
- conducting the exhaust gases from the facility through a connecting gas inlet conduit to a water-cooled sulfuric acid bath communicating with the conduit,
- directing the gases through the length of the bath via a bath conduit having an upstream entrance terminal disposed in the gas supply conduit and above the acid level in the bath and having a downstream discharge terminal reversed upon itself interiorly of the bath for the direct charge of the gases into the acid below the acid level in the bath, and
- drawing by means of a vacuum pump the cleansed exhaust gases outwardly of the acid in the bath through a connecting gas outlet conduit for the venting of the cleansed gases therefrom to atmosphere.
