Process for the separation of air components, such as difficultly absorbable air impurities, out of air-gas mixtures.

摘要

An apparatus and process for separating and removing from air chemical impurities which are difficult to be absorbed, the apparatus for carrying out the process comprising a reaction tower (1) into which the air-gas-mixture is fed, aperture means (1b) in a wall of the tower, at least one filter means (2) positioned in the reaction tower, means for distributing (5) an absorbent medium onto the filter, collecting means (9) beneath the filter for the collection of the absorbent medium passing through the filter, and fan means (12) provided in the aperture for creating a flow of air through the reaction tower for the separation of substantially all of the impurities therefrom. As an absorbant medium caustic soda, sodium hypochlorite, water, hydrogen peroxide and mixtures thereof are particularly useful in the process.
