ABSTRACT:
A method of processing waste gases containing sulphurous-acid anhydride comprises contacting said waste gases with an aqueous solution of sulphuric acid in the presence of oxygen or air and a catalyst comprising an inorganic manganese salt, such as manganese sulphate, perchlorate, chloride, nitrate or phosphate used in an amount of 0.0003-0.03 wt.% based on manganese ion to obtain an aqueous solution of sulphuric acid containing sulphurous-acid anhydride. This solution is subjected to the action of an agent for initiating the oxidation of sulphurous-acid anhydride comprising ionizing radiation to obtain an aqueous solution of sulphuric acid free from sulphurous-acid anhydride. A part of the sulphuric acid is derived from the cycle in the form of the resulting aqueous solution in an amount equivalent to the amount of the oxidized sulphurous-acid anhydride, and the remaining part of the sulphuric acid is fed for contacting with the waste gases.
The method permits the processing of waste gases containing up to 0.4 vol.% of sulphurous-acid anhydride using a simple production technique with a high degree of purification, as well as obtaining commercial sulphuric acid with a concentration up to 50%.
