Method for treatment of calcium containing solids, involves exposing solid for treatment of as mixture, which contains reactive gas or reactive gas mixture or reactive aerosol compared with solid

摘要

The method involves exposing the solid for treatment of a gas mixture, which contains a reactive gas or a reactive gas mixture, contains a hydrochloric acid, or nitrogen dioxide or hydrogen fluoride contain, or a reactive aerosol compared with the solid, by forming a solid reaction product. The reaction product is thermo-dynamically less stable than the solid, which is formed with the separation of the waste gas part by the calcium containing solid. The calcium containing solid has calcium hydroxide or calcium oxide, or calcium carbonate or mixture.
