An innovative method of activating lime waste. Waste – sorbent - product

Abstract

The paper presents the production technology of sorbents for flue gas desulphurization with the wet limestone method, produced on the basis of limestone waste. The waste was subjected to comprehensive physicochemical tests and the following were studied: size distribution, chemical composition, morphology and reactivity. The analysed waste was subjected to electromagnetic activation to improve the sorption properties lost in the original process. The effect of the activation process was determined by comparing physicochemical properties of the waste before and after its activation. Based on the experience gained, an industrial installation was designed and manufactured industrial.
