Abstract

The invention relates to the method for separating gaseous polluants, such as sulphur dioxide, from hot process gases, such as flue gases, where the hot gases are passing through a contact reactor, in which is introduced the moistened absorbent material, which is reactive with gaseous polluants, to convert the gaseous polluants into separable dust, the process gases are then passing through a dust separator. The major part of the dust separated in the dust separator is passing to a mixer, in which it is mixed and moistened with a fresh absorbent, whereupon it is recirculated as absorbent material by being introduced. Into the process gases burnt lime is added as fresh absorbent. The dust is kept so long in the mixer and recirculated so many times that the total residence time of the burnt lime in the mixer in moistened state is sufficiently long for the burnt lime to react substantially completely with water supplied to the mixer and form slaked lime.The technical result of the invention consists in reducing the price of method by means of application of the slaked lime instead of the burnt lime.
