Abstract
The invention relates to a method for reduction of HCl emission from a cement plant based on a treatment of a preheater () and/or bypass gas stream, characterized in that a cement raw meal, as a HCl absorber, is dispersed in the gas stream(s) from which HCl is to be removed; the cement raw meal is introduced from a raw mill () and/or a silo () into a pipe with a up going gas flow; the pipe being arranged in fluid communication at a point after a gas conditioning tower () and/or before a particle filter unit () and/or in a by-pass line before particle filter ().
