Method and apparatus for the removal of objectionable volatile compounds from hot gases

摘要

Method and apparatus for removing objectionable volatile compounds from hot gases such as those produced during the manufacture of cement wherein the hot gases containing such volatiles are cooled to the extent that at least a portion of such compounds are condensed into a powdery, solid form. These very fine particles are collected along with cement particles and consolidated as by means of roll presses into coherent solid shapes of larger area which can be used, for example, as fertilizer pellets.
