PROCESS FOR THE REMOVAL OF SULFUROUS GASES FROM THE EMISSIONS OF CHEMICAL PROCESSES ABSTRACT OF THE DISCLOSURE A process for removing sulfurous by-product materials from high temperature reaction products of chemical processes consisting essentially in: (1) passing a simple or complex metal oxide in the form of a coarsely divided powder entrained in a conveying gas through a high energy transfer zone whereby said powder is heated to a degree sufficient to vaporize said powder and said powder is substantially vaporized to form a hot effluent stream of metal oxide vapor, (2) injecting said hot effluent stream of metal oxide vapor into a gaseous reaction product, including sulfurous by-product materials, from an elevated temperature chemical process, (3) allowing said metal oxide vapor to condense to solid particles with reaction with said sulfurous by-product materials to fix the sulfur content thereof in the form of solid particles, and (4) separating said solid particles containing substan- tially all of the sulfur content of said sulfurous by-product materials from said gaseous reaction product. -1-
