초록

The present invention reduces the sulfur and odor emissions from a paper-making Kraft process by recovering the sulfur in the non-combustible gases (NGCs) emitted by the Kraft process. In a first embodiment of the invention, the NGCs are flamelessly oxidized in a flameless thermal oxidizer to form a sulfur oxide-containing, gaseous products stream. The gaseous products stream is scrubbed with a scrubber solution stream to remove the sulfur components resulting in a scrubbed gas stream and spent scrubber solution stream having S.sub.2 O.sub.3 and SO.sub.4...

[ What is claimed is:] [1.] A method of removing sulfur from a process gas stream comprising the steps of:a. directing a lime mud stream into a calcinator;b. forming the lime mud stream into a packed bed in the calcinator;c. converting the lime mud in the calcinator into quick lime by heating the packed bed;d. preheating at least a portion of the packed bed to above 1400.degree. F.;e. subsequent to initiating the preheating step, directing the process gas stream through at least the portion of the packed bed, thereby establishing a reaction wave therein ...
