SULF-X PROCESS<br />
INIS: 2000-04-12; ETDE: 1985-02-22<br />
The sulf-x process is a wet absorption process<br />
that utilizes a slurry of reg<strong>en</strong>erated ferrous<br />
sulfide solids to achieve removal of 90 to 99%<br />
of sulfur dioxide <strong>fr</strong>om boiler flue gases by wet<br />
scrubbing. It is technically feasible for use<br />
with all fossil-fuel types.<br />
