发明名称 Process for desulfurizing a sulfur-dioxide containing gas
摘要 <p>A desulfurization process using magnesium sulfites in a clear solution have the discharge from a wet scrubbing unit (1) passed to a reaction tank (11). A silica-containing solid particulate material, such as sand, added to the reaction tank and lime is added to precipitat calcium sulfite solids onto the particulate material. The resulting solids, a calcium sulfite coated, silica containing solid particulate material, are readil dewatered and may be used in a cement manufacturin process. &lt;IMAGE&gt;</p>
