Dry Sorbent Injection | Carmeuse

Dry Sorbent Injection (DSI) consists of the direct injection of an alkaline material, typically hydrated lime (Ca(OH)2), into the flue gas before the dedusting unit. The neutralization of acid gas starts at the injection point and continues down to the filter. The location of the injection points is thus very critical as the flue gas characteristics at this point will greatly influence the ...

Macropore-Stabilized Limestone Sorbents Prepared by the ...

A novel cost-effective method was applied to modified calcium-based sorbents for cyclic high-temperature CO2 capture. The sorbents were derived from cheap limestone and sea salt, and the main processes of the preparation involved two simple steps: hydration of CaO and impregnation with sea salt in CaO. Results indicated that the simultaneous hydration–impregnation (SHI) method contributed to ...

Limestone: Rock Uses, Formation, Composition, Pictures

Ideally, a sorbent reactivation process ought to bring the level of activity of the unreacted portion of the sorbent back to that of the original unreacted limestone. In practice, for "good" limestone sorbents in CFBC boilers 90% sulphur capture can be achieved with a Ca:S molar ratio of ∼2–2.5 (i.e., ∼35–45% utilization of the CaO).
