Water is added to slake the lime at the satellite plant next to the paper mill The resulting milk of lime a suspension of Ca OH 2 is then exposed to bubbles of CO 2 gas Often it is possible to collect a stream of CO 2 gas from a kraft recovery operation or power generating operation at the mill site
by the handling and storage of intermediate and final materials production is generally lower in lime manufacturing than in cement manufacturing Because limestone burning usual ly takes place at lower temperatures NO X emissions from this source are lower and can be controlled using low NO X burners Sulfur Dioxides Sulfur dioxide SO 2 emissions in cement manufacturing are primarily
Lime slaking is the process of converting quicklime to hydrated lime CaO H20 > Ca OH 2 by mixing with water Lime slaking is an exothermic process which generates heat and creates steam Slaked or hydrated lime is often used in mining and process industries for
