Both hydrated lime (calcium hydroxide) and quicklime (calcium oxide) can be used with these systems, each requiring specific dry-to-slurry equipment. Facilities that use quicklime will require a lime slaker on-site to create a hydrated lime slurry prior to being fed to the stream of water, while facilities that use hydrated lime will only ...

Temperature range for effective removal is 300°F to 1500°F. Dry sorbent injection and new engineered sorbents have revolutionized dry removal of SO2, SO3, HCI and HF. Hydrated lime sorbents are easy to dispose of in landfills because of minimal leaching. High SO2 removal is possible without the cost and complexities of spray-drying or wet waste.

Hydrated lime, Calcium hydroxide (Ca (OH)2), also called slaked lime, is a white powder produced commercially when quicklime is mixed with water: CaO + H 2 O → Ca (OH) 2. Hydrated Lime has a variety of benefits when used for water and wastewater treatment, including acid neutralization, water softening, and impurity removal.

Injecting the hydrated lime after the air heater can lower SO 3 concentrations by 98%. Around 60% to 70% of the SO 3 can be removed when dry magnesium hydroxide is injected between the SCR and air heater at Mg:SO 3 molar ratios of 1:1 to 2:1, with removals greater than 80 percent also being achieved (Carpenter, 2012).

Hydrated lime, also known as calcium hydroxide {Ca (OH) 2 }, is a refined mineral product. Calcium oxide is stoichiometrically reacted with water in a controlled process to form a hydrated lime product that has the consistency of a fine white powder containing less than 1% residual moisture. Calcium Oxide + Water = Calcium Hydroxide + Heat.
