Hydrated lime having high surface area and small particle size is prepared by hydrating lime with an aqueous hydration solution of an organic solvent, and preferably washing the resulting hydrate with an aqueous solution of an organic solvent prior to drying. The high surface area hydrates of the invention are excellent sorbents for SO 2 removal from gas streams.
You can get Hydrated Lime at any hardware or home improvement store in the cement aisle. The Materials. When making your limewash, use a plastic bucket big enough that you can make enough mixture to cover your entire surface. It's very difficult to make two or three batches that will look and adhere the same.
Greer Lime Company owns our own on-site reserves of very pure, high calcium limestone. The same stone that enables us to produce high quality quicklime and hydrate is pulverized and classified into chemical grade products with agricultural, industrial, and mining applications.

Producing high surface hydrated lime. producing high surface hydrated lime As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any sizereduction requirements including quarry, aggregate, and different kinds of minerals.
The lower surface area lime is less reactive. If this type of lime were used to make a lime mortar it would have low strength and a much longer set time. The high surface area lime has many more surfaces open to reaction with atmospheric CO2 and is called a high-reactivity lime.
how to produce high surface area hydrated lime Standard Hydrated Lime is a refined hydrate that has a small median particle size, good flow properties, high surface area, and high total & available Ca(OH)2 Standard Hydrated Lime is used in flue gas treatment (for the control of SO 2 and S0.
The unique combination of high availability CaO, high reactivity and high particle surface area means that less of Graymont's lime will be required to "do the job", compared with other commercially produced lime products. Granulated lime. Granulated lime is a specially sized quicklime that meets exacting particle size specifications.

Hydrated lime for acid gas control There are currently over 30 coal-fired utilities mitigating SO 3 through DSI. A majority of these units utilize hydrated lime as their sorbent, specifically a high (>20 m2/g) BET surface area hydrated lime. Some units have a short (<1.5 sec) residence time between the injection point and an ESP
to form a lime slurry which is handled as a liquid.
