Abstract

One or more techniques and/or systems are disclosed for a process of reducing the usage of lime in a lime slurry, comprising the steps of: 1) forming a mixture comprising at least one polymeric dispersant comprising a straight chain polyacrylate homopolymer and a quantity of water; 2) introducing the mixture to a vessel prior to slaking for preparation of the lime slurry; and 3) slaking a quantity of lime and the mixture in the vessel to form the lime slurry, wherein the usage of lime in the lime slurry is reduced by about 25% to about 37%.

Claims (16)

1. A process of reducing the usage of lime in a lime slurry, comprising the steps of:

forming a mixture comprising at least one polymeric dispersant comprising a straight chain polyacrylate homopolymer and a quantity of water;

introducing the mixture to a vessel prior to slaking for preparation of the lime slurry, and

slaking a quantity of lime and the mixture in the vessel to form the lime slurry;

wherein the usage of lime in the lime slurry is reduced by about 25% to about 37% by weight; and

wherein the lime slurry is prepared under a continuous flow process.

2. The lime of claim 1 , wherein the lime is CaO.

3. The lime of claim 1 , wherein the lime is Ca(OH) 2 .

4. The polymeric dispersant of claim 1 , wherein the polymeric dispersant is about 0.3% to about 1.5% by weight of the lime slurry.

5. The process of claim 1 , wherein said at least one polymeric dispersant is heat-stable to about 101° C.

6. A process of reducing the usage of lime in a lime slurry, comprising the steps of:

forming a mixture comprising at least one polymeric dispersant and a quantity of water wherein at least one polymeric dispersant is a straight-chain polyacrylate homopolymer and wherein at least one polymeric dispersant is heat-stable;

adding the mixture comprising at least one polymeric dispersant and the quantity of water to a quantity of lime;

forming a lime slurry from the mixture comprising at least one polymeric dispersant, the quantity of water, and the quantity of lime,

wherein the usage of lime in the lime slurry is reduced by about 25% to about 37% by weight; and

wherein the lime slurry is prepared under a continuous flow process.
