PROCESS FOR LIME SLURRY PRODUCTION
A process for controlling scaling on and within lime slaking and handling equipment such as SDA atomizers and reducing lime usage by forming a mixture with at least one polymeric dispersant and a quantity of water and introducing the mixture to a vessel for preparation of a lime slurry.
1 . A process of making an alkaline-neutralization agent, comprising the steps of:
forming a mixture comprising at least one polymeric dispersant and a quantity of water; and
introducing said mixture to a vessel for preparation of a slurry.
2 . The process of claim 1 , wherein said alkaline-neutralization agent comprises a lime slurry.
3 . The process of claim 1 , wherein the step of forming said mixture comprising at least one polymeric dispersant and a quantity of water occurs prior to the step of introducing said mixture to said vessel.
4 . The process of claim 1 , wherein the step of forming said mixture comprising at least one polymeric dispersant and a quantity of water occurs simultaneously with the step of introducing said mixture to said vessel.
5 . The process claim 1 , wherein the step of forming said mixture further comprises the step of adding said quantity of water to said at least one polymeric dispersant.
6 . The process of claim 1 , wherein the step of forming said mixture further comprises the step of adding said at least one polymeric dispersant to said quantity of water.
7 . The process of claim 1 , wherein said at least one polymeric dispersant is a straight-chain polyacrylate homopolymer.
8 . The process of claim 1 , wherein said at least one polymeric dispersant is heat-stable.
9 . The process of claim 1 , wherein said slurry is prepared under a batch process.
10 . The process of claim 1 , wherein said slurry is prepared under a continuous flow process.
11 . The process of claim 1 , further comprising the step of reducing scaling.
12 . The process of claim 1 , further comprising the step of reducing alkaline chemical usage.
13 . The process of claim 1 , further comprising the step of reducing waste ash.
14 . The process of claim 1 , further comprising the step of reducing mercury gas emissions.
15 . A process of making a lime slurry, comprising the steps of:
forming a mixture comprising at least one polymeric dispersant and a quantity of water wherein said at least one polymeric dispersant is a straight-chain polyacrylate homopolymer and wherein said at least one polymeric dispersant is heat-stable;
forming a mixture comprising at least one polymeric dispersant and a quantity of water wherein said at least one polymeric dispersant is added to said quantity of water; and
introducing said mixture to a vessel for preparation of a slurry wherein said process reduces scaling, reduces alkaline chemical usage, and reduces waste ash, and reduces mercury gas emissions.
16 . A process of making a lime slurry, comprising the steps of:
forming a mixture comprising at least one polymeric dispersant and a quantity of water wherein said at least one polymeric dispersant is a straight-chain polyacrylate homopolymer and wherein said at least one polymeric dispersant is heat-stable; and
forming a mixture comprising at least one polymeric dispersant and a quantity of water wherein said at least one polymeric dispersant is added to said quantity of water.
17 . The process of claim 16 , further comprising the step of reducing scaling.
18 . The process of claim 16 , further comprising the step of reducing alkaline chemical usage.
19 . The process of claim 16 , further comprising the step of reducing waste ash.
20 . The process of claim 16 , further comprising the step of reducing mercury gas emissions.
