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%.

Abstract: 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.

Abstract: Novel hydrated-lime slurry compositions are disclosed, which include a heat-stable polymeric dispersant. The polymeric dispersant is capable to withstand temperatures in excess of 212° F. experienced by the slurry as a result of the hydrolysis of quicklime to produce hydrated lime, and accordingly can be added to the slurry composition prior to the addition of quicklime. Methods for making such slurry compositions are also disclosed.

Abstract: An improved water softening process is provided which also reduces anion content. A first stream of water is passed through an anion-exchange unit to remove undesirable anions and raise the pH. The first stream of water is then provided to reactor/clarifier water softening equipment, where it acts as a source of hydroxyl ions. Preferably a second stream of water which did not pass through an anion-exchange unit is also provided to the water softening equipment. The streams of water are combined and processed through the softening equipment, where hardness ions are precipitated out, yielding softened water with reduced anion content. The anion-exchange system utilized preferably has a counter-current continuous resin train and a counter-current continuous resin regeneration unit.

Abstract: Corrosion of ferrous metal surfaces in an aqueous system, such as a boiler system, is inhibited by adding a first component and a second component, the first component being preferably carbohydrazide, hydrazine, or a salt thereof, the second component being selected from the group consisting of certain hydroxylamine compounds or mixtures thereof, preferably N,N-diethylhydroxylamine. The weight ratio of the added first component to the added second component is between about 4:1 and about 1:4.

Abstract: A composition and method for inhibiting corrosion of ferrous metals comprising treatment with an admixture of a benzotriazole, a tolyltriazole, a substituted benzotriazole or a substituted tolyltriazole, with an acrylic or methacrylic acid ester polymer. The combination of ingredients provides unexpectedly superior corrosion protection when compared with either ingredient employed separately.
