摘要： A lime hydrator integrated into a flue gas desulfurization system or other industrial system is provided that provides an in-situ variable rate of cured hydrated lime production for a variable supply rate of the in-situ produced cured hydrated lime for use within a flue gas stream as a moistened hydrated lime for a reduction of acid gas present in a flue gas stream. Also provided is a method of using a lime hydrator integrated into a flue gas desulfurization system or other industrial system to provide in-situ a variable production rate of cured hydrated lime for a variable supply rate of the in-situ produced cured hydrated lime for use within a flue gas stream as a moistened hydrated lime for a reduction of acid gas present in a flue gas stream.

摘要： The present disclosure relates to a milk-of-lime preparation apparatus and preparation method having waste heat recovery line, that may recover waste heat generated during preparation of liquid milk-of-lime and deliver the recovered waste heat to water, so as to supply the water at an optimal temperature necessary for a hydration reaction, thereby increasing the reaction efficiency and reducing the preparation time of the milk-of-lime. Especially, the milk-of-lime preparation apparatus consists of a water tank that receives room temperature water from a water supply pipe and stores the received water inside the water tank; a raw material input pipe that transfers calcine lime powder from one end to the other end through pressure supply from a BCT vehicle that carries the calcine lime powder; a water input pipe of which one end is connected with the water tank, and that receives the water stored inside the water tank and transfers the received water to the other end; a milk-of-lime tank that receives the water from the other end of the water input pipe, that receives the calcine lime powder from the other end of the raw material input pipe, and that stirs the received calcine lime powder and the water by means of a stirrer installed inside the milk-of-lime tank, to prepare and store milk-of-lime; a discharge pipe that is installed at one side of the milk-of-lime tank to discharge the milk-of-lime stored inside the milk-of-lime tank; and a waste heat recovery line that circulates the water such that the water stored inside the water tank exchanges heat with the milk-of-lime stored inside the milk-of-lime tank and then is stored back inside the water tank.

摘要： A method of manufacture of high-solids hydroxide slurries from caustic calcined carbonate powder is described, whereby the properties of the slurry are its low resistance to shear thinning to facilitate transport, a high stability for transport and storage, ease of reconstitution after long periods of storage, and, as required, a high concentration of chemically reactive species at the particle surface. The method achieves these specifications by mixing caustic calcined carbonate or hydroxide powder with water in an insulated reactor vessel, and agitating the slurry sufficiently such that the hydration reaction causes the water to spontaneously boil, such that the remaining hydration proceeds spontaneously under the fixed conditions of boiling through the water loss. The mixing process is preferably carried out by a shear pump. A viscosity modifier, such as acetic acid, is used to thin the slurry to enable the mixing system to maintain uniform mixing. The reaction is terminated when the boiling has spontaneously ceased and the temperature has spontaneously dropped to a set point though the reactor heat losses, where the processing time is sufficiently long that the slurry meets the desired specifications.

摘要： A method of providing highly reactive hydrated lime and the resultant lime hydrate where an initial lime feed comprising calcium and impurities is first ground to a particle-size distribution with relatively course particles. Smaller particles are then removed from this ground lime and the smaller particles are hydrated and flash dried to form a hydrated lime, which is then milled to a significantly smaller particle size than that of the relatively course particles.
