Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of using an integrated lime hydrator in a plant, comprising: producing hydrated lime in at least one first stage housing having a bottom outlet and equipped with an adjustable control weir operable to cover any portion of the bottom outlet, a water supply, and a quicklime supply; and producing cured hydrated lime in-situ in a second stage housing equipped with a hydrated lime supply from the at least one first stage housing via the bottom outlet. 2. The method of claim 1 , further comprising producing moistened hydrated lime in a distribution device equipped with a water supply and a cured hydrated lime supply from the second stage housing; and reacting in a vertical reactor equipped with a flow of flue gas and the moistened hydrated lime supplied from the distribution device, the moistened hydrated lime with the flow of flue gas for flue gas acid gas reduction to produce cleaned flue gas. 3. The method of claim 1 , further comprising equipping the first stage housing with a cooling jacket operative for temperature control. 4. The method of claim 1 , further comprising operating the first stage housing at a temperature in the range of about 50 degrees Celsius to about 200 degrees Celsius. 5. The method of claim 1 , further comprising operating the second stage housing at a temperature in the range of about 50 degrees Celsius to about 200 degrees Celsius. 6. The method of claim 1 , further comprising controlling the water supply, the quicklime supply, the adjustable control weir, a temperature of the first stage housing, and a temperature of the second stage housing using a control device.
