Abstract
Apparatus and methods for reducing CO,content of an air stream are described. A method of reducing CO,content of an air stream in accordance with one embodiment of the present invention includes the steps of first injecting hydrated lime into an air stream containing CO,. The hydrated lime reacts with the CO,in the air stream to form calcium carbonate, CaCO,. The air stream is then directed into a lime storage container having a dust collector. As air is drawn through the dust collector, hydrated lime and CaCO,are collected on the filter bags. The air drawn through the dust collector has a reduced CO,content as compared to the air prior to being injected with hydrated lime. The reduced CO,content air stream exhausted from the dust collector can then be directed to the different parts of the hydrated lime manufacturing process, such as the milling process, conveying and storing the hydrated lime.
