International Classification:
B01D 53/14, B03C 3/16, G01J 3/44
US Classification:

Abstract:
A method and apparatus for removing carbon dioxide and other pollutants from a gas stream having components that work synergistically. The invention includes an ammonia based scrubbing solution for SO2 scrubbing; an SO2 absorption section () to create contact between the flue gas and the ammonia based scrubbing solution to remove SO2 from the flue gas; a wet electrostatic precipitator to remove aerosols and fine particulate matter from the flue gas; a regenerable carbonate scrubbing solution for CO2 scrubbing, a CO2 absorption section () for removal of CO2 adapted to create contact between the flue gas and the scrubbing solution and which operates at a temperature between 32 and 66 degrees C. and including mass transfer apparatus and liquid distribution apparatus to provide the gas and liquid contact; an ammonia absorption section () to capture ammonia vapor which creates contact between at least some of the liquid leaving the SO2 absorption section and the gas leaving the CO2 absorption section and return ammonia rich liquid leaving the CO2 absorption section to the SO2 absorption section for use in SO2 capture; a regeneration tower () to release CO2 from the scrubbing solution, the regeneration tower comprising: packing for mass transfer; apparatus for allowing the spent scrubbing solution to be introduced at elevated temperature; and apparatus for introducing heat to the regenerator tower, a controller for controlling the absorption and regeneration system parameters selected from the group consisting of gas inlet temperature, reagent feed rates, regeneration temperature and pressure, and system differential pressure; and a heat recovery device to recover energy during the heating and cooling of the absorption and regeneration column liquids.

International Classification:
B01D 53/14
US Classification:
95159, 252184
Abstract:
Absorption media for separating acidic gases such as C02 from a gas stream are disclosed. In some embodiments, the Absorption media include a solution of water, at least piperazine or a derivative of piperazine, and at least one alkali ion. The at least one alkali ion may be potassium. Methods and apparatus for separating acidic gases from a gas stream using such absorption media are also disclosed.
