APPARATUS FOR CARBON DIOXIDE ENRICHMENT

摘要

A flue gas treatment apparatus has a flue gas inlet, a treated gas outlet downstream of the flue gas inlet, and a gas flow path therebetween. The flue gas treatment apparatus comprises a particulate removal device. A first heater is downstream of the particulate removal device. The first heater heats the flue gas to a first treatment temperature. A first catalytic converter is downstream of the first heater for eliminating at least some CO and SO2 from the flue gas. A second heater is downstream of the first catalytic converter for heating the flue gas to a second treatment temperature. A second catalytic converter is downstream of the second heater for eliminating at least some NOx from the flue gas. At least a first fan forces the flue gas from the flue gas inlet to the treated gas outlet.

1. An apparatus for carbon dioxide enrichment comprising:
a) a combustion furnace for generating a carbon dioxide rich flue gas, the combustion furnace having a flue gas outlet; b) a flue gas treatment apparatus having a flue gas inlet in communication with the flue gas outlet, a treated gas outlet downstream of the flue gas inlet, and a gas flow path therebetween, the flue gas treatment apparatus comprising:
i) a particulate removal device in the gas flow path for eliminating at least some particulate matter from the flue gas;ii) a first heater in the gas flow path downstream of the particulate removal device, the first heater for heating the flue gas to a first treatment temperature;iii) a first catalytic converter in the gas flow path downstream of the first heater for eliminating at least some carbon monoxide and sulfur dioxide from the flue gas;iv) a second heater in the gas flow path downstream of the first catalytic converter for heating the flue gas to a second treatment temperature;v) a second catalytic converter in the gas flow path downstream of the second heater for eliminating at least some NOx from the flue gas; andvi) at least a first fan for forcing the flue gas from the flue gas inlet to the treated gas outlet.
