摘要:
Disclosed is a dry CO 2 capturing device using multi sorbents so as to maintain the sorption rate for exhaust gas containing CO 2 . The dry carbon dioxide (CO 2 ) capturing device comprises at least two dry carbon dioxide (CO 2 ) capturing parts comprising: a first and second recovery reactors 104 and 105 to recover CO 2 by contacting a solid sorbent with exhaust gas; a first and second recovery cyclones 106 and 122 connected to the recovery reactors; a first and second regenerators 110 and 126 connected to the recovery cyclones; and a first and second pre-treatment reactors 116 and 132 connected to the regenerators through sorbent supply lines. The first and second dry carbon dioxide (CO 2 ) capturing parts are connected to each other so as to feed an isolated gas, which is separated with the solid sorbent in the first recovery cyclone 106 of the first dry CO 2 capturing part, to the second dry CO 2 capturing part through the exhaust gas supply line, and different solid sorbents are used in the first and second CO 2 capturing parts.

摘要:
Disclosed is a dry CO 2 capturing device with improved energy efficiency, which utilizes a difference in temperature between a regeneration operation of isolating CO 2 from an sorbent containing CO 2 absorbed therein and a pre-treatment operation of allowing H 2 O to be adsorbed to CO 2 . The dry carbon dioxide (CO 2 ) capturing device, includes a recovery reactor for recovering CO 2 , a recovery cyclone for discharging a gas while separating the CO 2 -captured solid sorbent only, a regenerator for receiving the CO 2 -captured solid sorbent and separating CO 2 captured in the solid sorbent, and a pre-treatment reactor for cooling the solid sorbent free from CO 2 , wherein a first heat exchanger is provided between the recovery cyclone and the regenerator to pass the CO 2 -captured solid sorbent therethrough, and a second heat exchanger is provided between the pre-treatment reactor and the regenerator to pass the solid sorbent free from CO 2 therethrough. The first and second heat exchanger include a first and second heat exchange jacket mounted thereon which are connected to each other in a closed loop state.

摘要:
Disclosed are an exhaust gas treating apparatus and a treating method for a carbon dioxide capture process, in which harmful substances remaining in the exhaust gas discharged from the conventional flue-gas desulfurization process are additionally removed for efficient performance of the carbon dioxide capture process. According to the exhaust gas treating apparatus for a carbon dioxide capture process, it has the effects of minimizing the installation space of desulfurization equipment and reducing the process cost. In addition, by keeping the contaminants contained in the gas introduced in the carbon dioxide capture equipment below a proper level, absorption performance can be improved as degradation of the absorbent used in the carbon dioxide capture process is prevented. After all, it has an advantage of preventing the pollution by the exhaust gas discharged into the atmosphere.
摘要:
Disclosed is a system for purifying high-temperature high-pressure contaminated gas which includes a dehalogenation process for removing halogen compounds from a raw gas by recycling a dry carbon dioxide sorbent that has been exhausted by repeated removing of carbon dioxide. The system 10 includes a desulfurization apparatus 200 which removes sulfur compounds from a raw gas; and a dehalogenation apparatus 100 which is disposed at a front or rear of the desulfurization apparatus 200 to remove halogen compounds. The dehalogenation apparatus 100 includes dehalogenation reactors 104 and 108 into which a dry carbon dioxide sorbent is introduced, and dehalogenation cyclones 106 and 110 which separate the dry carbon dioxide sorbents from a mixture of a dehalogenation gas and the dry carbon dioxide sorbents discharged from the dehalogenation reactor 100 and discharges only the dehalogenation gas.
