  • Patent number: 9919267
    Abstract: A gas-liquid contactor includes: a plurality of packing material sections through which exhaust gas passes; and a plurality of liquid distributors provided upon each of the plurality of packing material sections, dispersing a CO2 absorption liquid caused to come in contact with the exhaust gas, and supplying the CO2 absorption liquid to the plurality of packing material sections. The plurality of packing material sections include a first packing material layer and a second packing material layer that have provided therein flow paths (111a, 112a) for the CO2 absorption fluid that each extend in prescribed directions (D2, D3). The first packing material layer and the second packing material layer are characterized by being laminated such that the directions (D2, D3) of extension of the flow paths (111a, 112a) in the flow direction (D1) for the exhaust gas are different from each other.
    Type: Grant

  • Patent number: 9568193
    Abstract: An air pollution control system includes: a desulfurization device which removes sulfur oxides in a flue gas generated from a boiler; a cooler which is provided at the downstream side of the desulfurization device, decreases a flue gas temperature and enlarges a particle diameter of SO3 mist contained in the flue gas through cooling or heating the flue gas by a temperature adjustment means for adjusting a gas dew point temperature of the flue gas; and a CO2 recovery device which includes a CO2 absorber bringing CO2 in the flue gas into contact with the CO2 absorbent so as to remove CO2 therefrom and a regenerator recovering CO2 by dissociating CO2 from the CO2 absorbent and regenerating the CO2 absorbent, wherein the flue gas is cooled by a cooling unit so as to enlarge the SO3 mist in the flue gas.

  • Patent number: 9227154
    Abstract: A gas-liquid contactor includes a plurality of spray nozzles provided in a CO2 absorber, for spraying a CO2 absorbent downward into the CO2 absorber in which flue gas drifts upward and passes so as to bring flue gas drifting upward and the CO2 absorbent into contact with each other. The spray nozzle includes a wall-surface dedicated nozzle provided along a wall surface in the CO2 absorber and a liquid dispersion nozzle provided inside of the wall-surface dedicated nozzle in the CO2 absorber.
