A gas-liquid contacting apparatus and method are described, in which at least one rotor assembly including packing is arranged in a contacting chamber containing at least one stator assembly including at least one heat exchanger arranged to thermally modulate the gas-liquid contacting so that each stator assembly is operatively arranged with each stator assembly to provide gas-liquid contacting at temperatures effective for mass exchange between the gas and liquid. The rotor and stator assemblies may be of annular shape, or may be of disk shape in a stacked array of rotor assemblies alternating with stator assemblies. Such apparatus and method are usefully employed for CO2 capture from CO2-containing flue gases such as combustion effluents from power generation plants.
A method of contacting gas with liquid for mass transfer therebetween, said method comprising introducing the liquid into a contacting zone containing at least one rotating mass of packing and at least one stationary heat exchanger, wherein each rotating mass of packing is adjacent to at least one stationary heat exchanger, contacting the introduced liquid with gas in the contacting zone, discharging contacted liquid from the contacting zone, and discharging contacted gas from the contacting zone,
