Abstract:
1. A rotating packed bed (RPB) arranged on a rotatable shaft, the RPB comprising: a first packed bed and second packed bed arranged adjacent to one another alongside the shaft, the first packed bed having an inner radius and an outer radius and the second packed bed having an inner radius and an outer radius, the RPB further comprising a gas inlet arranged at the rotating shaft or at the outer periphery of the first packed bed, respectively, and a first gas plenum extending from the shaft to the inner radius or from the casing to the outer radius, respectively, of the first packed bed, and a first liquid inlet arranged at the rotating shaft and liquid distribution means, the RPB further comprising a second gas plenum extending along the outer radius or long the inner radius, respectively, of the first packed bed and the outer radius or the inner radius, respectively, of the second packed bed and a third gas plenum extending from the inner radius or from the outer radius, respectively, of the second bed to the shaft and a second liquid inlet arranged at the rotating shaft and liquid distributor means, and wherein the liquid distributor means are arranged and configured to allow the liquid to flow through the first packed bed in co-current flow with the gas in a radially outward direction or arranged and configured to allow the liquid to flow through the first packed bed in a radially inward direction in counter-current flow with the gas, respectively, the liquid distributor means being also arranged and configured to allow the second liquid to pass through the second packed bed, in a radially outward direction in counter-current flow with the gas or arranged and configured to allow the second liquid to pass through the second packed bed in a radially outward direction in co-counter flow with the gas, respectively.
