Abstract: The present invention relates to a method and system for removing an impurity from a feed gas stream. Various embodiments include, for example, using a rotating packed bed, a pressure reducing device such as a turbine and/or control valve, a regenerator, and novel internal seal designs and liquid distributors. Advantageously, at least a portion of any energy produced is recycled for use in the process or elsewhere.

Abstract: Provided is a method, liquid distributor and reactor for contacting a gas with a liquid in a rotating packed bed. The method comprises providing a rotating packed bed comprising two sets of rotatable packing rings disposed within a chamber and defining an interior region. The rotating packed bed also comprises at least one liquid distributor with an inlet for accepting a liquid, the inlet in communication with an exit port for infusing the liquid into the interior region. The liquid distributor also comprises at least one gas outlet for accepting gas which has passed through the packed bed and for removing the gas from the interior region. The two sets of rotatable packing rings are caused to rotate. Liquid is infused into the interior region by way of the liquid inlet, and gas is injected through at least one gas inlet into the interior region, with the liquid and gas passing through each of the packing rings in countercurrent flow.
