Abstract: Disclosed herein is a rotating packed bed, RPB, for mass transfer between a sorbent and a gas, the RPB comprising: a central chamber arranged to receive a flow of a sorbent that is a liquid; and a flow path for the sorbent between the central chamber and a region for mass transfer between a gas and the sorbent; wherein, in use, the flow of sorbent through the region for mass transfer is substantially in cross-flow with the flow of gas through the region for mass transfer. Advantageously, mass transfer between a liquid sorbent and a gas is improved.

Abstract: Disclosed herein is a gas capture system comprising: a gas inlet arranged to receive a gas flow into the system; a gas outlet arranged to provide a gas flow out of the system; a gas capture region for mass transfer between a gas and a sorbent of the gas; and a sorbent regeneration region for regenerating the sorbent by heating the sorbent so that the sorbent releases a gas; wherein: the gas capture region is arranged to receive sorbent from the sorbent regeneration region; the sorbent regeneration region is arranged to receive sorbent for regeneration from the gas capture region; the sorbent is a solid sorbent of carbon dioxide gas; and the gas capture region comprises: a sorbent inlet arranged to receive an input of sorbent into the gas capture region; a sorbent outlet arranged to provide an output of sorbent from the gas capture region; one or more mass transfer regions arranged between the sorbent inlet and the sorbent outlet such that, in use, the sorbent is retained within the one or more mass transfer r

Abstract: The present invention relates to a system for desorption of acid gas (1) from an acid gas rich absorption liquid having a steam part (3) and a process part (4). The steam part (3) and the process part (4) are separated to prevent intermixing of fluids in the steam part with fluids in the process part. The system (1) comprises a desorption cylinder (9) which is adapted to rotate about a longitudinal axis of rotation A of the desorption cylinder (9), and a stationary support stand (19) for supporting the desorption cylinder (9), and means for rotating (18) the desorption cylinder. The steam part (3) and the process part (4) are integrated in the desorption cylinder (9) and steam is supplied to the steam part (3) and acid gas rich absorption liquid (2) is supplied to the process part (4).
