1. A gas capture system comprising:
a rotating packed bed, RPB, system; and
a gas supply arranged to provide a gas flow into the RPB system, wherein the gas flow is a gas mixture that comprises carbon dioxide gas;
wherein the RPB system comprises a RPB arranged to provide mass transfer from the gas flow to a sorbent so as to reinduce the concentration of carbon dioxide in the gas flow, the RPB comprising:
a central chamber arranged such that, in use, the central chamber receives 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 from the gas to 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;
wherein the RPB further comprises:
first packing material; and
second packing material that is configured to provide the region for mass transfer between the gas and the sorbent;
wherein, in use:
the first packing material is arranged to receive sorbent from the central chamber;
the second packing material is arranged to receive sorbent from the first packing material; and
the sorbent flow resistance of the second packing material is less than the sorbent flow resistance of the first packing material.
