Gas capture system

A regenerating reactor system for regenerating a sorbent of gas in a gas capture system, wherein the gas capture system is configured to capture said gas by recirculating the sorbent between a gas capturing system and the regenerating reactor system, wherein the regenerating reactor system comprises:

• a sorbent input for receiving a solid sorbent to be regenerated, wherein, when the regenerating system is in use, the sorbent is a sorbent of carbon dioxide gas;
• a combustor for generating heat by combusting a fuel with an oxidising agent in the presence of a catalyst;
• a moving bed reactor for regenerating the sorbent by using the heat generated by the combustor to indirectly heat the sorbent so that the sorbent releases carbon dioxide gas;
• a sorbent output for outputting the regenerated sorbent;
• and
• a gas output for outputting the released carbon dioxide gas;
• wherein, when the system is in use, the received sorbent comprises a metal carbonate and the regenerated sorbent comprises a metal oxide, and wherein the moving bed reactor comprises:
• a plurality of tubes that provide the generated heat to the moving bed reactor;
• the tubes are arranged in a plurality of horizontally aligned staggered layers;
• and
• the sorbent travels around the outside of the tubes as it moves from the sorbent input to the sorbent output.

A gas capture system for capturing a gas from a mixture of a plurality of gases, the system comprising:

• a gas input arranged to receive a mixture of a plurality of gases;
• a gas capturing system configured to use a sorbent to capture a gas within the received mixture of a plurality of gases;
• an output arranged to output gas that has had a gas captured from it by the gas capturing system;
• a regenerating reactor system, wherein the regenerating reactor system is configured to receive sorbent that has been used to capture a gas within the received mixture of a plurality of gases in the gas capturing system, regenerate the sorbent so that the sorbent releases the captured gas and output the regenerated sorbent;
• an output arranged to output the released gas during the regeneration of the sorbent by the regenerating reactor system;
• and
• a conduit that is arranged to provide a return path of the sorbent output from the regenerating reactor system to the input of the gas capturing system such that the sorbent is recirculated around the gas capture system;
• wherein the sorbent is a solid;
• wherein the regenerating reactor system comprises:
• a sorbent input for receiving a solid sorbent to be regenerated, wherein, when the regenerating system is in use, the sorbent is a sorbent of carbon dioxide gas;
• a combustor for generating heat by combusting a fuel with an oxidising agent in the presence of a catalyst;
• a moving bed reactor for regenerating the sorbent by using the heat generated by the combustor to indirectly heat the sorbent so that the sorbent releases carbon dioxide gas;
• a sorbent output for outputting the regenerated sorbent;
• and
• a gas output for outputting the released carbon dioxide gas, and wherein the moving bed reactor comprises:
• a plurality of tubes that provide the generated heat to the moving bed reactor;
• the tubes are arranged in a plurality of horizontally aligned staggered layers;
• and
• the sorbent travels around the outside of the tubes as it moves from the sorbent input to the sorbent output.
