A system for collecting carbon dioxide from a process gas, the system comprising: a gas source configured to be a source of the process gas; a condenser configured to receive the process gas, to condense water vapour in the process gas by cooling the process gas and to output a partially dry gas; a desiccant chamber configured to receive the partially dry gas from the condenser and to output a substantially dry gas, wherein the desiccant chamber comprises: a desiccant material configured to remove substantially all of the water vapour remaining in the partially dry gas, a first closed vessel defining a first hollow internal volume enclosing the desiccant material, and a first dielectric heater configured to direct electromagnetic radiation to water adsorbed onto the desiccant material to heat the adsorbed water and promote the release of the adsorbed water from the desiccant material; and, a contact chamber configured to receive the substantially dry gas from the desiccant chamber and output a substantially carbon dioxide-free dry gas, wherein the contact chamber comprises: an adsorbent material configured to adsorb substantially all the carbon dioxide from the substantially dry gas, a second closed vessel defining a second hollow internal volume for enclosing the adsorbent material, and a second dielectric heater configured to direct electromagnetic radiation to the carbon dioxide adsorbed onto the adsorbent material to heat the adsorbed carbon dioxide and promote the release of carbon dioxide molecules from the adsorbent material. a gas source configured to be a source of the process gas; a condenser configured to receive the process gas, to condense water vapour in the process gas by cooling the process gas and to output a partially dry gas; a desiccant chamber configured to receive the partially dry gas from the condenser and to output a substantially dry gas, wherein the desiccant chamber comprises: a desiccant material configured to remove substantially all of the water vapour remaining in the partially dry gas, a first closed vessel defining a first hollow internal volume enclosing the desiccant material, and a first dielectric heater configured to direct electromagnetic radiation to water adsorbed onto the desiccant material to heat the adsorbed water and promote the release of the adsorbed water from the desiccant material; and, a desiccant material configured to remove substantially all of the water vapour remaining in the partially dry gas, a first closed vessel defining a first hollow internal volume enclosing the desiccant material, and a first dielectric heater configured to direct electromagnetic radiation to water adsorbed onto the desiccant material to heat the adsorbed water and promote the release of the adsorbed water from the desiccant material; and, a contact chamber configured to receive the substantially dry gas from the desiccant chamber and output a substantially carbon dioxide-free dry gas, wherein the contact chamber comprises: an adsorbent material configured to adsorb substantially all the carbon dioxide from the substantially dry gas, a second closed vessel defining a second hollow internal volume for enclosing the adsorbent material, and a second dielectric heater configured to direct electromagnetic radiation to the carbon dioxide adsorbed onto the adsorbent material to heat the adsorbed carbon dioxide and promote the release of carbon dioxide molecules from the adsorbent material. an adsorbent material configured to adsorb substantially all the carbon dioxide from the substantially dry gas, a second closed vessel defining a second hollow internal volume for enclosing the adsorbent material, and a second dielectric heater configured to direct electromagnetic radiation to the carbon dioxide adsorbed onto the adsorbent material to heat the adsorbed carbon dioxide and promote the release of carbon dioxide molecules from the adsorbent material.
