Carbon dioxide treatment system

Abstract

This invention provides a carbon dioxide treatment system capable of supplying a predetermined solution suitable for the recipient. [Solution] The processing system comprises an electrolytic unit that reduces carbon dioxide to produce carbon compounds, a generating unit that generates a gas containing carbon dioxide from a predetermined solution in which carbon dioxide is dissolved, and a storage unit that stores the predetermined solution. The electrolytic unit comprises a first cathode, a first anode, an anion exchange membrane disposed between the first cathode and the first anode, and a first anode chamber that supplies the predetermined solution to the first anode. The predetermined solution stored in the storage unit is circulated between the first anode chamber and the storage unit before being supplied to the generating unit.

Claims
