Abstract
A device for separating and compressing carbon dioxide from a carbonate salt comprises an anion membrane and a cation membrane. The anion and cation membranes define a fluid feed compartment. The anion membrane has an anode disposed on it. The cation membrane has a cathode disposed on it. An enclosed carbon dioxide collection compartment, in which carbon dioxide pressure can be regulated, is located adjacent to the anode. The device also has an enclosed scrubbing fluid collection compartment adjacent to the cathode and means for inducing an electrical potential across the anode and cathode. The device is capable of supplying carbon dioxide at high pressures when a carbonate salt is fed to the fluid feed compartment and an electrical potential is induced across the anode and cathode.
