Electrochemical cell, method and apparatus for capturing carbon dioxide from flue gas and decomposing nitrosamine compounds

An apparatus for capturing CO2 from flue gas, comprising:

• an absorber including a flue gas inlet, a flue gas outlet, a CO2-lean amine absorbent inlet and a CO2-rich amine absorbent outlet;
• a stripper including a CO2-rich amine absorbent inlet, a CO2-lean amine absorbent outlet and a captured CO2 outlet;
• a heat exchanger adapted to receive (a) CO2-lean amine absorbent from said stripper being delivered to said CO2-lean absorbent inlet and (b) CO2-rich amine absorbent from said absorber being delivered to said CO2-rich amine absorbent inlet;
• an amine absorbent circulating through said absorber, said stripper and said heat exchanger;
• a water washing unit downstream from said flue gas outlet;
• and
• an electrochemical cell connected to said water washing unit and adapted to adsorb and decompose nitrosamine compounds present in liquid separated by said water washing unit.
