Patent ID: 7531144

Claim:
A system for the reduction of CO 2 levels in an exhaust gas resulting from gas combustion in a combustion unit, said system comprising: one or more heat exchangers arranged for the transferral of heat energy from salt water and combustion air to liquefied natural gas to form cooled salt water and to evaporate said liquefied natural gas to fuel gas; means for mixing said fuel gas with said combustion air for gas combustion which generates exhaust gas containing CO 2 ; and a process unit to which, subsequent to the gas combustion, the exhaust gas is furnished, and which is constructed and arranged to mix NH 4 OH with said cooled salt water to form cooled NH 4 OH comprising salt water; wherein said process unit is configured to cause said cooled NH 4 OH comprising salt water to contact said exhaust gas, such that at least a portion of the CO 2 contained in said exhaust gas reacts with the cooled NH 4 OH comprising salt water such that the CO 2 level is reduced in said exhaust gas which is output from said process unit, and further configured to cause formation of a mix of process unit products NaHCO 3 , NH 4 Cl and fresh water, said process unit comprising a first outlet for said exhaust gas with said reduced CO 2 level and a second outlet for said mix of process unit products.
