Patent number: 7531144Abstract: This invention relates to a method for desalination of seawater (5, 30) and separation of CO2 from exhaust (77) from a gas turbine (7). LNG (4) is fed into a heat exchanger (6) in which it receives heat from seawater (5) and heat from steam (27) from an exhaust boiler, and heat from combustion air (3) via a line to an air inlet (33) of said gas turbine (7), for evaporating LNG (4) to gas which is fed to a gas export module (10) and to a fuel gas skid (8) for supplying said gas turbine (7) with fuel. Thus said combustion air (3, 28) at the air inlet to said gas turbine (7) obtains a lowered temperature and increases an efficiency of said gas turbine (7). Said CO2-rich exhaust gas (77) from said gas turbine (7) is fed into a process unit (17) having an inlet (35a) with a fan (35b) and an outlet for CO2-reduced exhaust (13). Said cooled seawater from said heat exchanger (6) is fed into said process unit (17) via a coaxial feed pipe (67) for seawater and NH4OH arranged in said process unit (17).Type: GrantFiled: November 8, 2007Date of Patent: May 12, 2009Assignee: Sargas ASInventor: Knut Erik Borseth
