Plant and method for producing liquefied natural gas and recovering carbon dioxide contained in natural gas and in a combustion exhaust gas

摘要

A plant for producing liquefied natural gas comprises a carbon dioxide recovery apparatus for natural gas absorbing and removing carbon dioxide from natural gas, a liquefying apparatus (40) having a steam turbine, for liquefying the natural gas from which carbon dioxide has been removed by the carbon dioxide recovery apparatus (10), a boiler equipment (50) for supplying steam to the steam turbine of the liquefying apparatus (40), and a carbon dioxide recovery apparatus (10) for combustion exhaust gas including an absorption tower for absorbing carbon dioxide from combustion exhaust gas exhausted from the boiler equipment (50) by absorbing liquid, and a regeneration tower for separating and recovering carbon dioxide from the absorbing liquid.
