PROCESS FOR THE RECOVERY OF CARBON DIOXIDE USING OXY-COMBUSTION GAS TURBINE COMBINED CYCLE POWER GENERATION FROM SYNTHESIS GAS OF THE IRON MAKING PROCESS OF FINEX OR COREX

摘要

PURPOSE: A process for recovering of carbon dioxide using an oxy-combustion gas turbine from synthesis gas of FINEX or COREX iron making process is provided to retrieve carbon dioxides by a carbon dioxide recovery part and to prevent the global warming. CONSTITUTION: The synthetic gas and pure oxygen are injected into a pure oxygen combustor(10). The combustion gas generated in the pure oxygen combustor is transferred to a gas turbine(20) in order to generate the energy. A part of generated exhaust gas is compressed and is circulated to a pure oxygen combustor. The rest exhaust gas is retrieved to a carbon dioxide recovery part(30) in order to collect the carbon dioxide. The synthetic gas is exhausted in FINEX and COREX iron making processes.
