TURBINE FACILITY CO-PRODUCING ALKALINE CARBONATE AND POWER GENERATING FACILITY CO-PRODUCING ALKALINE CARBONATE

摘要

PROBLEM TO BE SOLVED: To provide a turbine facility co-producing alkaline carbonate capable of separating and collecting CO2, and applying CO2in the system for production of Na2CO3to thereby effectively use CO2.

SOLUTION: The turbine facility co-producing alkaline carbonate is equipped with a supply system compressing a portion of CO2in exhaust gas in a gas turbine 4 and supplying it to a combustor 3, a CO2collecting system for collecting CO2from the exhaust gas in the gas turbine 4, and a sodium carbonate collecting means 8 for obtaining Na2CO3by reaction of CO2inside the CO2collecting system with NaOH. Na2CO3is obtained by reacting CO2from a portion of the exhaust gas in the gas turbine 4 (in the system) with NaOH.
