Abstract

This paper describes modifications to improve the feasibility of a pre-combustion CCS concept for a gas turbine combined cycle. A natural gas-fired greenfield combined heat and power (CHP) plant equipped with pre-combustion capture was used as a base case, for which various improvement options were identified, assessed and selected. The base case was modified using the selected improvement options, after which the investment costs were re-evaluated. The results showed that the investment cost can be reduced with 8 % by excluding the pre-reformer and the low temperature water-gas-shift reactor from the reforming process. The exclusion of the pre-reformer did not affect the performance of the plant, but the exclusion of the low temperature water-gas-shift reactor led to higher CO₂ emissions.
