Benchmarking of a micro gas turbine model integrated with post-combustion CO2 capture

摘要: Abstract The deployment of post-combustion CO2 capture on large-scale gas-fired power plants is currently progressing, hence the integration and requires a good understanding operational requirements limitations to support this effort. This article aims assist research in area, by studying micro gas turbine (MGT) integrated with an amine-based unit. Both processes were simulated using two different software tools –IPSEpro Aspen Hysys, validated against experimental tests. MGT models benchmarked at nominal condition, then extended part-loads (50 80 kWe), prior their plant flue concentrations between 5 10 mol%. Further, performance when exhaust gases recirculated was assessed. Exhaust recirculation increases concentration, reduces flowrate specific reboiler duty. benchmarking revealed that IPSEpro model can be easily adapted new cycle modifications since temperatures rotational speeds respond reaching temperature limits; whilst detailed rate-based approach for Hysys resulted closely aligned simulation results data.
