In the Nuon/Vattenfall CO2 Catch-up project, a pre-combustion CO2 capture pilot plant was built and operated at the Buggenum IGCC power plant, the Netherlands. The pilot consist of sweet water-gas shift, physical CO2 absorption and CO2 compression. The technology performance was verified and validated models were obtained. This paper describes the validation of a WGS reactor model and the excel...

UNLABELLED The early atmospheric detection of carbon dioxide (CO2) leaks from carbon capture and storage (CCS) sites is important both to inform remediation efforts and to build and maintain public support for CCS in mitigating greenhouse gas emissions. A gas analysis system was developed to assess the origin of plumes of air enriched in CO2, as to whether CO2 is from a CCS site or from the oxi...

Reductions in the cost of technologies as a result of learning-by-doing, R&D investments and other factors have been observed over many decades. This study uses historical experience curves as the basis for estimating future cost trends in CO2 capture technologies applied to four types of electric power systems: pulverized coal (PC) and natural gas combined cycle (NGCC) plants with postcombusti...

avoidance cost of carbon capture from pulverized coal plants. To investigate this possibility, a technoeconomic oxyfuel model was constructed. The model was exercised to explore the effect on CO2 avoidance cost and LCOE from several key parameters, namely: CO2 purity, oxidant purity, CPU and ASU performance and cost, coal composition, and geographic location. Monte-Carlo techniques were then us...

Introduction of closed cycle gas turbines with their capability of retaining combustion generated CO2 can offer a valuable contribution to the Kyoto goal and to future power generation. Therefore research and development work at Graz University of Technology since the nineties has led to the Graz Cycle, a zero emission power cycle of highest efficiency. It burns fossil fuels with pure oxygen wh...
