Abstract:
The presentation first gives an overview of the SINTEF group and the on-going CCS research at SINTEF Energy Research being one of eight research units within the SINTEF group. The SINTEF group is the largest independent, contract research organization in Scandinavia, and it is the largest R&D performer on CCS within the two latest framework programmes of the European Union (FP6&7). SINTEF Energy Research has been part of and coordinated large European CCS projects (ENCAP, DYNAMIS, ECCO and DECARBit). It is also the host institution of the BIGCCS centre, one of the national key laboratories designated Centers for Environment-friendly Energy Research established by the Norwegian government. The BIGCCS center has 22 partners from academia, research institutes and industry, and a budget of around 425 million RMB over 8 years (2009-2017). The centre covers capture, transport and storage of CO2.
Next, the presentation will go in more detail and present published results from the following topics:
- CCS power cycles evaluation and integrated assessment: Concept for low-temperature syngas separation and CO2 capture in IGCC; Integration of power cycles and post-combustion capture systems including possible efficiency improvements by exhaust recirculation. (References [1] – [3]).
- CO2 pipeline transport: New evaluation methodology for pipeline integrity and fracture control under possible accidental failure causing depressurization, strong cooling and material brittleness. (References [4] – [5]).
- Oxy-combustion in CCS processes: Radiative heat transfer and soot formation in diffusion flames in oxy-fuel atmosphere; Instabilities in pre-mixed oxy-combustion; HiPrOx high-pressure oxy-combustion test rig. (References [6] – [9]).
- Combustion of hydrogen-rich fuels for IGCC applications with special emphasis on direct numerical simulations (DNS) of relevant canonical configurations as a tool for increasing the knowledge about and improve challenging combustion processes. (References [10] – [11]).
- Small-Stokes-number particle deposition on super-heater tubes using Lagrangian particle tracking in high-definition direct numerical simulation with the immersed boundary method. (References [12] – [13]).
Most attention will be given to the topics 3, 4 and 5.
