The CO
2
Capture Sub-Programme has achieved
the following:
Solvent technology
• For the new class of precipitating absorbents,
fully range vapour-liquid-solid equilibrium
measurement has been carried out, and
the region for crystal (figure below)
formation and dissolution has been studied.
A preliminary study of the integration of
a precipitating CO
2
capture in an NGCC
power plant in Task 1.6, has shown an 11%
reduction in capture unit penalty compared to
an MEA based capture unit. Oral presentation
at PCCC3 covering Integration of precipitating
capture in an NGCC power plant.
Crystallized sample SEM imaging.
• PhD candidate Nina Enaasen Flø defended her
PhD successfully on September 4, 2015.
• Dynamic model validation paper has been
published in the International journal of
Greenhouse Gas Control. The paper with time
constants at the Tiller pilot is submitted to
Computers and Chemical Engineering journal
in May. Oral presentation at TCCS-8 covering
the journal publication about dynamic model
validation was held.
Innovative membrane technologies
• Up-scaled asymmetric tubular membranes
for pre-combustion CO
2
capture and
steam-methane-reforming applications are
fabricated (figure below), and sealed with
high-temperature glass-ceramic seal. First
flux measurements of the tubular membrane
up to 1000 °C are successfully perfomed.
Asymmetric tubular membranes.
• Peer-review dissemination: One paper
accepted on Hydrogen Transport Mmembrane
flux, one paper submitted on long-term flux
testing, one oral presentation at international
conference
• Studies on understanding the effect of
nanoparticles in a polymer based membrane
for post-combustion CO
2
separation continues
in the KPN project HyMemCOPI.
Flame (red surface) propagates in non-perfectly
mixed reactants (colorscale) flowing in a duct.
