Se ha propuesto y puesto en práctica una nueva metodología de aprendizaje basado en problemas en una asignatura de carácter experimental en la carrera de ingeniería química en la Escuela Técnica Superior de Ingeniería de la Universidad de Sevilla (España). La metodología se basa en el trabajo con grupos reducidos y aprendizaje basado en...

The inclusion of membrane-based oxygen-fired combustion in power plants is considered an emerging technology that could reduce carbon emissions in a more efficient way than cryogenic oxygen-fired processes. In this paper, a techno-economic assessment was developed for a 863 MWₑₗ,ₙₑₜ power plant to demonstrate whether this CCS technique results...

Historically, the emission of particles from clinker kiln stacks has been one of the main environmental concerns in cement manufacturing processes. Up to now, environmental regulations have only focused on determining and controlling filterable particulate matter (FPM) in industrial emission sources. However, in recent years a growing interest...

Oxygen transport membranes (OTM) are a promising alternative to conventional systems of air separation based on cryogenic distillation for oxy-fuel combustion power plants. In this work, a systematic study of the thermochemical stability of La0.6Sr0.4Co0.2Fe0.8O3 (perovskite-type) and cobalt doped Ce0.9Gd0.1O (fluorite-type) is proposed. The...

The exponential growth of greenhouse gas emissions and their associated climate change problems have motivated the development of strategies to reduce CO2 levels via CO2 capture and conversion. Reverse water gas shift (RWGS) reaction has been targeted as a promising pathway to convert CO2 into syngas which is the primary reactive in...

Partial oxy-combustion is proposed as a new carbon capture concept based on the use of oxygen-enriched air as an oxidizer instead of air during the combustion stage followed by a CO2 chemical absorption. This novel approach has showed potential advantages compared with other CCS technologies that may lead to a further reductions of the energy...

This work provides a wide overview of the state-of-art of the CO2 chemical absorption applied to Carbon Capture and Storage (CCS) technology. The objective is not only to provide the current status of the technology and the research and development activities carried out towards its deployment in the CCS field, but also to identify the future...

Anthropogenic CO2 emissions are considered the major contributor of greenhouse gas emissions worldwide. The mitigation of this kind of CO2 emissions relies on a portfolio of alternatives where CO2 absorption appears as the nearest approach to be applied at industrial scale. Researchers have been focused on developing new formulations of...
