Blog: IMPACTS and BIGCCS visit partners in Bochum in Germany

Ruhr Universität Bochum has over 40,000 students and 4,500 permanent employees. Here you can study everything from film, language and African culture, through history, engineering and astrophysics, to gases’ thermophysical properties. And precisely because of this last thing were participants of the EU project IMPACTS gathered in Bochum two days in the end of October.

The host for the visit was Professor Roland Span, professor within the field called thermophysical properties.

Late October this year, the IMPACTS project met for a technical workshop and board meeting in Bochum, and we had the opportunity to visit his very interesting laboratories.

The IMPACTS project concerns pipeline transport of CO2 as an integral part the CO2 capture and storage concept. During such transportation, knowledge of CO2 gas properties such as thermal conductivity, viscosity, pressure and temperature of transition between the phases (solid-liquid-gas) and other are important and essential.

This has been Professor Roland Spans’ area of research for many years, both in determining these properties accurately in the laboratory and predicting the properties by developing equations that say something about how CO2 will behave under different pressures and temperatures.

Professor Span is also one of the researchers behind the Span-Wagner equation of state. This is an equation which predicts the behavior of pure CO2 very accurately, and which is widely used for us who work with CO2 capture, transport and storage.

Professor Roland Span and his research group are partners of the IMPACTS project and they contribute with both experimental and theoretical research.

IMPACTS is a large European research project under the 7th Framework Programme coordinated by SINTEF Energy Research. The project deals with the transport of CO2 in pipelines as an intermediary between CO2 capture and CO2 storage. More specifically, the project will work on identifying how the impurities of gases other than CO2 affect how the CO2 behaves during transport in a pipeline. This is important to know in order to avoid gas mixtures that may form solid phases which could block the pipeline, or mixtures which provide such high pressure that the pipe can crack open.
Several of SINTEF researchers participating in the IMPACTS project are also key researchers in BIGCCS and have gained significantly from research in the center. Professor Roland Span also contributes to the BIGCCS centre.
