The Linde Group has entered into a technology partnership with Vattenfall Europe Technology Research GmbH for the development of carbon dioxide separation in coal-fired power stations.

The aim of the wide-ranging collaboration is to test the oxyfuel combustion process for lignite and anthracite, while also developing the technology for subsequent use in large power stations.

Tests are being conducted at the research facility for a coal-fired power station using carbon dioxide capture technology in Schwarze Pumpe in Brandenburg, Germany, recently officially inaugurated by Vattenfall.

Linde has built an air separation plant and a carbon dioxide liquefaction plant for the pilot power station, and is supporting Vattenfall through a technology partnership which will see the group provide extensive scientific and technical expertise, during the first trial phase to the end of 2011.

“This promising collaboration with Vattenfall can provide an important impulse to climate protection,” commented Dr Aldo Belloni, a member of the Executive Board of Linde AG.

“Our professed aim is to use our technologies to contribute towards a reduction in emissions. Our activities therefore range from continually improving the efficiency of our plants through CO2 separation technologies and adopting sensible recycling concepts to producing environmentally friendly fuels.”

At the research facility, a huge variety of tests and experiments will be conducted during the operation of the pilot plant. These will create a better understanding of the entire oxyfuel combustion process and of the reaction of individual components within the process chain.

Under the technology partnership too, Linde will take delivery from Vattenfall of around 4,000 tonnes of liquefied CO2 per annum from the research facility and market it. Both companies also intend to work together to develop further possible applications for the separated liquefied CO2 which is not required for the storage projects.

It was only in July this year that Vattenfall signed an agreement with Praxair Deutschland GmbH & Co. KG, to provide technology and engineering in the joint development of technology to reduce carbon dioxide emissions from coal-fired electricity generating power plants.
