|Air Products’ Proprietary Technology Onstream at World’s Premier Demonstration of Oxyfuel CO2 Capture and Storage at Vattenfall|
|Thursday, 05 May 2011 01:00|
On May 5, 2011 Air Products announced its proprietary carbon dioxide (CO2) capture, purification and compression system at Vattenfall AB's research and development facility in Schwarze Pumpe, Germany is onstream and performing a key role in the world's premier demonstration of oxyfuel carbon capture.
Vattenfall, one of Europe's leading energy companies, held an inaugural ceremony today at the facility which hosts what is viewed globally as the preeminent CO2 oxyfuel project. Air Products’ technology is focusing specifically on the purification and compression of oxyfuel combustion flue gas during the scheduled three year demonstration project.
“At Air Products we have been engaged in innovative oxyfuel solutions for decades. Through working with leading partners all over the world, one of our goals is to develop technologies that reduce the cost of capturing CO2,” said David J. Taylor, vice president - Energy Businesses at Air Products. “In working with companies like Vattenfall, which is leading the field in CO2 capture solutions, we can help validate our unique CO2 purification and compression capabilities. These technologies have the potential to fulfill environmental targets around the world.”
Hubertus Altmann, head of the Power Plant Unit of Vattenfall in Germany is pleased with the transatlantic collaboration on this project. “Increasing efficiency is one of the crucial tasks when developing CCS (carbon capture and storage). In a few years, the technology will be competitive in the market and in order to reach that goal there remains a lot of R&D to be done. It’s important for international companies such as Air Products and Vattenfall to join forces and cooperate on projects like the one we are celebrating today,” said Altmann.
At the Schwarze Pumpe facility, Air Products will take flue gas directly off Vattenfall's 30 megawatt (MW) wall-fired boiler at the oxyfuel pilot plant. It will purify and compress the carbon dioxide to a purity acceptable for storage or enhanced oil recovery. Air Products' proprietary sour compression technology uses a staged compression process to optimize pressure, hold-up, and residence time to allow removal of impurities during the compression process. This allows cost savings in the oxyfuel combustion process and minimizes the concentration of acidic components, important in preventing corrosion during the CO2 storage process. This pilot will demonstrate the efficient purification of CO2, and removal of atmospheric gases, in particular oxygen. In addition, it will incorporate novel membrane technology, targeting carbon capture rates as high as 98 percent.

Vattenfall inaugurated the 30 MW pilot plant for carbon dioxide capture at its lignite coal-fired power plant at Schwarze Pumpe in September 2008. Based on the conclusions from this pilot plant, the next step will be to build larger demonstration power plants, for which feasibility studies have already been initiated and target on-stream status for 2015.
