4 July 2008 - Mitsubishi Heavy Industries (MHI) and E.ON Energie will jointly test technology for recovering carbon dioxide (CO2) from flue gas emissions from a coal fired power generation plant in Germany.
The CO2 recovery test plant to be added to E.ON Energie's existing plant will adopt MHI's technology for absorbing and desorbing CO2 from flue gas using its proprietary KS-1 solvent, and will be capable of capturing 100 tonnes of CO2 per day (flue gas flow rate: 20 000 m3 per hour).
The recovery plant operation will commence early in 2010. The various tests to be conducted at the plant will focus mainly on further reducing the amount of energy consumed to complete the CO2 recovery process.
One feature of MHI's CO2 recovery technology is considerably lower energy consumption compared with other processes. In Japan, a testing plant capable of recovering 10 tonnes of CO2 per day using MHI's process has been operating at a coal fired power generation plant in Nagasaki the Matsushima thermal power station of Electric Power Development Company Limited (J-POWER) since July 2006, and verification testing toward the establishment of the optimal recovery system is moving forward.
In the testing project in Germany, E.ON Energie will build, based on MHI's basic design, a CO2 recovery pilot plant including a flue-gas cooling tower, a CO2 absorption tower using the KS-1 solvent, and a CO2 desorption tower for separating the CO2 from the absorbent.
MHI will supply part of the facility equipment and the K-1 solvent. Testing with flue gas from coal-fired boilers will be conducted over a period of two years. E.ON Energie is expected to invest €10m ($15.7m) in the programme.
