New solvent for CO2 capture

Before I file my fatty alcohol article for ICIS Chemical Business today…here is an interesting development on carbon capture technology coming from German companies RWE, BASF and Linde.

The companies claimed that new chemical solvents can increase efficient separation of carbon dioxide from flue gas by being able to reduce energy input by 20%. The new solvents also feature superior oxygen stability, which reduces solvent consumption significantly.

The solvents were tested since 2009 in a pilot plant at RWE’s Niederaussem power station near Cologne.

The partners plan for a demonstration and large-scale power plants. First demonstration plants are scheduled to come on stream in 2015, and CO2 capture is expected to be used commercially in coal-fired power stations by 2020.

The technology is expected to allow more than 90% of the CO2 contained in the waste gas of a power plant to be captured for subsequent sub-surface storage or for chemical use such for fertilizer manufacture.

RWE Power will spend EUR9m ($11.6m) on the development project.
