Air Products’ Advanced Oxyfuel Process for CO2 Capture
It is nice to see that Air Products has discovered a way for removing mercury and acid rain components from coal-fired electrical plants and other coal-burning facilities. I wonder how practical this will be? Air Products is certainly a very capable and innovative company. From Yahoo News:
“Air Products is a world leader in the development of oxyfuel technology. World scale air separation units (ASU) are required for oxyfuel CO2 capture projects, and Air Products is a proven supplier of this scale of cryogenic air separation plants. Additionally, Air Products’ CO2 purification process uniquely removes sulphur oxides, nitrogen oxides, and mercury during the compression process. CO2 purification and compression is important for the transport and geological storage of CO2 capture projects. The CO2 purification and compression system must be designed to minimize power consumption while meeting the purity specifications for the CO2.”
I would welcome any discussion of the merits of this system for cleaning up the products of burning coal. It purports to clean up much more than CO2 emissions. While there have been plenty of stories about how “clean coal” is a myth, I’d like to think that each case will be judged on its merits. So, what do people think? Thanks for reading.
