Rice U. team seeks to optimize CO2 removal from power plant
emissions
In some of the first results from a federally funded
initiative to find new ways of capturing carbon dioxide (CO2) from coal-fired
power plants, Rice University scientists have found that CO2 can be removed
more economically using “waste” heat — low-grade steam that cannot be used to
produce electricity. The find is significant because capturing CO2 with
conventional technology is an energy-intensive process that can consume as much
as one-quarter of the high-pressure steam that plants use to produce
electricity.
