US News : "Kemper's two gasifiers convert soft lignite coal mined at the site into a synthetic gas using high pressure and heat. The tubes broke March 9 in a cooling unit that reduces the heat of the gas that comes out of one gasifier before piping it into a chemical plant that removes carbon dioxide and other chemicals. The gas is then burned in turbines to generate electricity.
Spokesman Jeff Shepard said the company is working on restarting the second gasifier. The first one continues to run.
Kemper is designed to capture 65 percent of the carbon dioxide from the burning coal, releasing only as much of the climate-warming gas as a typical natural gas plant does."
