WASHINGTON, D.C. — The U.S. Department of Energy announced Wednesday that millions of dollars in federal funding could help the world’s largest lime kiln, located in Ste. Genevieve, to nearly eliminate greenhouse gas emissions.
A project team led by the University of Illinois at Urbana-Champaign (UIUC) (Champaign, IL) aims to advance the technology of carbon capture with a front-end engineering design (FEED) study to retrofit the Holcim’s Ste. Genevieve cement manufacturing facility in Bloomsdale, Missouri, which is the largest single lime kiln in the world.
The detailed engineering and design work will support development of a detailed cost estimate for retrofitting the existing host site with a carbon capture plant.
The design will employ Air Liquide’s CryocapTM FG system, which combines pressure swing adsorption to preconcentrate the CO2 in the feedstream with cryogenic refrigeration technologies to purify and compress the CO2 product, thereby achieving high CO2 capture rates with high CO2 purity. The capture technology has the ability to achieve 95 percent capture from flue gas.
