Oxycombustion Projects, to Enable CO2 Capture, Announced

DOE announced today that they had selected two projects to demonstrate "oxycombustion".  In an oxycombustion-based power plant, oxygen rather than air is used to combust a fuel resulting in a highly pure carbon dioxide (CO2) exhaust that can be captured at relatively low-cost and sequestered. No commercial oxygen combustion power plants are operating today, due mainly to the high cost of producing oxygen. Significant reduction in the cost of oxygen compared to today’s best cryogenic technology is a key requirement to making the oxycombustion power plant a viable future option.

The two projects selected for this demonstration are:

• Babcock and Wilcox (B&W)—B&W and its team will conduct five-million Btu per hour pilot-scale tests across a range of coal types including: Eastern bituminous coal, Power River Basin pulverized coal, sub-bituminous coal, and lignite coal in wall-fired and cyclone boiler configurations. B&W’s project expects to demonstrate that those cyclone boilers retrofitted with oxycombustion technology will demonstrate a cost-effective approach for CO2 capture coupled with much lower nitrogen oxide emissions.
• BOC Group, Inc.—The BOC Group plans to capture CO2 by combining oxycombustion technology with flue gas recycle in a process that replaces combustion air with a mixture of oxygen and recycled flue gas to produce a carbon dioxide-rich flue gas for sequestration.  To reduce the cost of oxygen production, BOC plans to apply its CAR (Ceramic Autothermal Recovery) oxygen production process that uses the mineral Perovskite to absorb oxygen and subsequently release it in a circulating fluidized bed and pulverized coal pilot-scale firing configuration.

Under separate programs DOE is developing membrane process for air separation as opposed to the conventional cryogenic methods.

Hi, i want know more about oxycombustion, how do it, what I need, for what and which are the conditions. Thank you for everything

I'm working on a green house project. I'm really interested by this Oxycombustion Projects.
thanks a lot!
