Initial Oxy-firing Co_2 Capture Testing Completed

摘要

Babcock & Wilcox recently concluded initial testing of its oxy-firing process and is currently analyzing the results. Although a full report on the results will not be available until early next year, B&W has issued preliminary findings. The tests were conducted at the Babcock & Wilcox Clean Environment Development Facility in Alliance, Ohio, by B&W and Air Liquide beginning in late 2007. The facility is essentially a mini power plant that does not generate electricity. Dozens of research and development programs are underway in the U.S. and worldwide testing a variety of approaches for capturing carbon dioxide from coal plants. Whereas some approaches capture CO_2 on a post combustion basis using amines or ammonia, another approach-oxy-firing-captures a highly concentrated stream of CO_2 in the boiler.
