Commercial demonstration of the NOXSO SO2/NOx removal flue gas cleanup system. Quarterly technical progress report No. 12, December 1, 1993--February 28, 1994

摘要

The NOXSO process is a dry, post-combustion flue gas treatment technology which uses a regenerable sorbent to simultaneously adsorb sulfur dioxide (SO2) and nitrogen oxides (NOx) from the flue gas of a coal-fired utility boiler. In the process, the SO2 is reduced to sulfur by-product and the NOx is reduced to nitrogen and oxygen. The objective of the NOXSO Demonstration Project is to design, construct, and operate a flue gas treatment system utilizing the NOXSO process. The project is presently in the project definition and preliminary design phase. The plant general arrangement has been revised to incorporate principles used in the design of fluidized catalytic cracking (FCC) plants. A NOXSO plant availability analysis was prepared using operating experience from the recently completed pilot plant as a basis. The impact of water desorption in the sorbent heater and water adsorption in the sorbent cooler has been quantified and incorporated into the NOXSO process simulator. NOXSO process economics has been updated based on the present design.
