REGENERATIVE REMOVAL OF SO2 AND NOX FOR A 150 MWE POWER-PLANT IN AN INTERCONNECTED FLUIDIZED-BED FACILITY

In the NOXSO process a regenerable sorbent is used that removes SO2 an d NOx simultaneously from flue gas generated during the combustion of coal. In this process the sorbent needs to be transported between adso rber and regenerator. For this purpose it is common practice to use a solids circulation system consisting of non-mechanical valves and conv eying lines. In this paper the use of an Interconnected Fluidized Bed (IFB) reactor system is proposed and evaluated. The IFB-NOXSO process is designed for the removal of NOx and SO2 from a flue gas stream orig inating from a 150 MWe power plant. The IFB reactor consists of multip le reactors that are constructed in one vessel and connected by means of orifices and weirs. It is shown that the IFB reactor can be success fully used in the NOXSO process.
