Oc. Snip et al., REGENERATIVE REMOVAL OF SO2 AND NOX FOR A 150 MWE POWER-PLANT IN AN INTERCONNECTED FLUIDIZED-BED FACILITY, Chemical Engineering Science, 51(10), 1996, pp. 2021-2029
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.
