Abstract
A process for desulfurization of fuel combustion gases and a new reactor wherein the primary flue gas stream containing sulfur oxides and alkaline oxide solids flows into the reactor vessel. A plurality of baffle columns is positioned at the top of the reactor vessel which serve to separate the primary stream into a plurality of first streams containing substantially all of the alkaline oxide solids and a plurality of second streams comprising substantially solids-free gas. The first streams are wetted after which they recombine with the second streams to produce reaction product sulfates and sulfites. The reaction product is substantially dry because the hot second streams cause evaporation of substantially all of the moisture from the wetted first streams.
