Removal of fine particles by heterogeneous condensation was investigated experimentally for the double-alkali desulfurization process in this paper. A supersaturated vapor phase, necessary for condensational growth of fine particles, was achieved in the SO2 absorption zone by adding steam in the gas inlet and between the pieces of rotating-stream-tray, respectively. The influences of temperature of...
A new kind of venturi-swirler-combined scrubber was developed. This venturi-swirler-combined scrubber is composed of shuttle-typed components and swirler. These shuttle-typed components were assembled to comprise a honeycomb-typed structure gas passages similar to a contraction section, a throat section and an expansion section of venturi. By Sodium calcium Dual alkali scrubbing desulphurization method,...
Potassium Ferricyanide is produced by reducing reaction of potassium ferricyanide by reducing sugar, then it reacts with iron(III) chloride to obtain Prussian blue, whose intensity is the linear with content of reducing sugar. The optimum conditions for color reaction were investigated, and the results shows that it exhibits good linear relationship within 0.8–4µg/ml, molar absorption coeffcient is...
