By adopting the design of a counterflow spray tower, the desulphurization tower is provided with a smoke gas inlet at the middle part, provided with a smoke gas outlet at the top and sequentially provided with a defogging segment, an absorption segment, a temperature reduction segment and an oxidation pond inside from top to bottom, wherein a two-stage corrugated plate high-efficiency defogger is adopted on the defogging segment, and an automatic cleaning and spraying device is matched; a water spraying and washing layer and a cyclic absorbing and spraying layer are arranged on the absorption segment; the temperature reduction segment corresponds to the position of the smoke gas inlet; and an oxidation air distribution exhaust pipe and a pump agitating device are arranged inside the oxidation pond, a compressed air inlet, an ammonia water inlet and a circulation pump are arranged at the outer side, and an ammonium sulfate slurry pump is arranged at the bottom. The desulphurization tower combining by using the ammonia process can finish the smoke gas desulphurization process with high efficiency and energy saving, thereby having greater industrialized prospects.

Kinetics and reactor simulation for polyethoxylation and polypropoxylation reactions

Abstract: The kinetics of, respectively, polyethoxylation and polypropoxylation reactions in the presence of a hydrophobic starter and a basic catalyst are presented with a general approach based on the reaction mechanism. A general kinetic model and a simplified model useful to simulate the alkylene oxide consumption and the oligomers distribution in well-mixed semibatch reactors are presented. Kinetic laws and related parameters have been tested by simulating a spray tower pilot plant reactor with two alternative models considering the liquid in the drops emerging from the spray nozzle to be either stagnant or well mixed. The later possibility seems to be the correct one.
