【正文】 xture to repeat the process, and the feed port has the fresh raw materials , plete the benzene and chlorobenzene separation. Packed tower belongs to the differential contact type gasliquid mass transfer to packing as a gasliquid contact and mass transfer of basic liquid in the filler surface as a film flows from top to bottom, gas and liquid phase bottomup was continuous countercurrent flow, and the heat and mass transfer of gasliquid two ponent concentration or temperature along the height of a continuous change. Plate tower is a sequential contact of gasliquid mass transfer to tower plate as a basic ponent, gas from tower bottom upward to bubble live spray form, through the tower plate of the liquid layer, so that the gas liquid phase in close contact and mass transfer and heat transfer, twophase ponent concentration was a step change. Considering the plate tower as the ratio of packed tower stable performance, high efficiency, convenient installation and maintenance and low cost, the design of plate column.Plate is a plate tower main ponent, divided into a crossflow plate and counterflow plate two, industrial applications to crossflow plate, used a crossflow plate mainly bubble tower, tower, float valve tower. Sieve plate tower in relative phase load, efficiency, reliability and price was lower than the other two Tayou, therefore the design selection of sieve plate tower, its features are as follows: It has the advantages of simple structure, convenient manufacture repair。 Large production capacity, higher than the float valve tower。 Plate lower pressure drop, suitable for vacuum distillation。 Tower plate efficiency is high, but slightly lower than the float valve tower。 Rational design of sieve plate taco is highly flexible, only slightly and bubble tower。 Small aperture plate is
