Abstract

MINKhiGP has designed a new cocurrent valve tray whose structural modifications include changing the position of the arc-shaped baffle so that one can regulate the proportion of the gas streams and alter the hydrodynamic conditions in the contact zone. A modified tray in which the bent part of the arc shaped baffle bears holes provided with guide plates is also presented. The working characteristics of the two valve trays are compared and it is found that escape is less marked for a tray with compensated cocurrent than for tray with standard valves. The principle of compensated cocurrent on the valve trays makes it possible to intensify mass transfer in the operations of petroleum refining plants.
