Improvement of Fixed Valve Trays

  • Published:
Chemical and Petroleum Engineering Aims and scope

The results of a study of hydrodynamics and mass transfer on fixed valve trays are presented along with an improved valve-vortex contact device. The fields of liquid and gas velocities, as well as the structure of the gas content in the liquid layer on the tray, were established through experimental research and numerical simulation in the OpenFOAM program. The dependence between the amplitude of fluctuations of the mixture on the tray, on the gas flow rate for the presented contact devices, is obtained. The circulation flows of the liquid on the tray are established, the average surface diameter of the gas bubble is determined. Experimental data on the value of the mass transfer coefficient and efficiency are presented. It has been established that the valve-vortex tray has the highest efficiency and capacity for liquid and gas.
