Flooding Regimes for a Distillation Column with Structured Packing

  • Published:
Chemical and Petroleum Engineering Aims and scope

The critical parameters of vapor and liquid, corresponding to flooding of the distillation column, were measured experimentally (flooding means the process of partial suspension of liquid in a packing, accompanied by an exponential increase in the pressure drop and subsequent flooding of the vapor space between the packing and the liquid distributor). The experiments were carried out in a wide range of determining parameters: pressures and concentrations of the mixture, ratios of the mass vapor and liquid flows, geometric characteristics of the packing, and physical properties of Freons. The experimental results were processed in dimensionless coordinates and generalized by single dependence We = f(N), where the Weber number We is derived according to the vapor velocity in the packing cell, and the Froude number (included in complex criterion N) is derived by the average liquid velocity in the packing cell.
