Mass Transfer in Binary and Ternary Distillation by a Packed Column with Structured Packing.

Comaprison of Mass-Transfer Efficiencies of Scc and Structured Packing

In a previous paper, pressure drop, flooding and mass-transfer characteristics of a novel pilot-scale distillation column called spinning cone column (SCC) were presented. Here, we present the result of comparison of mass-transfer efficiencies of SCC and structured packing. Comparison of SCC and structured packing mass-transfer characteristics show that the gas and liquid-side height of transfe...

Heat Transfer in a Column Packed With Spheres

The purpose of the study is to investigate average and local surface heat transfer coefficients in a cylinder packed with spheres. Here the term «local» applies to a single sphere within the bed. Averages are derived from the sixteen different spheres that were instrumented and distributed throughout the bed. The experimental technique consisted of introducing a step - wise change in the temper...

HETP Evaluation of Structured and Randomic Packing Distillation Column

Packed columns are equipment commonly found in absorption, distillation, stripping, heat exchangers and other operations, like removal of dust, mist and odors and for other purposes. Mass transfer between phases is promoted by their intimate contact through all the extent of the packed bed. The main factors involving the design of packed columns are mechanics and equipment efficiency. Among the...

Investigation of Packing Effect on Mass Transfer Coefficient in a Single Drop Liquid Extraction Column

A Modified Model of Computational Mass Transfer for Distillation Column

The Computational Mass Transfer (CMT) model is composed of the basic differential mass transfer equation, closed by auxiliary equations and the appropriate accompanying CFD formulation. In the present modified CMT model, the closing auxiliary equations in the c2 1c model given by Liu (2003) are further simplified for reducing the computational complication. By this model, the turbulent mass tra...
