Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Packed columns are considered useful to a great extent in the distillation of
natural gas, and liquid volume fraction is a critical parameter for their design. This
study aimed to develop a geometrical model of a packed column with one cone spray to
simulate the injection. Here, the commercial software FLUENT 6.3 was employed.
CFD simulations using the mixture model coupled with several turbulence models were
used to analyze the porosity effect on the fluid profiles. The results show that the
decrease of the packed porosity resulted in a greater dispersion of the liquid, indicating
the anisotropic behavior in the bed. Furthermore, the effect of different turbulence
models was analyzed in order to study the atomizing of the liquid phase accurately. The
numerical results were obtained to provide further insight into the mechanism of the
distillation with volatile components.
