Rate-Based Modelling of Plate-Packed Heat Integrated Distillation Columns

TechnipFMC is pushing innovations to reduce the emissions of ethylene plants separations. This development is also driven by customer demands. They face increasingly strict legislation on \ce{CO2} emissions. Separation in distillation columns is one of the major energy intensive unit operations in an ethylene plant, and increasing their...

Numerical analysis of natural convection with conjugate heat transfer in coarse-grained porous media

We report numerical simulations of fluid natural convection with conjugate heat transfer in a bottom-heated, top-cooled cubical cavity packed with relatively large (d/L=0.2) solid spheres in a Body Centred Tetragonal (BCT) configuration. We study largely varying solid-to-fluid thermal conductivity ratios between 0.3 and 198, for a fluid...

Predicting the Liquid Phase Mass Transfer Resistance of Structured Packings

Published correlations for estimating the liquid phase mass transfer coefficients of structured packings are compared using experimental evidence on the efficiency of Montz-Pak B1–250MN and B1–500MN structured packings as measured in total reflux distillation tests using the chlorobenzene/ethylbenzene system at two operating pressures. Large...
