Support new packed bed reactor in EE and sizing methods. The model will replicate most of the features of the Packed Tower model, but removing options specific for mass transfer separation columns and adding options relevant for reactors. There should be a field to specify catalyst packing type and specific price. Sizing methods for equilibrium or balanced based simulator models will use the space velocity as weight hourly space velocity (WHSV) and bed density entered by the user to calculate volume and then derive geometry. For rigurosa rate-based reactors models, sizing will read the dimensions from the simulator data.
