In order to reduce column height and the number of internals in a column, it is often advantageous to combine different internals into a single, combined unit.
For applications in certain columns, it is necessary to load several packed bed stages with different liquids. Between such column stages there is both a support grid for the packing and a collecting tray for the down flowing liquid. RVT's Combi element combines these functions into one part. Additional advantages are low pressure drop and very low weeping rates. It is recommended to put the Combi element onto a ring channel inside the column. Depending on column diameter, additional support beams may be necessary.
