Patented solution to reduce overall height and number of components in the column
In processes where multiple packed beds are required in the column, a support grid for the packings together with a collecting tray to collect the liquid between the beds are used. RVT's patented Combi element combines the supprot grid and collection tray in one unit.
The Combi element reduces the overall height of the column. Other advantages are the relatively low pressure loss and the efficient collection of the liquid.
