摘要：
Separations processes and apparati capable of purifying thermally sensitive materials at high capacity. An apparatus having a rectification section (3) and a stripping section (4) with the stripping section (4) having a stripping tray (1020) with 5 to 50 % open area (1000), a pressure drop from 0.02 psi to 0.2 psi and a tray efficiency during operation of the column which is equal to or greater than 20%.
