Summary:For the first set of test runs, additional changes were made to the tower internals. ULTRA-FRAC trays have astonishingly high capacities. In the 1992 column revamp from dual-flow to ULTRA-FRAC trays, the tower was equipped with six elements per tray. The reboiler was incapable of flooding such a tower (and the condenser would have been incapable of condensing the vapor, if it could have been flooded).
