Rather than compulsory directions, a collection of techniques ispresented to guide the user. Emphasis is placed on principlesrather than on specific steps.

This procedure covers continuously operated tray distillationcolumns. The tray columns include all types of trays, with orwithout down comers for liquid. Testing of auxiliary equipment isnot included, even though it may limit column capacity. Otherestablished procedures are available for testing auxiliaryequipment.

Batch distillation columns are covered in that their performancecan be tested best by running them under steady state conditions,either at total reflux or with the overhead returned to the kettlecontinuously. The principles outlined herein for continuous columnswill then apply.

Purpose

This testing procedure offers methods of conducting andinterpreting performance tests on tray distillation columns. Suchtests may be made to accumulate reliable data in one or more of thefollowing areas of interest: try efficiency, capacity limitations,energy consumption, or pressure drop considerations. These data areuseful for troubleshooting, for debottlenecking, for new designs,for correlations, and for determination of the operating range of acolumn as well as the optimum operating conditions. These data mayalso be required for an “acceptance test”.
