Abstract

Vapor pressure date and vapor-liquid equilibria date at 1-30 m.m. pressure are presented for benzyl alcohol and benzyl-n-butyl ether system. Activity coefficients for the system are symetrical, the Margules constants ere A_1-2 = A_2-1= .301. HETP values observed at a condenser pressure of 1 m.m. for 1/4" and 3/4" Berl saddles, 1" Intalox saddles, Fibre Glass Combination packings # 076 and # 476, and a Knitted Wire Mesh pecking are presented as a function of the mass throughput and column pressure drop. At a condenser pressure of 1 m.m. the pressure drop per foot in terms of the mass throughput is observed for each packing. HETP values at high vacuum are greater than those observed in the same equipment at atmospheric pressure.
