Effects of water on steam rectification in a packed column

Chemical Engineering Research and Design, 2011
Abstract The effects of water on steam rectification, i.e., multi-stage saturated steam distillation, were investigated in a packed column. N-octane–p-xylene and 1,3,5-trimethylbenzene–1,2,4-trimethylbenzene were used as test systems. Both binary systems are nearly ideal systems and insoluble in water, thus the effects of water in steam rectification

Rectification column: criteria of efficiency [PDF]

Technical Transactions. Mechanics = Czasopismo Techniczne. Mechanika, 2016
In the paper analysis of the factors influencing the efficiency of the rectification process is provided. The authors show that existing dependences, equivalent to HETP, cannot be used for calculating rectification plate columns and columns with vortex nozzles, in which the coefficients of mass transfer are substantially dependent on the irrigation ...

Intermediate irrigation of complex rectification columns

Chemistry and Technology of Fuels and Oils, 1969
1. The use of “blind” trays in complex columns is not advantageous since, in this case, the connection of the sections with respect to the liquid flow is made difficult, and there is a lowering of the operating flexibility of the unit, with regulation of different industrial indices (removal and quality of distillates, degree of heating of the raw ...

Cap-grid plates in rectification and absorption columns

Chemistry and Technology of Fuels and Oils, 1968
1. Cap-sieve plates are highly effective contact devices. 2. The capacity of cap-sieve plates is higher than that of cap plates and lower than that of sieve plates. 3. Cap-sieve plates ensure stable operation under considerable variations in load and, hence, are broad-range plates. 4. Owing to the special features

Design of packed distillation columns. III. Rectification film resistances in a packed column

Journal of Applied Chemistry, 1951
AbstractData are presented which lead to the conclusion that the liquid‐film resistance was the controlling resistance in rectification of a binary system carried out in a particular packed column. This confirms the conclusion reached by other workers on similar packed columns.
