Dehydration of aqueous ethanol

Energy in Agriculture, 1987
Abstract Upgrading of aqueous alcohol to anhydrous ethanol may be accomplished using a packed bed adsorption process, in which cracked grain corn is the adsorbent. A 0.35 m diameter by 3.0 m dehydration column was designed and constructed on the basis of data obtained in a series of bench-scale experiments.

Silica Derived Membranes for Dehydration of Aqueous Ethanol [PDF]

, 2023
Molecular sieving silica (MSS) membranes are novel amorphous microporous membranes with well defined pore structures. Current industrial applications of MSS membranes were used for recovery or purification of hydrogen gases. The superior separation performance of silica based membranes had raised the interest even further in applications of dehydration

Ethanol dehydration by extractive distillation

Journal of Chemical Technology & Biotechnology, 1992
AbstractExperiments and process simulation enable favourable operating conditions to be determined for the extractive distillation of ethanol—water, with ethylene glycol as a solvent. The solvent molar rate to feed molar rate ratio S/F = 0·6 and the reflux ratio R = 0·5 were determined in order to achieve at least 99·5 mole % purity of ethanol.

Electronic mechanism of catalytic dehydration of ethanol

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1983
1. On the basis of an analysis of the distribution of the deforming force among the atoms and bonds during electronic transitions it was shown that the dehydration of ethanol is promoted by capture of an electron from the catalyst by the adsorbed molecule. 2.

Optimization of hybrid ethanol dehydration systems

Chemical Engineering and Processing: Process Intensification, 2002
Abstract Hybrid ethanol dehydration systems are modeled and optimized using MINLP. The systems consist of a distillation column for approaching the ethanol/water azeotrope and of a pervaporation unit for producing pure ethanol. The optimal design and operating parameters including number of trays, feed location, reflux ratio, number of membrane ...

Dehydration of ethanol on filtrol and modified filtrols

Materials Chemistry and Physics, 1986
Abstract The commercially available clay cracking catalyst filtrol (SR grade 63) and its heat treated forms have been characterized by chemical, spectral, X-ray and surface measurement methods. The decrease in pore volume of filtrol during heat treatment is accounted for by the phase transition in the system. The catalytic activity of filtrol and its

Heat Integrated Ethanol Dehydration Flowsheets

Separation Science and Technology, 1995
Abstract A theoretical evaluation of heat-integrated heterogeneous-azeotropic ethanol-water distillation flowsheets is presented. Simulations of two column flowsheets using several different hydrocarbon entrainers reveal a region of potential heat integration and substantial reduction in operating energy.
