Development of soft-sensor for solvent dehydration tower

Fifth World Congress on Intelligent Control and Automation (IEEE Cat. No.04EX788), 2004
A soft-sensor using measurement of temperature distribution along the column to predict the compositions of the distillate and bottom products of the solvent dehydration tower is developed. With the distributed control system and offline measurement of the compositions, a recursive least-squares method is proposed to automatically correlate the ...

Module arrangement for solvent dehydration with silica membranes

Desalination, 2004
Abstract This simulation study investigated the influence of operating parameters and module and system design on performance and cost of pervaporation modules. It was based on isopropanol dewatering measurements with silica membranes and different types of methods to calculate heat and mass transfer resistance. It was shown that conventional modules

Revision Myringoplasty with Solvent‐Dehydrated Human Dura Mater (Tutoplast)

Otolaryngology–Head and Neck Surgery, 2001
OBJECTIVESSeveral grafting materials have been used in the reconstruction of the perforations of the tympanic membrane. The use of dehydrated dura homografts as a substitute for the tympanic membrane has not been fully documented. On the other hand, revision surgery is more critical in terms of patients' expectations.

A novel hydrophilic polymer membrane for the dehydration of organic solvents

European Polymer Journal, 2006
Abstract Novel hydrophilic polymer membranes based on cross-linked mixtures of poly(allylamine hydrochloride)–poly(vinyl alcohol) are developed. The high selectivity and flux characteristics of these membranes for the dehydration of organic solvents are evaluated using pervaporation technology and are found to be very promising when compared to ...

CONCENTRATION OF BIOETHANOL AND DEHYDRATION OF ORGANIC SOLVENTS BY POROUS MEMBRANES

Journal of Porous Media, 2015
In order to obtain higher membrane performance in the concentration of bioethanol and dehydration of organic solvents, porous poly[1-(trimethylsilyl)-1-propyne] (PTMSP) and porous chitosan membranes, respectively are applied to a temperature-difference controlled evapomeation (TDEV) method in which a temperature difference between the feed solution and
