Extraction of bituminous material from fossil organic matter using liquid carbon dioxide under liquid-vapour equilibrium conditions
Extracts from a peat, a low-rank coal and a bituminous oíl shale obtained with liquid carbon dioxide were studied by capillary gas chromatography-mass spectrometry and compared with those obtained by Soxhlet extraetion with n-hexane. Although the extraetion yields with liquid carbon dioxide were lower, the composition of the extraets, comprising mainly a large variety of linear and cyclic hydro...
متن کاملInvestigation of Mass Transfer Coefficient under Jetting Conditions in a Liquid-Liquid Extraction System
In this research mass transfer coefficient under jetting regime in different directions (from dispersed to continuous and continuous to dispersed phase) has been studied using an experimental setup. n-Butanol-succinic acid-water with low interfacial tension has been selected as experimental chemical system. The effects of various parameters such as jet velocity, nozzle diameter and the heig...
متن کاملLiquid - Liquid Extraction of 2, 3-Butanediol from Fermentation Broth
Recovery of metabolites from fermentation broth by solvent extraction can be used to optimize fermentation processes. End-product reutilization, low product concentration, large volumes of fermentation broth and the requirements for large bioreactors, in addition to the high cost largely contributed to the decline in fermentative 2, 3-butanediol production. Extraction can ...
متن کاملLiquid-Liquid Extraction of Gallium from Jajarm Bayer Process Liquor Using Kelex 100
The solvent extraction of gallium from a concentrated Jajarm Bayer process liquor containing 164.90 g/l of Na2O, 86.70 g/l of Al2O3 and 106.02 ppm of gallium was investigated using 10 vol.% Kelex100, a 7-alkyl substituted-8 hydroxyquinoline as an extractant, 10 vol.% etanol as a modifier and kerosene as a diluent. At (Vo :Va = 1.0:1.0) ...
متن کاملLiquid-liquid equilibrium data prediction using large margin nearest neighbor
Guanidine hydrochloride has been widely used in the initial recovery steps of active protein from the inclusion bodies in aqueous two-phase system (ATPS). The knowledge of the guanidine hydrochloride effects on the liquid-liquid equilibrium (LLE) phase diagram behavior is still inadequate and no comprehensive theory exists for the prediction of the experimental trends. Therefore the effect the ...
