Forward and inverse problems of supercritical extraction of oil from polydisperse packed bed of ground plant material
Theoretical Foundations of Chemical Engineering - Tập 48 - Trang 39-47 - 2014
A. G. Egorov, A. A. Salamatin, R. N. Maksudov
The problem of determining the overall extraction curve for the supercritical fluid oil extraction from polydisperse layer of ground oilseed granules was solved analytically using the shrinking core model. The functional dependence obtained for bi-disperse approximation of the packed bed describes the results of known experiments with high accuracy. Ways to solve the inverse problem of determining...... hiện toàn bộ
Linear models of three-phase extraction processes

Rational Use of Multicomponent Brines Extracted Together with Oil
Theoretical Foundations of Chemical Engineering - Tập 54 - Trang 756-761 - 2020
A. D. Ryabtsev, N. P. Kotsupalo, A. A. Kurakov, N. M. Nemkov, A. G. Vakhromeev
The expediency of using multicomponent brines extracted together with oil (gas) as the raw material for obtaining lithium products and products required for oil fields has been shown. After the lithium concentrate is obtained, the brine is used for obtaining bromine, calcium bromide, magnesium oxide and chloride, and sodium chloride for the electrochemical obtainment of reagents for technological ...... hiện toàn bộ

Electrochemical production of aluminum hydroxide from kaolins
Theoretical Foundations of Chemical Engineering - Tập 50 - Trang 806-811 - 2016
T. Yu. Eranskaya, V. S. Rimkevich
It has been shown that an electric spark discharge in saturated alkaline solution acts as a catalyst of ionization during the decomposition of kaolinite into aluminate and silicate components. The production of aluminum hydroxide from KM-1-grad kaolin (Chalgansk deposit) is 24.8–37.2% of the estimated value.
Optimization of the Production Process of Biologically-Active Betulin Diacetate from Raw and Activated Birch Bark
Theoretical Foundations of Chemical Engineering - Tập 52 - Trang 664-669 - 2018
S. A. Kuznetsova, B. N. Kuznetsov, Yu. N. Malyar, E. S. Skurydina, G. P. Skvortsova, R. Z. Pen, N. V. Chesnokov, O. A. Khanchich
The effect of the conditions of the acetylation process of raw and activated birch bark on the yield and composition of the products is investigated. The structure of biologically active betulin diacetate (BDA) is confirmed with physicochemical methods. The optimal regimes of the one-step original method for the production of BDA from raw and activated birch bark are established using the experime...... hiện toàn bộ
