Abstract:
This article is about the possibility of concentrating commercial coal phenol with a concentration of 99% by the weight method of rectification from the phenolic fraction of coal tar. The sufficiency of phenol is ensured by the kumol method, however, the consumption of phenol increases. Modeling of the vapor-liquid equilibrium of double and triple mixtures of components using the NRTL model showed the presence of the following positive homogeneous azeotropic mixtures: phenol-indane, phenol-indene.

Abstract:
In a series of two articles, the problems of azeotrope separation (part I) and the design of separation units (part II) were analyzed. The basic definition and equations of vapour-liquid equilibria for ideal and non-ideal systems, the importance of the activity coefficient calculation necessary for the analysis of non-ideal equilibrium systems, as well as theoretical aspects of azeotrope rectification and the determination of the optimal third component (modifier or azeotrope agent) are presented in the first part.

Abstract:
In the present work, an analysis of the mutual arrangement of a number of iso-manifolds in the concentration tetrahedron formed by the components of the separated mixture and an additional substance, an extractive agent, was carried out to estimate the possibility of separating three-component mixtures containing biazeotropic constituents by extractive rectification. The objects of research were four-component systems formed by ternary constituents (butyl propionate (BP) - propionic acid (PA) - butyl butyrate (BB), butyl propionate - propionic acid - butyric acid (BA), butyl butyrate - butyric

Abstract:
The composition of light pyrolysis resin was studied in detail and it was determined that mass fraction of aromatic hydrocarbons, especially benzene and toluene, is high compared to other hydrocarbons. The catalytic treatment was carried out with an aluminum complex catalyst based on toluene, synthesized in the laboratory, and the mass fraction of benzene in the light resin was increased. The optimal mode of the process corresponding to the maximum increase of benzene has been determined. At the next stage of the research, the benzene fraction was separated by rectification, and high purity be

Abstract:
In this work, the dynamic viscosity and density of three-component mixtures consisting of a binary azeotropic mixture of isopropanol-water and an extractive agent were investigated. Three points of the profile of concentrations in the liquid phase in the extractive separation column of isopropanol-water mixture in recalculation on the pseudobinary mixture were selected for research: the first point - 95/5 % wt. %; the second point - 5/95 % wt. %; the third azeotrope point - 88/12 % wt. %. For the selected points model mixtures were prepared to which 13 % wt. % of the extractive agent was added

Abstract:
The effect of deep eutectic solvents (DES), a mixture of glycerol with triethanolamine, urea and glucose, on the relative volatility of the components of an aqueous ethanol solution was investigated. Based on the open evaporation method, experimental studies of the vapor-liquid phase equilibrium conditions of the ethanol-water system with the addition of DES were carried out. The behavior of the residual concentration lines shows that the addition of DES increases the relative volatility of ethanol, which leads to its faster depletion in the cube.

Abstract:
Wastes have been considered to be a serious worldwide environmental problem in recent years. Because of increasing pollution, these wastes should be treated. However, industrial wastes can contain a number of valuable organic components. Recovery of these components is important economically. Using conventional distillation techniques, the separation of acetic acid and water is both impractical and uneconomical, because it often requires large number of trays and a high reflux ratio. In practice special techniques are used depending on the concentration of acetic acid. Between 30 and 70% (w/w)

При концентрації розчинів що регенерують 96,0-97,5% (мас.) застосовується десорбція при тиску, близькому до атмосферного. Прагнення отримати більш концентровані розчини призвело до необхідності впровадження вакуумної регенерації або до подачі в систему десорбції нейтрального агента - природного газу, що знижує парціальний тиск водяної пари і забезпечує отримання регенерованих поглиначів концентрацією 98,0-99,95% (мас.).
