“…Dynamic viscosities of smoke (gas) gaseous components were calculated at 37 • C. Knowing the dynamic viscosities of smoke (gas) components, dynamic viscosity of the smoke (gas) mixture was calculated [19][20][21][22]. The diameter of particulate matter that was removed at 50% efficiency (d 50 ) from 37 • C smoke (gas) was established.…”

Cyclones are widely used for separating particles from gas in energy production objects. The efficiency of conventional centrifugal air cleaning devices ranges from 85 to 90%, but the weakness of many cyclones is the low collection efficiency of particles less than 10 μm in diameter. The novelty of this work is the research of the channel-type treatment device, with few levels adapted for precipitation of fine particulate matter, acting by a centrifugal and filtration principle. Many factors have an impact on cyclone efficiency—humidity, temperature, gas (air) composition, airflow velocity and etc. Many scientists evaluated only the effect of origin and size of PM on cyclone efficiency. The effect of gas (air) composition and temperature, and humidity on the multi-channel cyclone-separator efficiency still demands contributions. Complex theoretical and experimental research on air flow parameters and the efficiency of a cylindrical eight-channel system with adjustable half-rings for removing fine-dispersive particles (<20 μm) was carried out. The impact of air humidity and temperature on air flow, and gaseous smoke components on the removal of wood ashes was analyzed. The dusty gas flow was regulated. During the experiment, the average velocity of the cyclone was 16 m/s, and the temperature was 20–50 °C. The current paper presents experimental research results of wood ash removal in an eight-channel cyclone and theoretical methodology for the calculation of airflow parameters and cyclone effectiveness.

“…describes solute transfer into a condensed phase from the gas phase. Specific properties that have been successfully described include partition coefficients [20][21][22], molar solubility ratios [19,23,24], aquatic toxicities [25][26][27], nasal pungencies [28], gas-liquid chromatographic and HPLC retention data [18,[29][30][31][32][33], Draize scores and eye irritation thresholds [34,35], human and rat intestinal adsorption data [36,37], human skin permeability [38,39], infinite dilution activity coefficients [40,41], molar enthalpies of solvation [42][43][44], standard molar vaporization [45] and sublimation [46] at 298 K, vapor pressures [47], and limiting diffusion coefficients [48,49]. Unlike many of the QSPRs that have been proposed in the published chemical and engineering literature, Equations ( 1) and ( 2) are based upon a fundamental understanding of how molecules interact in solution.…”

Abraham model L solute descriptors have been determined for 149 additional C11 to C42 monomethylated and polymethylated alkanes based on published Kovat’s retention indices based upon gas–liquid chromatographic measurements. The calculated solute descriptors, in combination with previously published Abraham model correlations, can be used to predict a number of very important chemical and thermodynamic properties including partition coefficients, molar solubility ratios, gas–liquid chromatographic and HPLC retention data, infinite dilution activity coefficients, molar enthalpies of solvation, standard molar vaporization and sublimation at 298 K, vapor pressures, and limiting diffusion coefficients. The predictive computations are illustrated by estimating both the standard molar enthalpies of sublimation and the enthalpies of solvation in benzene for the monomethylated and polymethylated alkanes considered in the current study.
