To separate the azeotropic system of 2-methyl-2-butanol and water, liquid–liquid equilibria (LLE) data water + solvents (anisole, isoamyl alcohol, 1-octanol, ethyl acetate, methyl isobutyl ketone) were obtained at 308.2 K under 101.3 kPa, all systems are Treybal's type II. The distribution coefficient selectivity used to evaluate effect extraction separation 2-methyl-2-butanol. Meanwhile, quantum chemical methods analyze intermolecular interactions. Finally, Non-random Two Liquids UNIQUAC...
In the process of CO2 catalytic hydrogenation to methanol, saturated alkanes will be produced, and purity refined methanol reduced. Therefore, separation from is very important. The was studied in this work. suitable solvent screened by σ-profile analysis, interaction energy extraction performance analysis. Finally, ethylene glycol selected as for alkanes. liquid–liquid equilibrium (LLE) data {n-hexane, n-heptane, iso-octane, n-nonane} + were measured at 303.2 K 101.3 kPa, respectively....
The development and research of biomass fuels have been paid more attention. production methacrylic acid is accompanied by a large amount water environmental pollution. Therefore, the separation from aqueous solution great significance for industrial protection. liquid–liquid equilibrium (LLE) ternary systems + alcohol solvents at 303.2 K 101.3 kPa was investigated. Thermodynamic models (NRTL UNIQUAC) were used to correlate regress experimental data. root-mean-square deviation (RMSD %)...
Water is produced during the industrial production of 3-mercaptopropionic acid; so to separate and purify acid, four common solvents {n-octanol, isopropyl acetate, methyl ketone, diisopropyl ether} were chosen water acid. The liquid–liquid equilibrium (LLE) data +3-mercaptopropionic acid + measured at 303.2 K 101.3 kPa. distribution coefficient (D) separation factor (S) calculated compare extraction performance solvents. Next, NRTL UNIQUAC models used regress experimental relevant regression...
In this work, the liquid–liquid equilibrium (LLE) data of ternary mixtures water + o-cresol solvents (mesityl oxide or n-propyl acetate) were measured at 303.2, 313.2, and 323.2 K under 101.3 kPa. The distribution coefficients (D) separation factors (S) used to evaluate effect extracting from water, high D S values indicated that two are promising. At same time, NRTL UNIQUAC models correlate experimental obtain regression parameters with root-mean-square (RMSD) less than 0.50%. addition,...
Water lubricated bearings can be used to reduce contamination due lubricant leakage in heavy machinery such as power positioning systems of offshore platforms and ship propulsion systems. The lubrication model a textured two-dimensional parallel friction pair water-lubricated journal bearing are developed investigate the performance. governing equation is solved, fluid cavitation analyzed using Zwart-Gerber-Belamri (ZGB) model. A multi-objective optimization method combining response surface...
Misalignment effects increase the risk of scratch or seizure failure for journal bearings-rotor system. To investigate performances misaligned bearings, a full-scale system test rig is designed and orbits are tested under different speeds. Then, THD lubrication model established to simulate misalignment conditions. The results show that system, center bearing closing coupling fixed around coupling. far away floating gradually with an increasing speed. vibration amplitude larger than from...
The transient hydrodynamic lubrication model of tilting pad journal bearings (TPJBs) was established by the computational fluid dynamics (CFD) method and self-developed dynamic grid program. fluid-structure interaction between flow field rotor motion, pads rotations realized. feasibility is proved comparing with experimental data. response TPJBs under various unbalance, loading modes rotating speeds studied. further analyzed through a research relationships among shaft whirl orbits, force...
Summary Inhomogeneity is a common characteristic of the underground media. In order to study propagation characteristics waves in continuous media, The elastic wave equation heterogeneous media established based on basic earth mechanics. parameters are spatially variable. Then, according acoustic approximation, scalar expressed by displacement established, and frequency-wavenumber domain operator decoupling solution method. Thus, we get describing P-wave medium. accuracy this method proved...
Summary Elastic reverse-time migration (RTM) has shown significant advantages in obtaining depth-domain multi-wave imaging results, but also remains a considerable challenge its practical application partly owing to the complexities of multi-mode elastic wavefields heterogeneous medium. We present decoupled P- and S-waves propagator form an efficient RTM framework, without assumption homogeneous Lame´ parameters. Also, there is no mode conversion occurs using proposed even case shear modulus...
