We further elaborate on the generalized formulation for cubic equation of state proposed by Cismondi and Mollerup [Fluid Phase Equilib. 232, 74–89 (2005)]. With this formulation, all well-known equations can be described with a certain pair values, which allow generic implementation different state. Based we derive complete thermodynamic model computational fluid dynamics simulations providing ...

O uso softwares como Microsoft Excel ou LibreOffice Calc para ensinar e exemplificar exercícios envolvendo modelos termodinâmicos é de fácil implementação em sala aula. Dessa forma, o objetivo do presente estudo foi avaliar a densidade dióxido carbono (CO2) estado supercrítico através 4 equações distintas (Peng-Robinson, Redlich–Kwong, Soave Redlich–Kwong van der Waals) dos parâmetros temperatu...

The supercritical extraction process is a technique that has increasingly been applied in various industries recent years. Solubility determination the region key feature for this process. However, high expenses and time consuming experiments task obligates need modeling. In study, thermodynamic model proposed to correlate solubility of solid hydrocarbons, namely, 1-hexadecanol, 1-octadecanol, ...

The nanomolar kinase inhibitory activity of staurosporine (1) and K252a (5) has prompted a continuing effort to isolate and/or synthesize novel pyranosylated and furanosylated indolocarbazoles.l,2,3. 4 Recently, we reported the enantioselective synthesis of (+)-K252a via an approach involving the late-stage coupling of aglycon 8 and furanose 9 (Scheme 1). Although this approach proved efficient...

Obstructive nephropathy constitutes a major cause of pediatric renal progressive disease. The mechanisms leading to disease progression are still poorly understood. Kidney fibrotic lesions are reproduced using a model of partial unilateral ureteral obstruction (pUUO) in newborn mice. Based on data showing significant mast cell (MC) infiltration in patients, we investigated the role of MC and mu...

Maintenance experts involved in managing major maintenance activities such as; Major overhauls, outages, shutdowns and turnarounds (MoOSTs) are constantly faced with uncertainties during the planning and/or execution phases, which often stretches beyond organisation’s standard operating procedures require intervention of staff expertise. This underpins a need to complement sustain existing effo...

Galaxy mergers are known to trigger both extended and central star formation. However, what remains be understood is whether this triggered formation facilitated by enhanced efficiencies, or an abundance of molecular gas fuel. This work presents spatially resolved measurements CO emission collected with the Atacama Large Millimetre Array (ALMA) for 20 merging galaxies (either pairs post-mergers...

In the present paper, Mathematica, the famous computer algebra, is used to perform steadystate and dynamic simulations of a multi-component distillation column. In order to describe the vapor liquid equilibrium (VLE) relationships and to compute the vaporand liquid-phase enthalpies, the Soave Redlich Kwong equation of state (SRK EOS) is chosen. Rigorous modeling is performed where both mass and...

In the present work, we develop a predictive corresponding-states correlation for the binary interaction parameters of systems composed of hydrocarbons (HC), up to C10, with CO2 and H2S. Experimental data were collected from the literature for 12 HC/CO2 systems (1017 data points for 90 isotherms), 7 HC/H2S systems (293 data points for 27 isotherms), and the CO2/H2S systems (61 data points for 1...
