AB  - In order to reduce negative influence of fossil fuels on environment, use of various renewable resources is highly promoted. Terpenes, naturally occurring in plants, can be added to petroleum fuel as its substitute up to a certain share. Thermodynamic properties of a fuel under high pressure and moderate temperature conditions are of significant importance for engine efficiency. This work reports density measurements of pure p-cymene, α-pinene, limonene and citral at temperatures (293.15–413.15) K and pressures (0.1–60) MPa, applying an Anton Paar DMA HP measuring cell. Density data were fitted by modified Tammann-Tait equation where the absolute average percentage deviation between measured and calculated densities was about 0.010%. The obtained parameters were used to estimate the isothermal compressibility, the isobaric thermal expansion coefficient, the internal pressure, and the difference between specific heat capacity at constant pressure and at constant volume. For examined compounds, all thermodynamic properties, except the internal pressure, decrease with pressure rise along an isotherm and increase as temperature increases at a constant pressure. The intersection point of isotherms for the isobaric thermal expansion coefficient for pure citral was registered at pressure 47 MPa, while for other analyzed terpenes the intersection point is above 60 MPa, outside the measurements pressure range.

AB  - Thermodynamic properties (density, viscosity, refractive index and speed of sound) of pure substances cis-3-hexen-1-ol, 1-hexanol and n-hexane and their binary systems cis-3-hexen-1-ol + n-hexane and 1-hexanol + n-hexane were measured. All measurements are reported in the range (288.15 to 318.15) K at seven temperatures and at atmospheric pressure. Excess molar volume (VE), viscosity deviation (Δη), refractive index deviation (ΔnD) and speed of sound deviation (Δu) were calculated based on the experimental data. Derivate properties were fitted using Redlich-Kister equation. Additionally, for analyzing the molecular interaction, the FT-IR spectroscopy and quantum chemical calculations were performed. The results show differences in viscosity deviation between cis-3-hexen-1-ol + n-hexane and 1-hexanol + n-hexane mixtures, indicating some specific role of double bonds in properties of the mixtures. The FT-IR spectra indicate change in double bond frequency between pure cis-3-hexen-1-ol and mixture of cis-3-hexen-1-ol + n-hexane, and quantum chemical calculations confirmed the possibility of double bond influence on the properties of the mixtures.

AB  - Experimental and theoretical methods were used to study two mixtures, 1-hexanol with nhexane and cis-3-hexen-1-ol with n-hexane. The experimental technics were used to determine excess molar volume and viscosity deviations in the temperature range from 288.15K to 318.15K. The data of excess molar volume indicate similar behavior of the two alcohols, 1-hexanol and cis-3-hexen-1-ol in mixtures with n-hexane. The experimental data are in accordance with molecular dynamics simulation of these mixtures, showing similar number of hydrogen bonds in the two mixtures. The experimental data of viscosity deviations show difference of the two mixtures, where the deviation is significantly larger for cis-3- hexen-1-ol and n-hexane mixture, indicating stronger interactions within cis-3-hexen-1-ol and n-hexane binary mixture. These experimental data are in accordance with quantum chemical calculations on interactions energies. Namely, calculated interaction energies show that interaction between single and double bonds are stronger, than interactions between two single bonds.
AB  - Eksperimentalne i teorijske metode korišćene su za proučavanje dve smeše, 1-heksanola sa n-heksanom i cis-3-heksen-1-ola sa n-heksanom. Eksperimentalne tehnike su korišćene za određivanje dopunskih zapremina i promene viskoznosti za temperaturni opseg od 288.15K do 318.15K. Podaci o dopunskoj molarnoj zapremini ukazuje na slično ponašanje dva alkohola, 1-heksanola i cis-3-heksen-1-ola u smešama sa n-heksanom. Eksperimentalni podaci su u skladu sa simulacijom molekularne dinamike ovih smeša, pokazujući sličan broj vodoničnih veza u dve smeše. Eksperimentalni podaci o promeni viskoznosti pokazuju značajnu razliku između dve smeše, odstupanje je značajno veće za smešu cis-3-heksen-1- ol i n-heksan, što ukazuje na jaču interakciju u binarnoj smeši cis-3-heksen-1-ola i nheksana. Ovi eksperimentalni podaci su u skladu sa kvantno-hemijskim proračunima energija interakcija na molekulskom nivou. Naime, izračunate energije interakcije pokazuju da je interakcija između jednostrukih i dvostrukih veza jača, nego interakcija između dve jednostruke veze.

AB  - SAFT equations of state have been widely used for the determination of different thermo-physical and phase equilibria properties. In order to use these equations as predictive models it is necessary to calculate the model parameters. In this work CK-SAFT and PC-SAFT equations of state were applied for the correlation of pure compounds densities in the wide ranges of temperature and pressure (288.15-413.15 K and 0.1-60 MPa, respectively). The calculations of densities for n-hexane, n-heptane, n-octane, toluene, dichloromethane and ethanol, under high pressure conditions, were performed with the new sets of parameters determined in this paper by CK-SAFT and PC-SAFT. Very good agreement between experimental and calculated density values was achieved, having absolute average percentage deviations lower than 0.5 %.

AB  - Continuous catalytic reforming (CCR) is known to convert refinery naphtha to a high-octane liquid product, also known as the reformate. In this paper, a First Principle Reaction Section Model for a CCR process is presented. Even though CCR is a well-established technology, the application of advanced, real-time optimization techniques that are able to quickly respond to any imposed changes onto the process, are necessary in the refinery business. This becomes particularly important as a result of changes in profit margin, changes in operating cost, and the introduction of new environmental legislations. Hence, we present a kinetic model for the CCR process using the so-called "lumped" concept. The reactors have been modeled using a quasi-steady-state approach. The unknown model parameters have been estimated by bench marking the First Principle Reaction Section results with a commercial CCR process owned by the Hungarian Oil and Gas Public Limited Company (INA-MOL). The proposed model has been tested and compared to data obtained from an existing CCR plant. The predictions of the model were found to be in good agreement with the experimental data. The relative absolute errors between the measured and model estimated variables have been found to be lower than 2%. The relative absolute error associated with the required fired heater duties were less than 1.0%. Simulating the reaction section of the CCR process requires less than 0.1 s of CPU time, which clearly indicates that this model can be very suitable for performing optimization studies. Moreover, this study shows that, although there is fluctuation in the composition of feedstock, the lumped kinetic approach was capable to predict the behavior of the CCR process well.

AB  - Continuous catalytic reforming (CCR) is known to convert refinery naphtha to a high-octane liquid product, also known as the reformate. In this paper, a First Principle Reaction Section Model for a CCR process is presented. Even though CCR is a well-established technology, the application of advanced, real-time optimization techniques that are able to quickly respond to any imposed changes onto the process, are necessary in the refinery business. This becomes particularly important as a result of changes in profit margin, changes in operating cost, and the introduction of new environmental legislations. Hence, we present a kinetic model for the CCR process using the so-called "lumped" concept. The reactors have been modeled using a quasi-steady-state approach. The unknown model parameters have been estimated by bench marking the First Principle Reaction Section results with a commercial CCR process owned by the Hungarian Oil and Gas Public Limited Company (INA-MOL). The proposed model has been tested and compared to data obtained from an existing CCR plant. The predictions of the model were found to be in good agreement with the experimental data. The relative absolute errors between the measured and model estimated variables have been found to be lower than 2%. The relative absolute error associated with the required fired heater duties were less than 1.0%. Simulating the reaction section of the CCR process requires less than 0.1 s of CPU time, which clearly indicates that this model can be very suitable for performing optimization studies. Moreover, this study shows that, although there is fluctuation in the composition of feedstock, the lumped kinetic approach was capable to predict the behavior of the CCR process well.

AB  - In order to reduce the usage of fossil fuels in industrial sectors by meeting the requirements of production processes, new heat integration and heat recovery approaches are developed. The goal of this study is to develop an approach to increase energy efficiency of an industrial zone by recovering and reusing waste heat via indirect heat integration. Industrial zones usually consist of multiple independent plants, where each plant is supplied by an independent utility system, as a decentralized system. In this study, a new approach is developed to target minimum energy requirements where an industrial zone would be supplied by a centralized utility system instead of decentralized utility system. The approach assumes that all process plants in an industrial zone are linked through the central utility system. This method is formulated as a linear programming problem (LP). Moreover, the proposed method may be used for decision making related to energy integration strategy of an industrial zone. In addition, the proposed method was applied on a case study. The results revealed that saving of fossil fuel could be achieved.

The calculated interaction energies are compared with accurate CCSD(T)/CBS energies. The data show that most levels of theory have the highest errors for systems with butane dimers, and calculated interaction energies in these systems are overestimated. The best levels, overall for all systems, are BLYP-D3BJ/clef2-QZVP and BLYP-D3BJ/cc-pVQZ with similar root mean square deviation (RMSD) values of 0.056 kcal mo1-1 and 0.060 kcalmorl compared to CCSD(T) values. The best level for (1) 2-butene dimers is B3LYP-D3BJ/aug-cc-pVDZ; for (2) interactions between 2-butene and butane is BLYP-D3BJ/def2-SVP; while for (3) butane dimers is BLYP-D3BJ/def2-QZVP. The differences in calculated energies among several methods are not high, however, it is important that most of the DFT methods overestimate interactions in butane dimers.

AB  - The ability of non-toxic and biodegradable deep eutectic solvent (DES) choline chloride + DL-malic acid in mole ratio 1: 1, for the breaking of the azeotropes heptane + methanol and toluene + methanol by means of liquid-liquid extraction was evaluated. Ternary liquid-liquid equilibrium experiments were performed at 298.15 K and at atmospheric pressure. Densities, viscosities and refractive indices of DES + methanol and water + DES systems were experimentally determined over a wide temperature range and at atmospheric pressure. Additionally, the viscosities of DES + glycerol mixture were determined at temperatures up to 363.15 K to check how much the addition of glycerol decreases high viscosities of DES. The results indicate that the addition of small amounts of water or glycerol as a third component significantly decreases the viscosity of the investigated deep eutectic solvent. Based on the selectivity and distribution ratio values, the extraction ability of the investigated deep eutectic solvent, in comparison with the conventionally used solvents, yields promising results. Non-random two-liquid (NRTL) and universal quasichemical (UNIQUAC) models were satisfactorily applied for correlation of experimental phase equilibrium data for two ternary mixtures.

AB  - We propose a systematic model for the optimum design of Organic Rankine Cycles (ORC) used for power generation from multiple heat sources available at different temperatures. The model enables the automated generation of inclusive and flexible ORC cascades and is optimized using a global optimization algorithm. Design parameters include the number of ORC cascades, the shared structure of the heat exchanger network, the operating conditions and the working fluid used in each cascade in order to identify an overall ORC structure that maximizes the power output. Results indicate significant operating improvements from using a double ORC cascade with different working fluids.

AB  - This work presents a systematic approach toward the design of Organic Rankine Cycles (ORC) for the generation of power from multiple heat sources available at different temperature levels. The design problem is approached in a mixed-integer non-linear programming (MINLP) formulation where an inclusive and flexible ORC model is automatically evolved by a deterministic algorithm for global optimization. The basic building block of the model is the ORC cascade which consists of a heat extraction, a power generation, a condensation and a liquid pressurization section. The aim of the optimization is to determine the optimum number of ORC cascades, the structure of the heat exchanger network shared among different cascades, the operating conditions and the working fluid used in each cascade in order to identify an overall ORC structure that maximizes the power output. The approach is illustrated through a case study which indicates that a system of two waste heat sources is best exploited through two interconnected ORC utilizing different working fluids.

AB  - Noncovalent interactions of cis- and trans-2-butene, as the smallest model systems of molecules with cis and trans double bonds, were studied to find potential differences in interactions of these molecules. The study was performed using quantum chemical methods including very accurate CCSD(T)/CBS method. We studied parallel and displaced parallel interactions in 2-butene dimers, in butane dimers, and between 2-butene and saturated butane. The results show the trend that interactions of 2-butene with butane are the strongest, followed by interactions in butane dimers, whereas the interaction in 2-butene dimers are the weakest. The strongest calculated interaction energy is between trans-2-butene and butane, with a CCSD(T)/CBS energy of -2.80kcalmol(-1). Interactions in cis-2-butene dimers are stronger than interactions in trans-2-butene dimers. Interestingly, some of the interactions involving 2-butene are as strong as interactions in a benzene dimer. These insights into interactions of cis- and trans-2-butene can improve understanding of the properties and processes that involve molecules with cis and trans double bonds, such as fatty acids and polymers.

AB  - Environmental regulations imposed on transport fuels, especially specifications on sulfur and nitrogen content, generally boost hydrogen requirements in refining industries. The catalytic naphtha reformer (CNR) process is one of the major sources of hydrogen in naphtha refinery, thus improving its hydrogen production would be of great importance for refining industries. Close examination of the reaction kinetics of CNR processes has identified temperature, hydrogen concentration and catalyst activity as key variables affecting the process's performance. In this paper, a new reactor concept is developed that better exploits these process variables. The proposed membrane moving-bed reactor promises to significantly outperform the conventional continuous catalyst regenerative (CCR) design. A case study identifies improvements of 23.6 mol% in hydrogen production, 18.8 mol% in aromatics production. Moreover, the reformate yield was found to increase by 10.6 wt%, while the production of light gases decreases to a value of 18.6 wt%. Copyright

abstract = "Environmental regulations imposed on transport fuels, especially specifications on sulfur and nitrogen content, generally boost hydrogen requirements in refining industries. The catalytic naphtha reformer (CNR) process is one of the major sources of hydrogen in naphtha refinery, thus improving its hydrogen production would be of great importance for refining industries. Close examination of the reaction kinetics of CNR processes has identified temperature, hydrogen concentration and catalyst activity as key variables affecting the process's performance. In this paper, a new reactor concept is developed that better exploits these process variables. The proposed membrane moving-bed reactor promises to significantly outperform the conventional continuous catalyst regenerative (CCR) design. A case study identifies improvements of 23.6 mol% in hydrogen production, 18.8 mol% in aromatics production. Moreover, the reformate yield was found to increase by 10.6 wt%, while the production of light gases decreases to a value of 18.6 wt%. Copyright",
