This paper summarizes the round-table discussion that was held during the European Congress of Chemical Engineering (ECCE) in Nice, France, in October 2015 on this topic. The panellists come from different fields of chemical engineering and have thus brought in different perspectives. The objective was to determine paths for developing innovative approaches in view of process optimization. The terminology is a first obstacle that was clarified. Energy efficiency can be envisaged either by optimizing thermodynamic functions (entropy or exergy), more pragmatically by selecting the adequate unit operation or in a very general vision by considering all decision variables (i.e. including economic and political) that may have an impact on the final service provided to society. The second issue relates to improving collaboration among various actors. These may be defined in terms of type of responsibility (industrials, mostly market-driven, or academic), or in terms of discipline. The role of professional societies as the European Federation for Chemical Engineers (EFCE) is stressed as a promotor of collaboration between disciplines. Finally, once willingness for collaboration is identified, the final question is how it can lead to true innovation. The largest innovation potential is often found at the interface between fields. Yet, it often requires both an effort to explain the mutual challenges in a didactic manner, and the development of tools that make it possible to each partner to be efficient in his own field while being aware of the global goal and of the constraints of the others. © 2017 Institution of Chemical Engineers

In this work, experimental vapor-liquid equilibria (VLE) of water + ethanol + five aroma compound (two monoterpene hydrocarbons, α-pinene and d-limonene, and three oxygenated compounds, linalool, citral, and linalool oxide) mixtures were measured at boiling point at 101.3 kPa for ethanol molar fractions ranging from 0.0140 to 0.8389. The five aroma compounds were selected for their strong contribution to the aroma of the distillate of bitter orange essential oil. First, the thermodynamic consistency of the experimental VLE data was validated. Then the NRTL and Henry's law type models were tested to correlate the experimental data. Good agreement was obtained with both models to predict the phase equilibrium of the oxygenated compounds, and a better agreement was obtained with Henry's law type models for the monoterpene hydrocarbons in this kind of mixture. © 2012 American Chemical Society.

Demixing phenomena in liquid ternary systems are widely used in chemical engineering processes. When a critical point is observed, the composition of this invariant point of major interest is experimentally difficult to determine. A simple calculation method for the critical point is proposed using the experimental tie-lines. The computing treatment is based on the application of the barycentric weighting of the binodal points in order to extend the rectilinear diameter method and the exploitation of the modulus of the experimental tie-lines. A systematic study was carried out on a large set of ternary systems taken from DECHEMA and NIST. The results are compared with those available in literature or calculated by standard methods using binary interaction parameters. Very good agreements are obtained when the experimental tie-lines are located close to the critical point. The method can be extended to wide miscibility gaps by using a polynomial deviation instead of the rectilinear diameter line. A typical case is detailed (2-butanone. +. 2-butanol. +. water at various temperatures). The results lead to (i) the point by point calculation of the entire binodal curve and (ii) the thermal evolution of the critical point and the possible disappearance of the critical point when temperature increases. © 2014 The Institution of Chemical Engineers.

The chemical product substitution process is undertaken by chemical industries for complying with regulations, like REACH in Europe. Initially devoted to chemists, chemicals substitution is nowadays a complex process involving corporate, business and engineering stakeholders across the chemical enterprise for orienting the search toward a sustainable solution. We formalize a decision making process framework dedicated to the sustainable chemical product design activity in an industrial context. The framework aims at improving the sharing of information and knowledge and at enabling a collaborative work across the chemical enterprise stakeholders at the strategic, tactical and operational levels. It is supported by information and communication technologies (ICT) and integrates a computer aided molecular design tool. During the initial intelligence phase, a systemic analysis of the needs and usages enables to define the product requirements. In the design phase, they are compiled with the help of a facilitator to generate the input file of a computer aided product design tool. This multiobjective tool is designed to find mixtures with molecular fragments issued from renewable raw materials, and is able to handle environment-health and safety related properties along with process physicochemical properties. The final choice phase discusses the solution relevancy and provides feedback, before launching the product manufacturing. The framework is illustrated by the search of a bio-sourced water-solvent mixture formulation for lithographic blanket wash used in printing industry. The sustainability of the solution is assessed by using the sustainability shades method. © 2014 Elsevier B.V. All rights reserved.

On industrial sites, the promotion of best practices to enable an efficient utilization of energy has emerged as one of the major point of focus. Among the different approaches existing to improve industrial processes, the exergy analysis, although limited to the academic world, has been shown to be a powerful tool for improving energy efficiency of thermal and chemical systems. The purpose of this paper is then to present the use of the ProSimPlus® modelling and simulation environment as an exergy analysis computer-aided tool. Expressions implemented in the simulator for computing exergies in its various forms are presented. The adopted approach for calculating exergy efficiency in a systematic way is also exposed; it combines the fuel-product concepts to the transit exergy concept. ProsimPlus® exergy module's capabilities are illustrated through the example of an ammonia production plant. © 2015 Elsevier Ltd.

This paper presents a general methodology for exergy balance in chemical and thermal processes integrated in ProSimPlus ® as a well-adapted process simulator for energy efficiency analysis. In this work, as well as using the general expressions for heat and work streams, the whole exergy balance is presented within only one software in order to fully automate exergy analysis. In addition, after exergy balance, the essential elements such as source of irreversibility for exergy analysis are presented to help the user for modifications on either process or utility system. The applicability of the proposed methodology in ProSimPlus ® is shown through a simple scheme of Natural Gas Liquids (NGL) recovery process and its steam utility system. The methodology does not only provide the user with necessary exergetic criteria to pinpoint the source of exergy losses, it also helps the user to find the way to reduce the exergy losses. These features of the proposed exergy calculator make it preferable for its implementation in ProSimPlus ® to define the most realistic and profitable retrofit projects on the existing chemical and thermal plants. © 2012 Elsevier Ltd.

It is crucial to know the solubility of gaseous and liquid hydrocarbons in aqueous alkanolamine solutions in order to quantify accurately the hydrocarbon losses in treating processes. Hence, consistent experimental data and accurate models are essential for the efficient design and optimization of these processes. In this work, a homogeneous approach based on the modified Volume Translation Peng-Robinson (VTPR) cubic equation of state was adopted to represent the solubility of methane, ethane and propane in aqueous mono-ethanol-amine, di-ethanol-amine and methyl-di-ethanol-amine which are the most common solvents used in the effluent treatment processes. The model parameters were estimated on the basis of binary and ternary vapor-liquid and liquid-liquid equilibrium data. The model developed shows a satisfactory representation of the experimental data with average deviations ranging from 1 to 28% for all systems, and gives a solid foundation for predicting hydrocarbon solubility in aqueous alkanolamine solutions. © 2016 Elsevier B.V.

Pinch analysis [1] is a well-known methodology, commonly used in the industry to optimize process energy consumption. Specific developments have been done in a commercially-available process simulator, ProSimPlus® Energy [2] to help process engineers in their daily work. Composite curves, characteristics of cold and hot streams of the process are automatically generated and an appropriate heat exchanger network is proposed by the software, depending on several constraints provided by the user. Energy management specific unit operations (heat pumps, ORC, boilers⋯) were also added in the library of the software to help the user to quickly analyze the impact on energy efficiency for this equipment. To tackle the challenge of process energy management enhancement, exergy analysis has been shown by Kotas [3] to also be a useful tool that exploits the concept of energy quality to quantify the portion of energy that can be practically recovered. Unfortunately, in contrast to enthalpy, this concept is less familiar to chemical engineers and can be rather difficult to handle. In particular, this physical quantity is rarely implemented in process simulators. To make exergy analysis more understandable and to demonstrate its value for the analysis of the energy efficiency of a process and its utilities, a fully-automated exergy analysis tool has been developed and integrated in ProSimPlus® Energy [3], [4]. The software combines these approaches, allowing the user to propose the most efficient process taking into account all of the defined constraints.

In many cases of miscibility gap in ternary systems, one critical point at least, stable or metastable, can be observed under isobaric and isothermal conditions. The experimental determination of this invariant point is difficult but its knowledge is essential. The authors propose a method for calculating the composition of the invariant solution starting from the composition of the liquid phases in equilibrium. The computing method is based on the barycentric properties of the conjugate solutions (binodal points) and an extension of the straight diameter method. A systematic study was carried out on a large number of ternary systems involving diverse constituents (230 sets ternary systems at various temperatures). Thus the results are presented and analyzed by means of consistency tests. © Owned by the authors, published by EDP Sciences, 2013.
