“…Only steam production by a gas turbine and a dual-fuel furnace was considered here for the sake of illustration. The proposed methodology can be extended to other kinds of processes in order to improve the energy efficiency of conventional technologies (for instance, for multiple-effect evaporators (Madoumier et al 2013)) and to shift from the current fossil fuel-dominant energy supply mode to one with a higher proportion of renewable energy, thus implementing the transition from fossil fuel-based energy systems to renewable energy-based ones. The proposed approach is then particularly useful for embedding process simulation and LCA in an external multiobjective optimization loop: by combining LCA with multiobjective optimization (Yue et al 2016), the environmental impacts for a given product could be simultaneously optimized with economic assessment, using Life Cycle Cost Assessment so that both ecologically and economically sounder decisions can be made.…”

“…For the sake of illustration, the steam requirement of the chemical process serves as a test case, in which benzene production by the hydrodealkylation of toluene (HDA) process (Douglas 1998) and the gas turbine model in Ariane are considered. The work carried out in (Ouattara et al 2013) indicates that the HDA process requires an average of 50 t/h steam (distillation columns, furnace and flashes included) at pressures of 40 and 10 bar. The gas turbine is used for the steam production with natural gas as a fuel and a pressure of 40 bars.…”

Life Cycle Assessment (LCA) is now a mature environmental management strategy that is internationally standardized. A cornerstone of LCA involves Life Cycle Inventory (LCI) databases, which are largely implemented in several types of research. Finding consistent and transparent LCI data for LCAs still remains difficult. Setting up inventory data can be one of the most labour-and timeintensive stages of LCA. It is often challenging due to the lack of appropriate data for the product system under study (e.g. for production of chemicals). With the aim of bridging this gap, this paper proposes the combined use of a process simulation tool, experimental process data and LCA for the computation of energy-related emissions in connection with a given process. The case studies address the environmental impact assessment associated with steam production from a gas turbine. The practical application of the methodological framework is that different operating conditions and technologies can be modelled and evaluated systematically by an energy production simulator, in order to mitigate the effect of lack of data on environmental impact assessments. The combination of LCA and process modelling enables various alternatives for the energy production process to be assessed and can thus be used as a support for decision-making in a system-based approach.

Nowadays, eco‐designing products is increasingly practiced. The next challenge for sustainability is to optimize production processes. Biorefineries are particularly concerned with this improvement, because they use renewable resources. To identify the contribution of transformation processes to the overall environmental impacts, Life Cycle Assessment (LCA) appears as the adequate method. A literature review highlights that LCA is mainly performed on biorefineries to compare biomass feedstocks between them and to a fossil reference. Another part of environmental LCA compares the impacts of different processing routes. Nevertheless, these evaluations concern already designed processes. Generally, processes are considered as a unique operation in assessments. However, some criteria like operating can notably modify environmental burdens. The eco‐design of biorefinery processes can be guided by coupling process simulation to LCA. This method has been emerging in the chemical sector in recent years. Consequently, this paper proposes a new methodological approach to assessing the complete sustainability of biorefinery processes, since its first design stages. In addition to coupling process simulation and environmental LCA, the other pillars of sustainability will be assessed. Indeed, Life Cycle Costing and Social Life Cycle Assessment can be performed to obtain an integrated methodological framework. The simultaneous optimization of the environmental, economic, and social performances of the process can lead to antagonist ways of improving. Consequently, compromises should be realized. Thereby, the multi‐objective optimization can be accomplished by a metaheuristic method supported by a decision‐making tool. Finally, the main limits of this method and some perspectives and ways for improving are discussed. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd

“…The former approach suffers yet from a lack of process models implemented in current LCA tools while the latter needs to broaden the scope of the studied system. Following these guidelines, a methodology which is intended to design eco‐efficient processes has been developed in and applied in , taking into account economic and environmental considerations to obtain an eco‐friendly and economically viable design. The methodology performed an environmental impact analysis considering not only the process but also its energy requirements by using process models implemented in the Ariane software tool developed by ProSim SA.…”

Because of the central position of the chemical industries along the value chain, process design has a pivotal role, involving many decision makers and multiple levels of decisions. To tackle the environmental concern at source, this article presents a methodological framework for process ecodesign, coupling flowsheeting simulators both for production and energy processes with a Life Cycle Assessment module that generalizes and automates the evaluation of environmental impacts. The life cycle inventory is carried out through the combined use of mass and energy balances resulting both from the global simulation of the process and its associated energy production requirement and from the use of inventory database (i.e., Ecoinvent v3) embedded in the Life Cycle Assessment software tool used (SimaPro). Different process alternatives can thus be evaluated in a systematic way and the energy‐related emissions for any given process that match exactly the real situation can be computed without introducing a bias in the estimation. Through comparisons between a case base and process alternatives, a systematic decision can be made in terms of whether a solution is moving the process towards a more sustainable operation. The effectiveness of the proposed framework is first illustrated through the case study of benzene production and second, by a biodiesel production process from waste vegetable oils which is one of the foremost alternative fuels to those refined from petroleum products. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 777–796, 2018
