“…La simulation du procédé de production de MeOH ayant été réalisée, la première étape consiste à procéder au diagnostic exergétique du procédé. De récents travaux menés au Laboratoire de Génie Chimique ont contribué au développement du module Analyse Exergétique dans le simulateur de procédé ProSimPlus (Gourmelon et al, 2015). Grâce à ce module, il est possible de réaliser des bilans exergétiques de manière aussi aisée que les bilans enthalpiques.…”

Following the third part of the IPCC report (GIEC, 2022), carbon capture and utilisation of CO2 emitted by fossil fuel represents one of many ways to curb an increasingly alarming global warming. Reaching this goal implies the transition from a fossil fuel dependant and energy-intensive society to a sober and carbon-free one. According to the (ADEME et al., 2020), steam methane reforming, main production path for syngas, still generates 11 kg CO2/kg H2. Countless scientists have already studied different solutions aiming to lower these emissions, including through the design of innovative CO2 recovering processes. Among these solutions, the integration of CO2 within natural gas based methanol (MeOH) production processes appears to be promising (Nami et al., 2019 ; Wang et al., 2021). Contributing to the development of these more sober and sustainable production sectors involves the implementation of innovative conceptual approaches, along with the design of processes with excellent energetic performances. To this end, there has been a growing interest in exergy analysis in the last few years. This technique is able to identify and characterise a process’ thermodynamic inefficiencies, thus assisting the engineer in the development of innovative processes (Dincer and Rosen, 2015; Gourmelon et al., 2017). The COOPERE method (COmbiner Optimisation des ProcédEs, Récupération et analyse Exergétique), developed in the Laboratoire de Génie Chimique de Toulouse (Gourmelon, 2015), lies on the combined use of exergy analysis, a case based reasoning approach (Roldan Reyes, 2012) and pinch analysis. This method enables to design processes as energetically sober as economically viable. In this paper, the latter is applied to a MeOH production process based on natural gas and recovered CO2, described by (Yang et al., 2018).

“…Exergy balance of a system, from [6] Exergy is an optimization approach that can support and extend the conventional LCA. In fact, classical LCA approach focuses deeply on environmental emissions, while EA is much more centered on products, highlighting the availability of resources and system efficiency.…”

At present, the focus on manufacturing-sustainability is not necessarily on energy management, but rather on its intelligent use. An increase in productivity leads to a reduction in costs, but may increase consumptions based on demand elasticity as rebound effect. The article focuses on exergy coupled with Life Cycle Assessment to address manufacturing-sustainability. Indicators are widely adopted in order to better interpret and communicate the results of a hybrid analysis; they are easy to interpret and represent a useful strategy to quickly and intuitively detect changes in the energy efficiency and quality of processes that are subject to change in time. The aim of this work is to firstly provide an overview on the metrics related to the hybrid or coupled use of exergy and Life Cycle Assessment, their meaning, their practice in particular use cases. The most representative indicators are compared within a real case study and discussion of the results is provided. Among the main outcomes, their accuracy in evaluating environmental but especially on social and economic aspects is not yet clear. The lack of complete and up-to-date data and uncertainty analysis is often problematic, such as the lack of scientific consistency in the interpretation of the assessment.

“…Among the several process integration technics, one can find the thermodynamic approaches such as the Pinch Methodology and the Exergy Analysis. While the latter, almost limited to the academic world, can be applied to identify thermodynamic imperfections of a given process (Gourmelon et al, 2015c), Pinch Technology aims at improving heat-exchanger network of a process, solely dealing with heat transfers, excluding chemical or pressure changes. To overcome these limitations, it seems appropriate to implement a methodology combining Exergy Analysis and Pinch Technology.…”

This paper intends to present a novel approach, called PiXAR, combining Pinch technology and Exergy Analysis for the analysis and retrofit design of existing industrial processes. This methodology divided into three steps : modeling and simulation within a process simulation software, analysis of the process with a combined utilisation of pinch and exergy analysis, and finally the retrofit design of the process based upon a case-based reasoning system. The PiXAR methodology, which is intended to be pragmatic, is illustrated through two case-studies.
