“…Step 1, the initial HEN model synthesis was performed, as described in Nemet et al (2017), using estimated area density factors for volume, mass and, consequently, for risk indicator assessment. After obtaining an initial HEN, each heat exchanger was optimized separately, based on the selected type of heat exchanger.…”

The 2 nd International Conference on Technologies & Business Models for Circular Economy (TBMCE) was devoted to presentations of circular economy concepts, technologies and methodologies that contribute to the shift of business entities and society as a whole to a more responsible, circular management of resources. In the framework of TBMCE 2019, we presented the Strategic Research and Innovative Partnership -Network for the Transition to Circular Economy (SRIP-CE) as a platform for establishing a successful long-term public-private partnership. The conference program included panel discussions, plenary and keynote sessions, oral and poster presentations on the following topics: Sustainable energy, Biomass and alternative raw materials, Circular business models, Secondary raw materials and functional materials, ICT in Circular Economy, Processes and technologies. TBMCE 2019 was organized by Faculty of Chemistry and Chemical Engineering, University of Maribor and held in Portorož, Slovenia at the Grand Hotel Bernardin from October 24th to October 25th, 2019. The event was under the patronage of Ministry of Economic Development and Technology.

“…Inchaurregui-Méndez et al and Vazquez-Román et al proposed MINLP models to optimize the layout of facilities with potential toxic release fluids, which included the location of heat exchangers. Nemet et al presented a superstructure approach for the synthesis of HENs while simultaneously considering risk assessment. Their superstructure included the selection of direct or indirect heat transfer, different types of heat exchangers, and limiting values for risk in certain types of individual exchangers.…”

Usually, heat exchanger network (HEN) problems focus on the design of networks that achieve full energy integration. In this work, we analyze the HEN design problem by considering fully integrated HENs (which achieve the target of minimum utility consumption) and partially integrated alternatives. Within this context, economic, environmental, and safety indicators are analyzed to detect which design alternative is the most suitable one. The framework is applied for the design of an HEN of an industrial process to produce ethylene and propylene using natural gas as feedstock. It is shown how a partially integrated network outperforms the one with minimum energy consumption for some of the metrics considered in this work. It is shown how a fully integrated network does not provide a significant improvement from economic and environmental aspects. Furthermore, the safety indicator shows that there is a point after which if more heat exchangers are added, then the HEN becomes more hazardous.
