“…Eco-industrial parks provide an opportunity for co-monetizing oxygen and hydrogen. While numerous approaches exist to design eco-industrial parks, the Carbon-Hydrogen-Oxygen Symbiosis Networks (CHOSYN) framework (Panu et al 2019;Noureldin and El-Halwagi 2015;Topolski et al 2018;El-Halwagi 2017b;Topolski et al 2019;Al-Fadhli et al 2019;Park et al 2020) provides an ideal framework for integrating hydrogen and oxygen into an EIP. For example, in a case where close to an existing industrial city, the approach proposed by Noureldin et al (Noureldin and El-Halwagi 2015) may be used to reduce the feedstock cost of the existing plants.…”

Power to gas (PtG) capitalizes on the free or low-cost power made available during frequent mismatches between power demand and power supply by converting water into hydrogen and oxygen via electrolysis. Current PtG projects vent the oxygen to the atmosphere and utilize the hydrogen for myriad purposes. Although oxygen has relatively little value when compared to hydrogen on a mass basis, the value of oxygen produced via electrolysis is significant compared to the value of the hydrogen due to the composition of water. This work presents a systematic methodology for designing a PtG project which co-utilizes hydrogen and oxygen to manufacture hydrogen and chemicals via integration with the natural gas infrastructure. A case study is developed and solved to demonstrate the applicability of the proposed methodology. The results of the case study show that significant value may be added by utilizing oxygen and the natural gas infrastructure.

“…The approach proposed by Panu et al (Panu et al 2019) may be used to minimize CO 2 footprint. The approach proposed by Topolski et al (Topolski et al 2018) may be used to monetize gases in case there are limited number of industrial plants nearby. One such configuration may look like the system depicted in Fig.…”

“…It is also worth noting that when sustainability issues (including water usage, fuel consumption, carbon footprint, and volatile organic compound emission) are included, the sustainability weighted return on investment is enhanced by 1–6 yr –1 % depending on the type of process modification undertaken to integrate and intensify the process . Further improvements can also be made when the process is integrated with adjacent facilities through an industrial symbiosis framework. − …”

The price fluctuations and unpredictability of a secure supply of fossil fuels create uncertainty in chemical production. One of the chemicals impacted by uncertainty is isopropanol, which has traditionally been manufactured from propylene. The shale gas boom has led to propylene shortages. Along with the high growth rate of propylene basedproducts, the propylene market has been tight and prices are expected to increase. Therefore, it is necessary to identify alternative, cost-effective, and sustainable pathways for the production of isopropanol. Isopropanol is projected to grow annually at a rate of about two percent across the globe. It is primarily used as a solvent in cosmetics, in personal care products, and in pharmaceutical products. Other uses include as a motor oil in the automotive industry, and as a cleaning and drying agent in the electronics industry. The objective of this research is to find alternative pathways to produce isopropanol and to select viable pathways while considering technology and economic factors. The methodology to achieve this objective includes branching and matching, prescreening, pathway selection, techno-economic analysis, and selecting the most sustainable pathway. A superstructure is created to show routes that can produce isopropanol from a variety of feedstocks. The techno-economic assessments of processes are also performed to compare the profitability of possible processes. The result shows that the propane dehydrogenation is still the best pathway to produce propylene. The result also reveals that the most promising pathway for isopropanol production is direct hydration. The advantages of the direct hydration method over the indirect hydration method include less dependency of iii annual ROI on the price of propylene (the feedstock of hydration processes), and avoidance of corrosion and environmental problems. iv DEDICATION To my parents v ACKNOWLEDGEMENTS I would like to acknowledge my academic supervisor, Dr. Mahmoud El-Halwagi, for always providing enthusiastic encouragement and valuable guidance of my research work.

“…El-Halwagi 31 further introduced a shortcut approach to multiscale atomic targeting for synthesizing the CHOSYN. Using the atomic targeting methodology, Topolski et al 32 synthesized the CHOSYN based on both new (tenant) and existing (anchor) plants based on the anchor−tenant approach. A follow-up work by Topolski et al 33 enhanced the anchor−tenant approach to further account for both mass and energy within a CHOSYN.…”

Discharge of industrial wastes constitutes one of the primary threats to the environment. A sustainable approach to handling industrial wastes is the adoption of integration and monetization schemes through the concept of an eco-industrial park (EIP). An EIP involving hydrocarbons is a particular case known as a carbon–hydrogen–oxygen symbiosis network (CHOSYN). Special features of the CHOSYN involve the conversion of wastes into value-added chemicals and the ability to perform multiscale targeting that benchmarks the performance from the atomic scale to large-scale implementation. Economic and mass conservation objectives have been used to guide the design of CHOSYNs. In this work, sustainability and safety are included as part of multicriterion objectives for the design of CHOSYNs. A rigorous and universal model for the optimization of a CHOSYN is developed with economic, sustainability, and safety objectives. An economic framework is used for reconciling the multiple criteria using the safety and sustainability weighted return on investment metric. The solution of the optimization formulation determines which plants participate and the extent of participation, the chemical pathways to convert wastes into value-added chemicals, and the allocation of the products to the users. The solution also reconciles the various design objectives. Subsequently, the proposed model is applied to a case study focusing on glycerol valorization.
