“…We thus employ an internal electric coil with a power-to-heat efficiency of 99% as a suitable heating source for such temperature values. 45,48,49 Transesterifier. To regulate the temperature inside the transesterifier, its jacket medium circulates through an external loop, with valves controlling the flow of hot or roomtemperature water as well as purging, depending on the desired heating or cooling mode.…”

The flexible operation of electrified chemical processes, powered by renewable electricity, offers economic and potentially ecological incentives, contributing to more sustainable chemical production. However, this requires a departure from the traditional steady-state operation, posing a challenge to process design and operation. We propose flexible biodiesel production by utilizing intermediate and final buffer tanks. We investigate the flexibility of three process configurations and compare the outcomes of their dynamic optimization strategies with those of a steady-state operation, considering a typical demand-side response scenario. For all strategies, we employ local gradient-based optimization and solve them using our open-source optimization framework DyOS. Our findings indicate that by incorporating intermediate tanks, we fully exploit the process flexibility potential, leading to energy savings of up to 29%. We also propose an implementation based on distributed optimization problems, yielding similar savings while significantly reducing computational costs by over 10-fold, thus paving the way toward online application.

“…Introducing electrical energy storage solutions to provide 24h operations will reduce efficiency. An effective impact on GHG emissions will occur only in a high renewables grid scenario [43]. In addition, there are high costs in retrofitting the current chemical reactors, especially in the chemical energy sector (which includes refineries).…”

“…At present, there are case studies missing but several companies offer electrical boilers for food manufacturing (e.g., Fulton Boiler Works, UK; LAARS Heating Systems Co., USA). In addition, a recent analysis concluded that especially the food sector has a high potential for electrification of boilers in the United States (Schoeneberger et al, 2022).…”

The utilization of heat is one of the foundations of modern food processing. At present, boilers that operate on fossil fuels are still dominating the generation of hot water, steam, and hot air in the food industry. In light of sustainability goals and carbon taxes as well as international efforts to reduce the dependence on natural gas, new technologies are needed to lower the greenhouse gas emissions related to thermal processing of foods. This review discusses important technologies that could serve as a replacement for conventional fossil fuel boilers in the future. These technologies are based on electricity, geothermal energy (direct/indirect use), and electricity to hydrogen conversion and include fuel cells, microturbines, engines, electrical boilers, heat pumps, radiation, and use of geothermal energy. The majority of these technologies are already available for implementation at larger scales and emissions are generally lower compared to burning fossil fuels. At present, major obstacles, such as low fossil fuel prices, still exist that prevent the widespread adoption of more sustainable heating technologies. However, the direct transformation of electrical energy and utilization of geothermal energy for heating purposes seem promising and should be more frequently installed in the future, whereas the use of H 2 obtained through electrolysis as a transportable source of energy may also serve as a source of thermal energy where it is useful to generate electricity and heat on the production site or where the availability of electricity is limited.
