“…238 This statement is confirmed by Walmsley et al, 229 mentioning that future works will be focused on generating solutions for complex problems involving simultaneous approaches and including new technical indicators and sustainability targets through process integration techniques. In this sense, the recently proposed graphical tool for calculating exergy losses in heat exchange networks 239 manifested the growing interest in studying and advancing process integration toward the described approach.…”

These days, developing sustainable chemical facilities to generate biofuels, energy, bioproducts, and value-added chemicals has attracted attention. The above involves changing the traditional conception of transformation processes into more sustainable production based on the green chemistry principles, renewable energies, and the triple dimensions of sustainable development. Consequently, the addition of sustainability issues in process synthesis, analysis, and optimization of bioprocesses has become increasingly noteworthy. This study reports a literature review concerning the sustainable chemical process design framework based on process synthesis, analysis, and optimization methodologies. Studies on biorefinery/process synthesis approaches are analyzed and compared, offering a detailed overview of selected literature. These included hierarchical, mathematical, and mixed approaches. This review also outlined indexes and indicators for measuring sustainability in process design considering exergetic/energetic, environmental, economic, and safety aspects. It is worth mentioning the role that exergetic metrics are expected to play in measuring global process sustainability. Finally, the current research gap of process integration is analyzed, considering pinch analysis techniques, simultaneous heat and mass integration, and hybrid intensification−integration approaches.

“…Additionally, there is an option for stream allocation to minimize the utility demand. Abdelouadoud et al 14 used the TAM for graphical determination of the HS system characteristics (temperature, volume, connections, heat transfer, etc.). Thus, they converted the batch heat integration problem into a problem related to continuous processes with constant parameters.…”

Heat storage is an important part for heat integration between nonrepeatable batches. This article suggests a new approach in the design of heat storage exchange network for heat integration between nonrepeatable batches. This approach is built on the TRANSSHIPMENT method. The main idea is reusing the waste heat from stream segments that are designed to exchange heat with utilities. These extracted stream segments are added to every upcoming time slice as new energy streams. The possible heat exchange between extracted segments and existing streams in every Time Slice is based on the suggested algorithm which includes the main rules of the Pinch technology. All possible matches are potential heat storage units or subsystems. The efficiency of heat recovery increases if the schedule of nonrepeatable batches is repeated every day. That makes a great impact on the production costs. Otherwise, as it is in the given case study, the waste heat reduction is small and cannot support the investment for the solution. The reduction of hot utility in the presented case study is 43.5% and the reduction of cold utility is 12.1% in the start-up period of the plant (58.94 hours).

Heat integration of repeatable batches with heat storage is a complex problem. This article suggests a new approach in the determination of possible heat storage for repeatable batch processes. This approach is based on the TRANSSHIPMENT method. The surplus heat and cold from streams and stream segments are added to the already designed heat exchanger networks for each time slice. These streams or stream segments from other time slices are supposed to match with streams or stream segments in a particular time slice. The heat content together with the changed supply and target temperatures of streams, and the minimal temperature difference for heat exchange are the main parameters used in the suggested method. The proposed technique creates a heat exchanger network between streams and potential heat storage at different times. The solution is a secondary network of heat storage units. The benefit in design of the solution is heat recovery for 11.51 kW per cycle of the analyzed case study. The annual heat recovery by cooling and heating separately is 4488.1 kW. As a result of suggested solution, the waste heat is minimized for approximately 13.5%.
