Heat Integration of Batch Processes

Thermal Energy Storage Integration Based on Pinch Analysis – Methodology and Application

“…In this example, a chemical batch process as given in has been chosen to show the overall workflow. The process is shown in Fig.…”

“…Process schema (a) of batch distillation chemical process and associated ISSP (b) based on highest priority streams (Tab. ).…”

“…This Gantt chart assumes no overlapping of consecutive batches and is used in this application example. However, it must be noted that the original publication used a combinatorial optimization method to determine the DHR potential between batches that overlap during the production cycle. A fixed repetition cycle was used and the total amount of internal heat recovery was found to be 1965 kWh.…”

Heat integration of intermittently available continuous streams in multipurpose batch plants

“…There are some other works considering both operating and capital costs to optimize the economic performance (Liu et al, 2011;Pinto et al, 2003). Uhlenbruck et al (2000) improved the OMNIUM method developed by Hellwig and Thöne (1994) for HEN synthesis. Applying the improved OMNIUM to an example batch process shows a 20% increase in the amount of heat recovery.…”
