Jan 01, 2013 Graphical Technique for Heat Integration in Batch Process As aforementioned, most of the graphical techniques in published literature rely on predetermined schedule, i.e. time is fixed a priori. This ultimately allows the analysis to be confined in a 2-dimensional space with relative ease, albeit at the expense of accuracy.

Sep 01, 1998 Extensive heat recovery from batch processes including the case of multiple stream matching can be accommodated by this model. An optimal schedule is found under the condition that heat is recovered in the mode of countercurrent exchange, but other types of heat exchange may be introduced after rescheduling.

Sep 05, 2014 Time Slice Model (TSM) is an existing model suitable to identify the potential for heat integration in batch processes. However, heat streams occurring during a heating or cooling process in a batch vessel cannot be depicted rigorously due to their time dependent temperature profile. Yet such streams can frequently be found in batch processes.

Oct 15, 2019 Provided batch processes are at temperature levels low enough to allow cost-effective sensible heat thermal energy storage (termed here Heat Storage, HS) using a suitable heat storage medium (HSM), heat integration can be achieved. Optimal integration of batch processes using HS is challenging however, as many degrees of freedom must be considered.

Feb 25, 2020 Process heat integration in batch processes is a complex problem given their time dependent behavior and need for thermal energy storage. In case of multi-product batch processes the complexity increases further. Due to its intricacy, the topic has so far been hardly addressed in literature.

Jan 10, 2014 As mentioned earlier, there are two heat exchange modes in thermally integrating batch processes: direct and indirect. All streams in any time interval exchange heat directly and for feasible heat transfer, a minimum approach temperature difference (Δ Tmin) must be specified.

Many current heat integration methods for multipurpose batch plants use a sequential methodology where the schedule is solved first followed by heat integration. This can lead to suboptimal results. In this paper, the heat integration model is built upon a robust scheduling framework.

This paper introduces a methodology for the heat integration of industrial batch processes. Based on Pinch Analysis principles, this methodology resorts to intermediate heat storage to prevent adverse effects on the operating flexibility. A systematic procedure, backed with a graphical representation, allows the determination of the minimum number of heat storage units and their range of ...

Mar 29, 2019 Batch processes have been extensively used in the process industries due to their appropriateness for small volume scale productions, high value-added products, as well as their adjustability to rapid market changes. Heat integration in a batch process can be carried out in two ways directly or indirectly. Direct heat integration is straight transfer of heat from hot to cold stream
