A Segregated Targeting Algorithm for Concurrently Targeting and Designing of Batch Heat Exchanger Network

Batch heat integration is a critical aspect of process integration. Also, designing heat exchanger networks (HEN) is an important step in heat integration. This article presents a segmented strategy for concurrently targeting and constructing the HEN for the batch process. This method is built on the framework of segregated targeting of utilities in order to design HEN. The main objective is to provide a holistic picture of segregated targeting and build the HEN in a batch process. This method clearly captures the role of individual streams, which may be helpful in exploring reuse and recycling options within the streams. The concept of a segregated time-level grand composite curve was created in order to design a segregated heat distribution network (SeHDN). In a batch process, heat transfer can occur in two ways: direct and indirect. The developed method is capable of incorporating both types of heat transfer, which is further demonstrated through an example. SeHDN depicts the distribution of heat at different time intervals.
