Application Algorithm Development of Pinch Technology in Heat Integration Problem

Ritesh Sojitra

Pinch technology is developing and its application is widening, reaching new horizons. The original concepts of pinch approach were quite clear and, because of numerous ways, application engineer gets confused among these numerous flexibilities. Therefore, there is a need for a rigorous and robust model which could guide the optimisation engineer on deciding the applicability of the pinch approach and direct sequential step of procedure in predefined workflow, so that the precision of approach is ensured. Exploring the various options of a novice handson algorithm development that can be coded and interfaced with GUI and keeping in mind the difficulties faced by designers, an effort was made to formulate a new algorithm for the optimisation activity. As such, the work aims at easing out application hurdles and providing hands-on information to the developer for use during preparation of new application tools. This paper presents a new algorithm, the application which ensures the designer does not violate basic pinch rules. To achieve this, intermittent check gates are provided in the algorithm, which eliminate violation of predefined basic pinch rules, design philosophy, and Engineering Standards and ensure that constraints are adequately considered. On the other side, its sequential instruction to develop the pinch analysis and reiteration promises maximum energy recovery (MER).
