| Abstract/Summary |
The paper deals with some problems of targeting heat exchanger networks (HENs), such as a choice of the algorithms from Pinch Analysis (PA) technology for targeting HENs of multipass apparatus, and a new approach for calculating heat recovery for nonpoint utilities. The analysis of approaches from PA was given and examples were presented to show that some algorithms could yield inaccurate or even mistaken results. Comments were formulated on the choice of proper algorithms. In regard to heat recovery for nonpoint utilities a simple graphical approach was developed following concepts from wastewater minimization. The approach requires only basic information for process streams to yield the minimum cost at minimum flow rates of nonpoint utilities. It also provides information on limiting outlet temperatures of utilities that ensure feasible heat recovery with minimal flow rates of utilities.
