Abstract

In this paper, extensions to the MINLP superstructure formulation for multi-period heat exchanger network synthesis (HENS) proposed by Zhang (2006) which is based on the work by Yee and Grossmann (1990) are introduced. These modifications allow for simultaneous HENS including storage-subsystems with different characteristics. Besides stratified tanks and two-tank systems models for latent heat thermal storages (LHTS) and sensible storages are presented. Also, a sequential targeting procedure for the integration of storages is presented which combines insights from pinch analysis methods and a MINLP-formulation to calculate an approximation for optimal storage size and melting temperature. The results of the proposed integration procedure for thermal energy storages is demonstrated using a case study adapted from literature.
