Synthesis of Heat Exchanger Networks for Controllability
Heat exchanger networks are widely employed in the chemical processing industries to recover energy, resulting in reduced operating costs. Several methodologies can be found in the literature for the design of heat exchanger networks. Typical criteria are maximum energy recovery and minimum heat transfer area. However, the heat integration of process streams can lead to process structures that ...
متن کاملSynthesis of Multiperiod Heat Exchanger Networks Comprising Different Heat Exchanger Types
The following paper presents a mathematical formulation for the synthesis of heat exchanger networks (HEN’s), taking into account different types of heat exchangers (HE’s) and several conditions of operation. The model is developed using a disjunctive formulation into a preexistent multiperiod model. The Multiperiod-Disjunctive-MINLP was tested in an academic example comparing the results with ...
متن کاملOptimal Heat Exchanger Network Synthesis Including Heat Transfer Equipment Design
This paper presents an optimisation model for the synthesis of heat exchanger networks (HEN) including the detailed design of the equipments formulated as a decomposition method. Shell and tube pressure drops and fouling are considered, as well as mechanical aspects, like shell and tube bundle diameters, internal and external diameter of tubes, number of tubes, number of baffles, number of shel...
متن کاملAssessing the Controllability of Heat Exchanger Networks
Improving energy efficiency is probably the most generic issue for the process industry today, and process integration is a common tool to successfully achieve this. However, an increased level of process integration, usually implemented by re-circulation and other physical feedback structures, can increase the complexity of the dynamics drastically. This, in turn, implies increased control dif...
