Strategies for the Operation and Control of Heat Exchanger Networks
The continued high cost of energy has mandated that the Chemical Process Industries reduce operational and capital costs through process heat integration. However, the heat integration of process streams can lead to process structures that are difficult to operate and control. This paper addresses the control of heat exchanger networks and it shows the importance of dynamic simulations in the s...
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 کاملOptimization of Heat Exchanger Networks by Means of Evolution Strategies
This paper describes the adaptation of Evolution Strategies (ESs) for simulation based heat exchanger network synthesis. Due to space limitations the presentation is restricted to a brief overview of the application domain, the problems and pitfalls we encountered during the project and hints to solutions. Some of these problems are of general relevance for the application of Evolutionary Algor...
متن کاملControl structure design for optimal operation of heat exchanger networks
When only single bypasses and utility duties are used as manipulations, optimal operation of heat exchanger networks (HENs) can be categorized as an active constraint control problem. This work suggests a simple split-range control scheme to implement the optimal operation. The control structure can be found by solving an integer-linear programming (ILP) problem with two objective functions pro...
متن کاملSynthesis 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 ...
