Synthesis of Multiperiod Heat Exchanger Networks Comprising Different Heat Exchanger Types

چکیده
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 the ones obtained with previous multiperiod models. The outcomes show that the cost of the HEN synthesized is greater than the one obtained with previous formulation, but a feasible operation in shell and tube HE, from the point of view of temperature crossing is guaranteed.

Synthesis of flexible heat exchanger networks for multiperiod operation
This paper addresses the problem of synthesizing heat exchanger networks that have the flexibility of coping with prespecified changes in flowrates, inlet temperatures and outlet temperatures in a finite sequence of time periods. A v multiperiod version of the mixed integer linear programming (MILP) transshipment model is presented which accounts for the changes in pinch points and utility requ...

At many circumstances, in heat exchange processes several exchangers were used with different cost laws due to their pressure ratings, materials of construction and exchange3r types. In such circumstances traditional methods of pinch technology can not be led to minimum total annual cost may cause some other disadvantages like more complexity or higher maintenance. In this research work a n...

متن کاملA Lagrangean Heuristic Approach for the Synthesis of Multiperiod Heat Exchanger Networks
In this work, we apply a decomposition technique to address the multiperiod heat exchanger network synthesis. Each period corresponds to changes in operating conditions, i.e. inlet temperatures and heat capacity flowrates. The problem size grows quickly with the number of streams and the number of periods resulting in a large scale problem to solve. In order to reduce the problem to a manageabl...
