Abstract EN
We show how a multiobjective bare-bones particle swarm optimization can be used for a process parameter tuning and performance enhancement of a natural gas sweetening unit.
This has been made through maximization of hydrocarbon recovery and minimization of the total energy of the process as the two objectives of the optimization.
A trade-off exists between these two objectives as illustrated by the Pareto front.
This algorithm has been applied to a sweetening unit that uses the Benfield HiPure process.
Detailed models of the natural gas unit are developed in ProMax process simulator and integrated to the multi-objective optimization developed in visual basic environment (VBA).
In this study, the solvent circulation rates, stripper pressure and reboiler duties are considered as the decision variables while hydrogen sulfide and carbon dioxide concentrations in the sweetened gas are considered as process constraints.
The upper and lower bounds of the decision variables are obtained through a parametric sensitivity analysis of the models.
The Pareto sets show a significant improvement in hydrocarbon recovery and a decent reduction in the heat consumption of the process.
