(80f) High-Fidelity Modeling and Optimization of Natural Gas Dehydration and Liquid Recovery Plants
We first show the comprehensive data reconciliation and modelsâ validation performed to ensure that the modelsâ predictions match the real plant behaviour. We then present how the advanced optimization features result in the best operational strategies for the natural gas liquids recovery system. We also show the optimization analysis carried out for maximizing the adsorption cycle time for the dehydration unit while minimizing the total heating duty required for the regeneration of the molecular sieve beds.
The optimization analysis has led to an estimated increase in annual net revenue of natural gas liquid recovery unit by 6 MM USD as a result of maximized liquid hydrocarbon production and lower operating costs related to steam and refrigeration.
