Model simulation and optimisation for CCR platforming unit of Dung Quat refinery
Abstract
To improve efficiency and competitiveness, refineries need to optimise their operations to reduce production costs through crude oil selection and blending, definition of product structure, and energy saving, etc. The optimisation process can be conducted from unit level to the entire plant and supported by the simulation softwares. However, normally these models are "packages" which are software’s built-in or modelling by consultants and almost impossible to intervene directly in the thermodynamic mechanism of the process.
The CCR model (Refsim) currently used for the CCR Platforming unit of Dung Quat Refinery is built by KBC based on PetroSim software. This model, however, does not allow the engineers to conduct kinetic adjustment for optimisation. In this study, model simulation for the CCR Platforming unit in Dung Quat refinery has been built based on the expansion and adjustment of Krane kinetic model. After verification with real operation results, the simulation model will be used to predict the parameters of the process and evaluate the potential to optimise the operating conditions of the CCR Platforming unit in Dung Quat refinery.
