Abstract
Oil and gas offshore platforms present similar structural designs and include process operations such as separation, compression and pumping. They process fluids with various thermo-physical and chemical properties and they operate on fields with different characteristics. It is therefore not possible to suggest a standard system design of an offshore platform. In this work, the different technological alternatives for the separation and upgrading of oil and gas are first modelled and embedded in a general superstructure. Several plant configurations are then simulated for different petroleum compositions, based on actual data from Norwegian and Brazilian fields. Finally, the most promising pathways are optimised and ranked based on two main performance criteria, which are the total exergy consumption and separation efficiency. The results illustrate the clear trade-off between these two objectives and allow understanding the synergies between each process. For example, better oil and gas recoveries are achieved with higher power consumption for volatile petroleum or with greater heating demand for heavy ones.
