Abstract
Floating, production, storage and offloading (FPSO) plants are facilities used in upstream petroleum processing. They have gained interest because they are more flexible than conventional plants and can be used for producing oil and gas in deep-water fields. In general, gas export is challenging because of the lack of infrastructure in remote locations. The present work investigates the possibility of integrating liquefaction processes on such facilities, considering four possible petroleum compositions, which differ in their contents of carbon dioxide, light and heavy hydrocarbons. The performance of the combined systems is analysed by conducting energy and exergy analyses. The integration of gas liquefaction results in greater power consumption and exergy destruction than in the baseline cases with compression and injection. However, the produced gas can be exported and sold, which results in higher economic benefits than in the conventional situation with gas injection.
