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 producingoil and gas in deep-water fields. In general, gas export is challenging because of the lack of infrastructure in remotelocations. The present work investigates the possibility of integrating liquefaction processes on such facilities, consideringfour 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 gasliquefaction results in greater power consumption and exergy destruction than in the baseline cases with compressionand injection. However, the produced gas can be exported and sold, which results in higher economic benefits than in theconventional situation with gas injection.
