Exergetic assessment of energy systems on North Sea oil and gas platforms

摘要: Abstract Oil and gas platforms in the North Sea region are associated with high power consumption large CO2-emissions, as processing utility plants suffer from significant changes production rates performance losses over field lifespan. In this paper, a generic model of overall offshore system is described: its thermodynamic assessed by performing an exergy accounting rules thumb for oil derived. Simulations built conducted tools Aspen Plus®, Dynamic Network Analysis HYSYS®. 62–65% total destruction platform attributable to generation waste heat recovery system, 35–38% processing. The variability feed composition has little effect on split irreversibilities between both plants. rejection high-temperature gases flaring systems major contributor losses. These findings suggest focus efforts better use contained exhaust ways which compression can be improved.
