Energy-Efficient Technologies for Reduction of Offshore CO2 Emissions

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1236810

This paper will discuss novel technologies for increasing the energy efficiency of offshore oil and gas platforms. Three case studies are in progress that are based on actual oil-producing platforms—two on the Norwegian Continental Shelf (NCS) and one in the Brazilian basin. The current focus is on ...

Flexible Combined Heat and Power Systems for Offshore Oil and Gas Facilities With CO2 Bottoming Cycles

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1183665

In this work different concepts are investigated for combined heat and power production (CHP) from offshore gas turbines. Implementation of such technology could improve energy efficiency of offshore oil and gas production and lead to reduced fuel consumption and resulting CO2 emissions. Offshore el...

Design and optimization of waste heat recovery unit using carbon dioxide as cooling fluid

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1183663

This paper describes design and optimization of a Waste Heat Recovery Unit (WHRU) for a power cycle which uses CO2 as a working fluid. This system is designed for offshore installation to increase gas turbine efficiency by recovering waste heat from the exhaust for production of additional power. Du...

Modelling and simulation of CO2 (carbon dioxide) bottoming cycles for offshore oil and gas installations at design and off-design conditions

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1046208

Improved energy efficiency is an issue of increasing importance in offshore oil and gas installations. The power on offshore installations is generated by gas turbines operating in a simple cycle. There is an obvious possibility for heat recovery for further power generation from the exhaust heat. H...
