Energy-Efficient Technologies for Reduction of Offshore CO2 Emissions

http://www.sintef.no/publikasjoner/publikasjon/?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

http://www.sintef.no/publikasjoner/publikasjon/?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

http://www.sintef.no/publikasjoner/publikasjon/?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

http://www.sintef.no/publikasjoner/publikasjon/?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...

Heat recovery from export gas compression: Analyzing power cycles with detailed heat exchanger models

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1038413

Offshore oil and gas production platforms release substantial amounts of heat to the sea. A major source of waste heat is the cooling unit for the compressed export gas. In this paper, the potential for power production from this heat source is analyzed. The emphasis was not only put on net power ou...

A flexible and robust modelling framework for multi-stream heat exchangers

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+966051

Heat exchangers are important units in most industrial processes. They involve physical phenomena such as condensation and evaporation including several boiling regimes. Different types of heat exchangers constructed for different applications may differ much in geometrical design. This work explain...
