Achieving 50% weight reduction of offshore steam bottoming cycles
Mazzetti, Marit Jagtoyen; Hagen, Brede; Skaugen, Geir; Lindqvist, Karl Erik Artur; Lundberg, Steinar Henning; Kristensen, Oddrun Anglevik (Peer reviewed; Journal article, 2021)Adding a bottoming cycle to the gas turbines powering offshore oil and gas production plants allows additional power to be produced from recovered excess heat. Hence, the power demand of the platform can be met by burning ... -
Compact steam bottoming cycles: minimum weight design optimization and transient response of once through steam generators
Mocholí Montañés, Rubén; Skaugen, Geir; Hagen, Brede; Rohde, Daniel (Peer reviewed; Journal article, 2021)Compactness and weight minimization are key aspects for successful and widespread implementation of waste heat recovery steam cycles in off-shore oil and gas platforms due to the site weight and volume footprint constraints. ... -
Comparing Three Methods for Design Analyses of Rankine Cycle for Waste Heat Recovery from Natural Gas Compression
Deng, Han; Hagen, Brede; Nikolaisen, Monika; Andresen, Trond (Science et technique du froid;2020-1, Chapter; Peer reviewed, 2020)This study applies three methods for design of Rankine cycles utilizing waste heat in the oil and gas industry. The methods differ in the level of detail of heat exchanger model applied and in the flexibility with respect ... -
Dynamic Analysis of Energy Recovery Utilizing Thermal Storage from Batch-Wise Metal Casting
Andresen, Trond; Lingaas, Simon Johan Nilsen; Hagen, Brede; Nekså, Petter (Science et technique du froid;2020-1, Chapter; Peer reviewed, 2020)The thermal exergy contained in the liquid metal in ferroalloy production makes it an interesting source for energy recovery. The heat released during casting is rarely utilized today. This work investigates the feasibility ... -
Equation-oriented methods for design optimization and performance analysis of radial inflow turbines
Hagen, Brede; Agromayor, Roberto; Nekså, Petter (Peer reviewed; Journal article, 2021)This paper presents methods for design optimization and performance analysis of radial inflow turbines. Both methods are formulated in an equation-oriented manner and involve a single mathematical problem that is solved ... -
Gradient Based Design Optimization of a Radial Inflow Turbine
Hagen, Brede; Cavo, Matteo; Andresen, Trond; Nekså, Petter (Science et technique du froid;2020-1, Chapter; Peer reviewed, 2020)The expander is one of the key components of an ORC as the cycle efficiency strongly depends on the expander efficiency. This paper presents a method for design optimization of a radial inflow turbine (RIT) using a mean-line ... -
Techno-economic comparison of three technologies for precombustion CO2 capture from a lignite-fired IGCC
Roussanaly, Simon; Vitvarova, Monika; Anantharaman, Rahul; Berstad, David Olsson; Hagen, Brede; Jakobsen, Jana Poplsteinova; Novotny, Vaclav; Skaugen, Geir (Journal article; Peer reviewed, 2019)This paper compares the techno-economic performances of three technologies for CO2 capture from a lignite-based IGCC power plant located in the Czech Republic: (1) Physical absorption with a Rectisol-based process; (2) ...
