The technologies for CO2 capture and storage (CCS) differ much in design, operation conditions, and the amount and nature of impurities in the captured CO2. The presence of impurities affects the thermophysical properties of CO2 significantly. In particular, properties such as phase equilibrium behavior...
...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 electric power is...
This paper investigates the possibilities of supplying offshore oil and gas platforms with power from the onshore power grid combined with offshore wind power. A system consisting of five oil and gas platforms connected to an offshore wind farm with a common VSC-HVDC link to the onshore power grid is...
Inception and propagation of streamers in a point-plane gap, with and without pressboard interfaces parallel to te field, have been studied. Curren and light emission have been recorded. Positive streamers propagate at about 2000-4000 m/s at voltages up to two times the minimum breakdown voltage. Above...
...oxidation and thermal stability at various conditions opposite to more classical time- and labor-consuming methods. The measurements were performed in both wet and dry environments in sealed stainless steel vials for new and preaged materials. The preaged materials were aged in advance at 110◦C and 100%...
We have considered a shock wave as a surface of discontinuity and computed the entropy production using nonequilibrium thermodynamics for surfaces. The results from this method, which we call the “Gibbs excess method” (GEM), were compared with results from three alternative methods, all based on the...
This paper investigates the ice formation and melting processes in a novel CTES unit using the commercial CFD software ANSYS Fluent 19. The storage unit is designed to operate as a peak shaving device integrated into the R744 circuit of a R717/R744 cascade refrigeration system in a food-processing plant...
...machinery and thruster configuration and thruster size selection. In order to obtain reliable results, it is crucial to apply engineering tools that realistically represent the flow physics and resulting hydrodynamic forces. Present computer tools are based on the assumption that wave drift- and current...
Petromaks 2 project "Formation and behaviour of thin oil films and evaluation of response methods including HSE", in the following short "Thin oil films" has the objective to achieve new knowledge more efficient and safe oil spill response operations for releases of condensates and light crude oils that may...
...chemicals, and has been proposed as a tool to assess differences in species sensitivities to chemicals between climatic regions. Arctic Calanus glacialis and boreal Calanus finmarchicus were exposed to mercury (Hg2+) under natural environmental conditions including sea temperatures of 2° and 10 °C, respectively...
