The impact of staged combustion on the operation of a precalciner cement kiln
(Doctoral thesis; Peer reviewed, 1999)
In this thesis, the impact of staged combustion on the operation of a precalciner cement kiln, is considered. Mathematical modelling and full-scale experiments at the Norcem cement works in Brevik, Norway, is the basis for ...
Process parameters affecting the sustainability of fermentative hydrogen production: A short review
(Journal article; Peer reviewed, 2011)
Anaerobic fermentation is regarded as the least energy intensive method for H2 production. Extensive literature on experimental attempts to achieve the highest possible theoretical yield (e.g. 4 mol H2/mol glucose) is ...
Burning chamber installation for increased use of alternative fuels at Norcem Brevik, Norway
(Conference object, 2006)
Assessment of sulphur emission at Norcem's cement kiln by use of 35S-tracer
(Conference object, 2001)
Although sulphur is not a major reacting species in making cement clinker, it is introduced as a pollutant in both the energy carrier (oil, coke, coal, household waste) and in the reactants (chalk, silica). Due to the ...
Nosé-Hoover simulations of aqueous mixtures of small alcohols
(Doctoral thesis; Peer reviewed, 1996)
We have performed constant energy and constant temperature equilibrium molecular dynamics simulations of model liquids of water, methanol, and ethanol, and of the binary aqueous mixtures of the alcohols at mole fractions ...
Pressure drop, flow pattern and local water volume fraction measurements of oil-water flow in pipes
(Journal article; Peer reviewed, 2009-11)
Oil-water flow in horizontal and slightly inclined pipes was investigated. The experimental activities were performed using the multiphase flow loop at Telemark University College, Porsgrunn, Norway. The two-fluid model ...
The influence of the experimental span of Time-resolved X-ray tomography on dynamic parameters in a fluidized bed
(Conference object; Peer reviewed, 2011)
Fluidized beds have presented some problems to experimentalists in the past due to their opaque nature . This problem has however been overcome by non-intrusive nor invasive measurement techniques. X-rays or Gamma rays ...
Anaerobic expanded granular sludge bed (EGSB) reactor for the removal of sulphide by autotrophic denitrification.
(Journal article; Peer reviewed, 2014)
The Removal efficiency, load and N/S molar ratio, of an EGSB reactor for autotrophic sulphide denitrification operated for 96 days, were studied. The reactor was operated at high inlet sulphide concentrations between 0.25 ...
Aspen Plus Simulation of Biomass Gasification with known Reaction Kinetic
(Conference object; Peer reviewed, 2015-11-25)
The energy from biomass can be utilized through the thermochemical conversion processes of pyrolysis and gasification. The Aspen Plus simulation tool is applicable for simulation of the gasification processes. The most ...
Gasification of Biomass for Production of Syngas for Biofuel
(Conference object; Peer reviewed, 2015)
Continuously increasing price of oil and gas, energy crisis and increased environmental consciousness towards the greenhouse gas emission have opened a new opportunity to the biomass, the oldest source of energy known to ...
