Characterization of Coke Formation in The direct Synthesis of Dimethyldichlorosilane
(Master thesis, 2021)Den direkte syntesen av dimetyldiklorsilan har blitt brukt i silikonindustrien i over 60 år. Selv om prosessen er den mest praktiske og økonomiske måten å produsere dimetyldiklorsilan, så er prosessmekanismen fremdeles ... -
Characterization of Corrosion patterns of Stainless Steel in Diethylenetriamine (DETA)-CO2 and amine degradation products systems: and an Introductory Modeling Approach
(Master thesis, 2013)Diethylenetriamine (DETA) which has three amine functional groups and touted to be potential CO2 mitigation solvent has been shown to have high loading capacity, faster absorption rates, lower activation energy than the ... -
Characterization of Crude Oil-Water and Solid -Water Interfaces and Adsorption / Desorption Properties of Crude Oil Fractions: The Effect of Low Salinity Water and pH
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:173, Doctoral thesis, 2010)The reservoirs of conventional oil are rapidly depleting because of increased production and consumption of crude oil in the world. Mature and mostly depleted oil reservoirs require advanced recovery techniques to sustain ... -
Characterization of diethylenetriamine (DETA) as absorbent for CO2
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:130, Doctoral thesis, 2009)Absorption of CO2 with amine-based absorbents is an established and proven technology. Unfortunately, it is still very energy intensive and has high capital costs. The overall challenge when aiming at using this technology ... -

Characterization of solid particle suspensions with organic coatings in oilfield produced water
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:226, Doctoral thesis, 2008)Produced water is water trapped in underground formations that is brought to the surface along with oil or gas. In general, produced water is a mixture of dispersed oil in water (o/w), dissolved organic compounds (included ... -
Characterization of the Electrical Resistivity and Water Sorption Properties of a Semiconducting Swelling Tape
(Master thesis, 2018)In presence of moisture and localized field enhancements water trees might develop within the polymeric insulation of HV subsea power cables. Water trees tend to grow unnoticeable and deteriorate the insulation properties ... -
Characterization of vortical structures in a stirred tank
(Peer reviewed; Journal article, 2022)Data obtained from large eddy simulations of single-phase, turbulent flow of Newtonian and shear-thinning fluids in a baffled stirred tank reactor are considered to identify and characterize vortical structures. The ... -
Charge-Tuned CO Activation over a χ‑Fe5C2 Fischer−Tropsch Catalyst
(Journal article; Peer reviewed, 2018)We performed DFT calculations to understand CO activation over a χ-Fe5C2 Fischer–Tropsch catalyst. The χ-Fe5C2 catalyst exhibits unique CO activation behaviors, and the BEP relation is nearly valid for this system. The ... -
Chemical Additives as Flow Improvers for Waxy Crude Oil and Model Oil: A Critical Review Analyzing Structure–Efficacy Relationships
(Journal article; Peer reviewed, 2022)Waxy crude oil has become a crucial unconventional oil alternative owing to the depleting conventional oil resources. However, ascertaining flow assurance in a waxy crude oil pipeline at low temperatures is challenging due ... -
