The effect of upstream inlet choking and surfactant addition on the performance of a novel parallel pipe oil-water separator
(Peer reviewed; Journal article, 2020)This paper reports the effect of inlet choking and addition of surfactant on the performance of a parallel pipe oil-water separator. These two issues can have a strong effect on oil-water separation in real hydrocarbon ... -
Effect of Various Parameters on the Thermal Stability and Corrosion of CO2-Loaded Tertiary Amine Blends
(Peer reviewed; Journal article, 2020)In this study, the thermal stability and corrosivity of various CO2-loaded tertiary amine blends in both aqueous and non-aqueous form in stainless steel cylinders were studied for combined acid gas and water removal. The ... -
Effect of Water Interactions on Polyvinylamine at Different pHs for Membrane Gas Separation
(Journal article; Peer reviewed, 2017)In our previous work, it was shown that the separation performance of the fixed-site-carrier polyvinylamine (PVAm) composite membrane increases exponentially with increasing relative humidity content in the gas. Through ... -
Effect of water wash on mist and aerosol formation in absorption column
(Journal article; Peer reviewed, 2018)Environmental issues regarding solvent emissions can hamper the realization of state of the art post combustion CO2 capture (PCCC). These emissions stem from the emitted flue gas from which CO2 has been recovered and are ... -

(Journal article; Peer reviewed, 2018)Novel strategies for thawing of pre-rigor frozen Atlantic cod (Gadus morhua) in water with air circulation, applying different and controlled temperatures are presented. After thawing (day 0) and after six days of storage ... -
Effects of K adsorption on the CO-induced restructuring of Co(11-20)
(Journal article; Peer reviewed, 2017)The location of potassium (K) on Cobalt (Co) and its effect on adsorption and adsorption-induced surface restructuring is important for understanding the deactivation of Co Fischer-Tropsch catalysts and the nature of the ... -
Effects of metal dusting relevant exposures of alloy 601 surfaces on carbon formation and oxide development
(Peer reviewed; Journal article, 2020)Ni and Fe are excellent catalysts for carbon formation, and industrial alloys are therefore susceptible to metal dusting corrosion; a costly issue in e.g. synthesis gas manufacture. The objective of this work is to better ... -
Effects of Ni-Co Ratio on Deactivation and Coke Formation in Steam Reforming of Hydrocarbon Impurities from Biomass Gasification with Ni-Co/Mg(Al)O Catalysts
(Peer reviewed; Journal article, 2022)Ni-Co/Mg(Al)O catalysts with different Ni-Co ratios (40-0, 30-10, 20-20, 10-30 and 0-40 wt%) have been tested for steam reforming of hydrocarbon impurities in a model biomass gasification syngas at relevant operating ... -
Effects of Oxygen Mobility in La-Fe-Based Perovskites on the Catalytic Activity and Selectivity of Methane Oxidation
(Peer reviewed; Journal article, 2020)The mechanism and structure requirements of selective and total oxidation of methane in a chemical looping process are both experimentally and theoretically examined on La1–xSrxFeO3−δ (x = 0, 0.2, and 0.5) and La0.5Sr0.5 ... -
Effects of polymer adsorption on the effective viscosity in microchannel flows: phenomenological slip layer model from molecular simulations
(Journal article; Peer reviewed, 2018)Molecular simulations (Dissipative Particle Dynamics - DPD) were used to quantify the effect of polymer adsorption on the effective shear viscosity of a semi-dilute polymer solution in microchannel Poseuille flow. It is ... -
Effects of Porous Supports in Thin-Film Composite Membranes on CO<inf>2</inf> Separation Performances
(Peer reviewed; Journal article, 2023)Despite numerous publications on membrane materials and the fabrication of thin-film composite (TFC) membranes for CO2 separation in recent decades, the effects of porous supports on TFC membrane performance have rarely ... -
Effects of post anaerobic digestion thermal hydrolysis on dewaterability and moisture distribution in digestates
(Journal article; Peer reviewed, 2019)Organic waste fractions such as sewage sludge, food waste and manure can be stabilized by anaerobic digestion (AD) to produce renewable energy in the form of biogas. Following AD, the digested solid fraction (digestate) ... -
Effects of Potassium and Copper Promoters on Iron Fischer-Tropsch Catalysts
(Master thesis, 2015)The demand for energy is an ever increasing problem in the world today. The need for more abundant energy sources to take over the role of crude oil is becoming more and more present. GTL processes (gas-to-liquid), which ... -
