The Effect of Alkalinity, Magnesium and Ferrous on the Precipitation of Calcium Carbonate at Pre-Treatment Conditions of Mono Ethylene Glycol
(Master thesis, 2016)Mono ethylene glycol (MEG) is used to prevent formation of gas hydrate in the pipes transporting natural gas. The MEG is regenerated in a closed MEG loop, where water and salts are removed. The divalent ions are harder to ... -
Effect of Amine Volatility on Aerosol Droplet Development in Absorption Columns
(Journal article; Peer reviewed, 2017)In absorption processes aerosols are generated by spontaneous condensation or desublimation processes in supersaturated gas phases. Amine volatility is a vital screening parameter for amines to be used in CO2 capture. ... -
Effect of cobalt promotion on hydrotalcite-derived nickel catalyst for CO2 methanation
(Peer reviewed; Journal article, 2021)A series of cobalt-promoted Ni-Mg-Al hydrotalcite-derived catalysts were tested towards CO2 methanation reaction. The best among examined catalysts was the one with 1 wt% of cobalt in fresh hydrotalcite, obtaining 77% of ... -
Effect of Copper Catalyst Content and Zinc Promoter on Carbon Formation in the Direct Synthesis of Methylchlorosilanes
(Journal article; Peer reviewed, 2023)Direct synthesis of methylchlorosilanes (MCS) is a complex solid–gas–solid reaction where solid silicon (Si) reacts with chloromethane (CH3Cl) in the presence of a copper (Cu)-based catalyst, and coke formation by cracking ... -
The Effect of Crosslinking on the Physical Aging of PTMSP Membranes
(Master thesis, 2017)For post-combustion CO2 capture, membranes with high permeability and relatively high CO2/N2 selectivity are favoured to compete with the commercial amine-based absorption technology. With the highest known CO2 permeability, ... -
Effect of Cu2+ on deposition mechanism and structure of ZrO2-based conversion coatings on AA6060 aluminium alloys and their susceptibility to filiform corrosion
(Peer reviewed; Journal article, 2024)Zirconium oxide-based conversion coatings (CCs) were prepared from hexafluorozirconic acid, H2ZrF6, with and without CuII as an additive. The CCs were prepared on primary and recycled AA6060. The deposition mechanism, ... -
Effect of CuCl and Zn on Cu3Si Formation and Coke Deposition in the Direct Synthesis of Dimethyldichlorosilane
(Master thesis, 2020)The direct synthesis of dimethyldichlorosilane has been studied for more than 60 years, owing to its significance in the silicones industry. The direct process is a reaction of distinct complexity because of silicon taking ... -
