ATR-FTIR Model Development and Verification for Qualitative and Quantitative Analysis in MDEA–H2O–MEG/TEG–CO2 Blends
Shoukat, Usman; Baumeister, Eva; Knuutila, Hanna K (Journal article; Peer reviewed, 2019)A Fourier transform infrared (FTIR) spectroscopy method was developed to identify and quantify various components in an amine-based combined acid gas and water removal process. In this work, an attenuated total reflectance ... -
Combined subsea hydrate control and H2S removal
Shoukat, Usman (Doctoral theses at NTNU;2019:127, Doctoral thesis, 2019)In Norway natural gas production mostly comes from offshore facilities and contains impurities such as acid gases (hydrogen sulfide (H2S) & carbon dioxide (CO2)), water vapor, and mercury, etc. These impurities can cause ... -
Effect of Various Parameters on the Thermal Stability and Corrosion of CO2-Loaded Tertiary Amine Blends
Shoukat, Usman; Knuutila, Hanna K (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 ... -
Study of various aqueous and non-aqueous amine blends for hydrogen sulfide removal from natural gas
Shoukat, Usman; Pinto, Diego Di Domenico; Knuutila, Hanna K (Journal article; Peer reviewed, 2019)Various novel amine solutions both in aqueous and non-aqueous [monoethylene glycol (MEG)/triethylene glycol(TEG)] forms have been studied for hydrogen sulfide (H2S) absorption. The study was conducted in a custom build ... -
Thermal stability and corrosion of tertiary amines in aqueous amine and amine-glycol-water solutions for combined acid gas and water removal
Shoukat, Usman; Baumeister, Eva; Pinto, Diego Di Domenico; Knuutila, Hanna K (Journal article; Peer reviewed, 2018)Thermal stability and corrosion of seven tertiary amines (20 wt.%) solutions in water and water-glycol [ethylene glycol (MEG)/tri-ethylene glycol (TEG)] loaded with CO2 in stainless steel reactors has been studied for ... -
Vapor liquid equilibrium of pure and aqueous Methyl diethanolamine (MDEA), 2-Dimethylmonoethanolamine (DMMEA), N-Methylmonoethanolamine (MMEA) and 1-(2-Aminoethyl)piperazine (AEP): Experimental results and modeling
Svendsen, Hallvard Fjøsne; Jonassen, Tom Øystein; Hartono, Ardi; Shoukat, Usman; Francois, Maxime Herve Jean-Jacques; Knuutila, Hanna K; Kim, Inna (Peer reviewed; Journal article, 2023)This work presents new vapor-liquid data for the pure components 2-dimethylmonoethanolamine (DMMEA) and N-methylethanolamine (MMEA) and for the binary systems of aqueous methyldiethanolamine (MDEA), DMMEA, MMEA, and ...
