Optimum solvent concentration to lower energy demands for CO2 capture in refinery cases
Hartono, Ardi; Knuutila, Hanna K (Journal article, 2022)An open-access novel low-energy solvent HS-3 has been proposed and verified in the lab scale for post-combustion CO2 capture. The HS-3 solvent consists of a tertiary amine with a strong bicarbonate former and a primary ... -
Promoted Strong Bicarbonate Forming Solvents for CO2 Capture
Hartono, Ardi; Vevelstad, Solrun Johanne; Kim, Inna; Rennemo, Rune; Knuutila, Hanna K (Journal article; Peer reviewed, 2017)Effect of different promoters on performance of two bicarbonate forming solvents (HS1 and HS2) was studied in this work and results compared with the performance of 30 wt% MEA and CESAR1 solvents. Based on the results from ... -
Screening of Aqueous Solvent Systems for Post-Combustion CO2 Capture by Chemical Absorption
Krokvik, Iris Renate Tøkje (Master thesis, 2016)The atmospheric CO2 concentration we see today has likely not been seen before. As carbon dioxide is a strong greenhouse gas, this is a big red flag towards global warming. A higher mean temperature on earth would lead to ... -

Screening of strong bicarbonate forming solvents for CO2 capture
Hartono, Ardi; Vevelstad, Solrun Johanne; Ciftja, Arlinda; Knuutila, Hanna K (Journal article; Peer reviewed, 2017-03)Fifteen bicarbonate forming solvents were tested and compared to 30 mass% MEA using a screening apparatus. Additionally the pKa values of each of the solvents at room temperature were measured. The overall evaluation was ... -
Strong Bicarbonate Forming Solvents for Absorption of CO2 - Experimental Determination and Modelling of Vapor-Liquid Equilibria Data
Nøkleby, Christina (Master thesis, 2016)Absorption by amines provides a technology for CO2 capture. New solvents are of interest to ameliorate the process, and the two alkanoamines 2-piperidine-ethanol (2-PPE) and 1-(2-hydroxyethyl)-pyrrolidine (1-2HE-PRLD) were ... -
Vapor Liquid Equilibrium (VLE) in H2O-Amine-CO2 system
Ahmad, Rafiq (Master thesis, 2012)New experimental data for vapor-liquid equilibrium of CO2 in aqueous solutions of 3M/26.84% wt, 1M/9% wt and 0.1M/0.89% wt AMP (2-amino-2-methyl-1-propanol) and 1.5M PZ are reported from 313 to 393K. Low pressure/temperature ... -
Vapor Liquid Equilibrium Measurements of Two Promising Tertiary Amines for CO2 Capture
Pinto, Diego Di Domenico; Zahraee, Znar; Buvik, Vanja; Hartono, Ardi; Knuutila, Hanna K (Journal article; Peer reviewed, 2019)Post combustion CO2 capture is still a rather energy intense, and therefore expensive, process. Much of the current research for reducing the process energy requirements is focused on the regeneration section. A good ... -
