Absorption and Desorption Study of Alkylamine Promoted DEEA Solvents for CO2 Capture
(Journal article; Peer reviewed, 2018)Three primary and two secondary mono-alkylamines, and a di-alkylamine (3 (Methylamino)propylamine, MAPA) were investigated in blend with a tertiary amine (2-(Diethylamino)ethanol, DEEA). The aim of the study was to ... -
Aspen Plus ENRTL Model for HS3 Blend, a Novel Solvent for CO2 Capture
(Peer reviewed; Journal article, 2023)Carbon Capture and Storage (CCS) is among the main available options to cut CO2 emissions from the industry and energy production sectors, but the high costs of current CCS technology still limit their large-scale ... -
Dividing wall columns for natural gas liquefaction plants
(Journal article; Peer reviewed, 2018)In order to meet current carbon dioxide emissions reduction challenges, natural gas processing and refining industries have to find the ways to minimize energy requirements of distillation operations. Building on foundations ... -
The Effect of Feeding Strategy on Butanol Production by Clostridium beijerinckii NCIMB 8052 Using Glucose and Xylose
(Peer reviewed; Journal article, 2018)We performed fed-batch fermentations of glucose and xylose mixtures producing butanol. Our aim was to develop a feeding strategy for coping with carbon catabolite repression (CCR) and sequential utilization problems as ... -
Effect of Uncertainties in Solvent Properties on the Techno-economic Performances of a CO2 Absorber
(Peer reviewed; Journal article, 2020)The use of computational models and simulation tools is vital for design and optimisation of CO2 absorption processes. When developing these tools, mathematical submodels such as models for physical properties and mass and ... -
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 ... -
Exergy Analysis of a Process Converting Power and Biomass to a Liquid Fuel
(Journal article; Peer reviewed, 2019)A power and biomass to liquid process (PBtL) via Fischer-Tropsch synthesis is exergetically analysed. Synthesis gas is generated through an entrained flow gasifier and extra hydrogen is produced through high temperature ... -
Heat Integration Study of CO2 Capture in Blue Hydrogen Production
(Peer reviewed; Journal article, 2023)Hydrogen is an energy carrier that can be used to develop a low-carbon economy: the hydrogen-based industry. For this purpose, a source of hydrogen is needed. Steam methane reforming (SMR) is the current benchmark to produce ... -
Modeling the Growth of Clostridium beijerinckii NCIMB 8052 on Lignocellulosic Sugars
(Peer reviewed; Journal article, 2018)To our knowledge, this is the first growth model of Clostridium beijerinckii NCIMB 8052 on glucose and xylose as representative lignocellulosic sugars, which considers the synergistic effects of sugars on the growth rate. ... -
Multi-Product Dividing Wall Columns: A Simple and Effective Assessment and Conceptual Design Procedure
(Journal article; Peer reviewed, 2011)The objective of this paper is to further exploit and demonstrate the potential benefits of a V-min diagram based analysis, using a fifteen component feed mixture as base case. Detailed explanations are given on how to ... -
A Novel CO2 Capture and Utilization Strategy by Enzyme Catalysis: Preliminary Assessment of Process Layout
(Peer reviewed; Journal article, 2022)Catalytic conversion of CO2 into fuels and valuable chemicals has gained large attention in the scientific and industrial research aimed at developing novel Carbon Capture and Utilization (CCU) processes. Among current ... -
Optimization of an Absorption-Based Biogas Upgrading and Liquefaction Process
(Journal article; Peer reviewed, 2019)The present work proposes a methodology for optimization of a liquefied biomethane (LBM) production plant. The LBM production plant comprises amine-based absorption upgrading followed by a single expander refrigeration ... -
Response Surface Methodology for Understanding Glucose and Xylose Utilization by Clostridium beijerinckii NCIMB 8052
