CFD‐Based Determination of Optimal Design and Operating Conditions of a Fermentation Reactor Using Bayesian Optimization Open
The efficiency of fermentation reactors is significantly impacted by gas dispersion and concentration distribution, which are influenced by the reactor's design and operating conditions. As the process scales up, optimizing these parameter…
Life Cycle Assessment of Fossil-Fuel based Carbon Monoxide Production: Comparison of Steam Methane Reforming and Partial Oxidation Open
This study conducts a life cycle assessment (LCA) to compare two fossil fuel-based carbon monoxide production processes: steam methane reforming (SMR) and partial oxidation (POX). For the SMR process, gate-to-gate data was generated throug…
Applying real options with reinforcement learning to assess commercial CCU deployment Open
Carbon capture and utilization (CCU), which emerged as a means to reduce anthropogenic carbon emissions, has been highlighted to close the carbon cycle and combat climate change. CCU involves utilizing or converting captured CO2 to create …
Mobile On Demand COVID-19 Vaccine Production Units for Developing Countries Open
Two years into the COVID-19 pandemic and more than one\nyear after\nthe approval of the first vaccine, bottlenecks in production and supply\nchain infrastructure continue to delay vaccination campaigns in the\nGlobal South. Mobile on Deman…
Flexible operation of modular electrochemical CO2 reduction processes Open
Electrochemical CO2 reduction (eCO2R) is an emerging technology that is capable of producing various organic chemicals from CO2, but its high electricity cost is a big economic obstacle. One solution to reduce the cumulative electricity co…

Early-stage evaluation of emerging CO<sub>2</sub>utilization technologies at low technology readiness levels Open
Three-step procedure for early-stage evaluation of CO2utilization technologies based on TRLs.
Power‐to‐X: Between Electricity Storage, e‐Production, and Demand Side Management Open
The common understanding of Power‐to‐X is exclusively the use of renewable electricity to manufacture products currently based on fossil sources. In this paper, it is argued that beyond such e‐Production many of these technologies also inc…
Design and sustainability analysis of a combined CO2 mineralization and desalination process Open
CO2 mineralization sequestrates CO2 in a form of mineral carbonate through chemical reactions of CO2 with metal oxide or alkaline solution. This process is attractive because it has no risk for a leakage of hazardous materials and requires…
Process systems engineering issues and applications towards reducing carbon dioxide emissions through conversion technologies Open
This paper reviews issues and applications for design of sustainable carbon dioxide conversion processes, specifically through chemical conversion, and the integration of the conversion processes with other systems from a process systems e…
