CO2 MEA Capture: A Gaussian Process-Based Global Sensitivity Analysis
In this work, we present a variance-based global sensitivity analysis (GSA) using Gaussian process (GP) surrogate models to calculate the semi-analytic Sobol’ indices for a carbon dioxide (CO2), post-combustion capture (PCC) process. Using the open-source ROM-COMMA software library, the generated GP surrogate model enables accurate process output prediction, and calculation of the semi-analytic Sobol’ indices for GSA. We apply this methodology to a case study of a CO2 PCC process with 30 wt.%...
Lab-Scale Experimental Demonstration of Ca-Cu Chemical Looping for Hydrogen Production and In-Situ Co2 Capture from a Steel-Mill
This paper summarises lab findings on decarbonizing mixtures of inlet gases to simulate the composition of blast furnace gases from steel production and convert them into hydrogen-rich streams.
Preliminary Techno-Economic Evaluation of Blast Furnace Gas Utilisation with Ca-Cu looping Cycle Integrated with CO2 Separation by Partial Condensation
The iron and steel (I&S) industry, an energy-intensive sector and one of the significant contributors to global CO2 emissions accounted for approximately 2.6 Gt of direct CO2 emissions in 2019. BFG has a higher ratio of CO and CO2 compared to other I&S off-gases (coke oven gas and basic oxygen furnace gas). On the other hand, BFG has lower LHV than the other two off-gases due to higher N2 and CO2 concentrations. Therefore, effective CO2 removal from BFG is more cost-effective than...
CO2 Pipeline Operability and Safety Impacts

Techno-economic assessment of blast furnace gas pre-combustion decarbonisation integrated with the power generation
Aiming at the iron and steel industry decarbonisation with blast furnace gas (BFG) utilisation, this paper evaluates the techno-economic feasibility of the pre-combustion carbon capture with methyl diethanolamine.
Better Carbon Capture for Industrial Emissions – Enhancing CCUS in Europe in support of the Paris Agreement
This new policy brief argues that carbon capture, use and storage should be included in the list of technological priorities in EU countries’ climate policies.
Simulation Research of Leakage and Diffusion Disaster in High Pressure Supercritical CO2 Pipeline
In order to construct large-scale CO2 transportation pipelines and improve the application range of CCUS technology, it is very important to explore the disaster of supercritical CO2 leakage and diffusion in high-pressure pipelines. In this paper the industrial scale CO2 pipeline (length 257m， inner diameter 233mm) is taken as the research object， and the numerical model of supercritical CO2 leakage and diffusion in high-pressure pipeline is built by using computational fluid dynamics...
Experimental Investigation of the Characteristics of Supercritical CO2 during the Venting Process
Carbon capture utilization and storage (CCUS) is the technology with the greatest potential to decrease the content of CO2 in the atmosphere, which is the main contributor to global warming and can result in a significant number of environmental problems. The transportation of CO2 is the most important node in the CCUS chain and a pipeline is an economical and efficient means of transportation. In the process of CO2 pipeline building, a certain amount of venting devices should be installed to...
