Special Issue Information

Dear Colleagues,

Carbon capture has been recognised in the latest report by the Intergovernmental Panel on Climate change (IPCC) to be an essential technology to reduce global CO2 emissions and, therefore, to mitigate adverse climate change impacts. The immediate deployment of this technology is vital to meet the maximum 2 °C temperature rise threshold set at the Paris Agreement. Carbon capture can be integrated within a range of carbon-emitting industries, e.g., the energy sector, in order to minimise and/or eliminate the release of carbon dioxide into the atmosphere. Although there have been numerous studies in this realm, high associated costs are one of the key barriers in accelerated promotion of this technology across the world. As a result, there has been a growing trend in efforts made by both academia and industry to improve process efficiencies. This includes developing advanced materials and carbon capture systems and also devising intensified and energy-integrated processes.

In addition, carbon utilisation—although providing a less pronounced direct impact on climate change mitigation—plays a key role in incentivisation of accelerated commercial deployment of carbon capture technologies. Carbon utilisation has become more attractive within the past few years, with more processes being developed for large-scale deployment. Collectively, carbon capture and utilisation (CCU) is a major player in reducing CO2 emissions and creating a major incentive for large-scale commercialisation of the technology.  

This Special Issue on “Carbon Capture and Utilisation” aims to gather the most recent and outstanding works on all aspects related to the CCU. It strives to bring together high-quality research articles on the different aspects of CCU, including current status and remaining challenges. This Special Issue aims to inform on the most recent research and innovation progress made both in academia and industry. Topics include but are not limited to:

  1. Experimental and modelling works on various aspects of CCU;
  2. Design and synthesis, modelling and optimisation of CCU processes.

The main purposes of this project are to assess and to optimize the solubility of carbon dioxide (CO2) in an aqueous 30 wt% monoethanolamine-tetrabutylphosphonium methanesulfonate (MEA-[TBP][MeSO3]) new hybrid solvent. In this study, the viscosity and density of aqueous MEA-[TBP][MeSO3] hybrid solvents containing different amounts of [TBP][MeSO4] were determined. Meanwhile, Fourier Transform-Infrared (FT-IR) Spectroscopy was used to determine the presence of carbamate in aqueous MEA-[TBP][MeSO3] to prove that CO2 was absorbed by aqueous MEA-[TBP][MeSO3]. Response Surface Methodology (RSM) based on central composite design (CCD) was used to design the experiments and explore the effects of three independent parameters on the solubility of CO2 in aqueous MEA-[TBP][MeSO3]. The three independent parameters are concentration of [TBP][MeSO3] (2–20 wt.%), temperature (30–60 °C) and pressure of CO2 (2–30 bar). The experimental data was found to fit a quadratic equation using multiple regressions and analyzed using analysis of variance (ANOVA). The final empirical equation in terms of actual factors was deducted as mol fraction = 0.5316 − (2.76 × 10−4)A − (8.8 × 10−4)B + (8.48 × 10−3)C + (2.9 × 10−5)AB + (2.976 × 10−6)AC + (5.5 × 10−5)BC − (8.4 × 10−5)A2 − (3.3 × 10−5)B2 − (1.19 × 10−4)C2, whereby A = ionic liquid ([TBP][MeSO3]) concentration, B = temperature and C = CO2 pressure. An attempt was made to perform the experiments for solubility of CO2 in aqueous MEA-[TBP][MeSO3] to validate the removal of CO2 predicted by RSM. Based on a validation study, the experimental data showed a percentage error between 0.6% and 2.11% as compared to the predicted value of CO2 removal by RSM. Full article

The absorption process of CO2 by ethanolamine solution is essentially a dynamic system, which is greatly affected by the power plant startup and flue gas load changes. Hence, studying the optimal control of the CO2 chemical capture process has always been an important part in academic fields. Model predictive control (MPC) is a very effective control strategy used for such process, but the most intractable problem is the lack of accurate and effective model. In this work, Aspen Plus and Aspen Plus Dynamics are used to establish the process of monoethanolamine (MEA) absorption of CO2 related models based on subspace identification. The nonlinear distribution of the system under steady-state operation is analyzed. Dynamic tests were carried out to understand the dynamic characteristics of the system under variable operating conditions. Systematic subspace identification on open-loop experimental data was performed. We designed a model predictive controller based on the identified model combined with the state-space equation using Matlab/Simulink to analyze the changes of the system under two different disturbances. The simulation results show that the control performance of the MPC algorithm is significantly better than that of the traditional proportion integral differential (PID) system, with excellent setpoint tracking ability and robustness, which improve the stability and flexibility of the system.

This study attempts to measure the drag effect of carbon emissions on China’s economic growth by incorporating carbon emissions as an endogenous variable into an economic growth model and by relaxing the assumption that the size of the economy will remain unchanged. The drag effect of carbon emissions on the process of urbanisation is derived based on the intrinsic relationship between economic growth and urban development. Then, unit root and cointegration tests are performed using panel data from 30 provincial regions in Mainland China from 2003 to 2016 to prove and estimate the resistance caused by carbon emission in the process of urbanisation. Results show that the drag effect of carbon emission between 2003 and 2016 has a certain negative impact on the process of urbanisation in China. Due to the constraints of carbon emissions, the growth rate of China’s economic growth and urbanization level is 0.74% and 4.96% lower than that without constraints, respectively. Therefore, in the process of rapid urbanisation, formulating a reasonable carbon emission reduction strategy by the provincial government is conducive to the healthy and sustainable development of urbanisation.
