Comparative CO₂Adsorption Analysis in Pure and Amine-Modified Composite Membranes

Polymer-Plastics Technology and Engineering (2016)

Sarah Farrukh Xianfeng Fan Arshad Hussain

In this study, the CO2 adsorption analysis in cellulose acetate–TiO2- and cellulose acetate–3-aminopropyl-trimethoxysilane TiO2-blended membranes was performed. The membranes were also characterized using scanning electron microscopy and Fourier transform infrared analysis techniques. The adsorption results indicated that 120 and 90°C were considered as optimized temperatures for regeneration of cellulose acetate–TiO2 and cellulose acetate–3-aminopropyl-trimethoxysilane-modified TiO2 membranes. The testing results revealed that adsorption capacity reached maximum at 3.0 bars. Validation of experimental results was performed by pseudo-first-order, second-order and intraparticle diffusion models. The correlation factor R2 represented that the second-order model was fitted well with the experimental data. The intraparticle diffusion model represented that adsorption is not a single-step process.

Photo-modulated regeneration of hypercrosslinked polymer adsorbents for water treatment

Separation and Purification Technology (2023)

Aotian Liu Xiuming Wei Shiliang Lin Liang Ding Yi Huang

Hypercrosslinked polymers (HCPs) are highly effective adsorbents for removing dyes from water. However, the regeneration of such adsorbents is typically achieved with energy-intensive thermal methods or with solvents that generate chemical waste. Here in this proof of concept study, we used HCPs loaded with azobenzene molecules (HCPs@Azo) that were developed in our previous work, and four types of dyes – Methyl Orange (MO), Methylene Blue (MB), Rhodamine B (RB), Uniblue A (UA), at concentrations ranging from 10 to 500 mg L−1, to demonstrate the feasibility of photo-modulated regeneration of HCP-based adsorbents. Azobenzene in HCP pores reduced dye adsorption by 4–31 %, but upon photo-isomerisation from trans to cis states, led to the desorption of 1.7–20 % dyes that were previously adsorbed. These desorption capacities were 71–209 % higher than using water for regeneration. Compared to the traditional method using organic solvents such as methanol to regenerate HCP-based adsorbents, our approach of photo-modulated regeneration led to the desorption of 50 % more MO and MB dyes. HCPs@Azo also demonstrated good reusability, showing comparable photo-modulated adsorption and desorption capacities after four cycles of UV–visible light irradiation. Results from this work can potentially pave the way for solvent-less regeneration of adsorbents, creating a waste-less adsorbent regeneration process.

Effect of CO2 Phase on Pore Geometry of Saline Reservoir Rock

Rock Mechanics and Rock Engineering (2022)

Peter D. Ameh Xiaoqiang Jin Xianfeng Fan Kenneth Imo‐Imo Eshiet Yong Sheng

Abstract The phase of CO 2 present in a saline reservoir influences the change of the pore geometry properties of reservoir rocks and consequently the transport and storage integrity of the reservoir. In this study, digital rock physics was used to evaluate pore geometry properties of rocks saturated with the different phaseCO 2 -brine under reservoir conditions. The changes in the pore geometry properties due to the different phaseCO 2 -brine-rock interaction were quantified. In addition to compression, CO 2 -brine-rock interaction caused a further reduction in porosity by precipitation. Compared to the dry sample, the porosity of the gaseous CO 2 -br sample was reduced the most, and was lower by 15% after saturation and compression. There was reduction in the pre-compression porosity after compression for all the samples, however, the reduction was highest in the gaseous CO 2 -br-saturated sample (13%). The flatness of pore surfaces was reduced, and pores became less rounded after compression, especially in supercritical CO 2 -br-saturated rock. The results from this research provide a valuable input to guide a robust simulation of CO 2 storage in reservoir rocks where different phases of CO 2 could be present.

Fault Diagnosis Using Multi-Source Information Fusion

Xianfeng Fan Ming J. Zuo

Fault diagnosis plays an important role in ensuring system reliability. Accurate fault diagnosis relies on data, fault features, diagnostic knowledge, reasoning, and decision-making. The following issues such as certainty and sufficiency of collected data, importance of features in diagnosis, and accuracy of diagnostic knowledge affect the accuracy of fault diagnosis greatly. Dempster-Shafer (D-S) evidence theory based multi-information fusion can provide a mechanism for representation of uncertain and imprecise information. However, it cannot directly handle the issues of evidence sufficiency, evidence importance, or conflicting evidences. An improved D-S evidence theory through the introduction of a fuzzy membership function, importance indexes, and conflict factors is reported in this paper. Experiment analysis results indicate that the proposed method is effective for practical fault diagnosis
