Special Issue Information

Dear Colleagues,

High Efficiency Processes for Gas Separation & Purification is currently a very important research area. It is an important processing step for most natural gas processing plants, bio-gas processing units, petroleum refineries, and chemical and energy production facilities (such as hydrogen production plants, synthesis gas plants, biomass-gasification units, and oil-sand operations). These industrial processes are also very important processing steps for producing clean energy and low-carbon fuels (including bio-fuels) into the future years.  In particular, the separation of CO2 (a major greenhouse gas) is gaining a great attention currently.  This dues to its releases into the atmosphere creating the climate change and global warming problems.   However, the captured carbon dioxide can be used directly in Enhanced Oil Recovery (EOR) techniques for the purpose of sustaining the current production of crude oil, which is a major energy source for many parts of the world.  For example, the oil produced from the IEAGHG Weyburn CO2-EOR project generates much less CO2 (approximately 30% to 50% of that from conventional oil productions).  Currently, the project has sequested for more than 35 million tons of CO2 since 2000, considered the largest CCUS project in the world.  

With a great important and need by the industry, a number of frontier research programs and projects have been developing worldwide. We therefore invite the submission on the disruptive technology development of High Efficiency Processes for Gas Separation & Purification. Technical reports, demonstration assessments, reviews, research articles, and communications in multidisciplinary relevant topics are welcome in this special issue.   We look forward to learning about your research work and results in this exciting research field.

MW-Assisted Regeneration of 13X Zeolites after N2O Adsorption from Concentrated Streams: A Process Intensification

N2O has a global warming potential about 300 times higher than CO2, and even if its contribution to the greenhouse effect is underrated, its abatement in industrial production’s tail gas has become imperative. In this work, we investigate the feasibility of the microwave (MW)-assisted regeneration of a 13X zeolite bed for N2O capture from tail gases. Several consecutive adsorption–desorption cycles were performed to verify the microwave heating effect on the zeolite’s adsorption properties. The results of the experimental tests, performed at N2O concentrations of 10, 20 and 40% vol, highlighted that (i) the steps are perfectly repeatable in terms of both adsorbed and desorbed amount of N2O, meaning that the MWs did not damage the zeolite’s structure, (ii) the presence of both H2O and O2 in the feed stream irreversibly reduces the adsorbent capacity due to nitrites and nitrates formation, and (iii) the presence of H2O alone with N2O still reduces the adsorbent capacity of the zeolites, which can be recovered through MW-assisted regeneration at 350 °C. Moreover, the MW-assisted TSA assured an energy and purge gas saving up to 63% and 82.5%, respectively, compared to a traditional regeneration process, resulting in effective process intensification.

Carbon capture and storage (CCS) is a key strategy to reduce carbon dioxide (CO2) emissions from industrial point sources. Gas absorption into aqueous amine solutions is an immediate technology for carbon capture that has been tested in many demonstration plants. One concern of using the amine-based carbon capture process is the environmental impacts and health risk caused by emissions of gaseous amines from the process to the atmosphere. This work applied the knowledge of air dispersion modelling to map out the atmospheric dispersion and resulting ground surface level concentration of gaseous amine, namely Monoethanolamine (MEA), from a coal-fired power plant (with a carbon capture unit) and in surrounding areas, in case of an accidental leaking of amine from the CCS system to the atmosphere. The chosen study area was centered on a coal-fired power plant in the province of Saskatchewan, Canada. The Environmental Protection (EPA) approved air pollution model (CALPUFF), together with meteorological and geophysical data were used for gaseous amine dispersion simulation. The results were presented, and the ground amine concentrations were found to vary with wind patterns (wind direction and wind speed). The maximum ground surface amine concentrations standard is 15.2 µg/m3. However, the results showed that when using the water wash unit, the MEA concentrations were well below the standard level, compared to those without the water wash unit. It is essential for CO2 capture plants located in highly populated areas to be equipped with water wash units. Full article
