In this study, the snow separation technology for removal of carbon dioxide in natural gas based on CO₂ desublimation characteristics was introduced. The phase equilibrium calculation of CH₄-CO₂ and N₂-CO₂ system was carried out by using cubic equations of states (EOSs), and identified the SRK-EOS as the most accurate model under low-temperature, low-pressure conditions (<i>T</i> &lt; 250 K, <i>p</i> &lt; 3.2 MPa) for N₂-CO₂ system and the PR-EOS for CH₄-CO₂ system. Analysis of the CH₄-CO₂ system's frosting characteristics defined the operational window for CO₂ desublimation, leading to the development of a novel experimental separation system, and the process consistently reduced the CO₂ content in the top product gas to below 3% (molar fraction) under pressures of 0.7–1.2 MPa. This study conducted numerical simulation on the CO₂ desublimation process, which cannot be tested experimentally. Numerical simulations revealed that the nucleation rate and supersaturation increased with higher system pressure and feed CO₂ mole fraction, accelerating CO₂ ice crystal growth and consumption of gas-phase CO₂. Conversely, higher temperatures exhibited an opposing effect. These results confirm the technical feasibility of the CO₂ desublimation process for efficient natural gas decarbonization.</p>","PeriodicalId":49237,"journal":{"name":"Asia-Pacific Journal of Chemical Engineering","volume":"21 3","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apj.70216","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148193916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To better understand the exact pathway of the adsorption process, a prominent statistical physics formalism or grand canonical formalism has been proposed and used to evaluate the real-time experimental data by offering three parameter equations that could be significantly characterized by the specific adsorption reaction. Notably, there is a strong correlation between the real-time adsorption experimental data and the outcomes derived from the equations of the newly proposed statistical physics formalism model or Hill model. The observed parameters could offer an exact adhesion mechanism by indicating three important factors: (i) the actual number of adsorbed MB molecules at each active receptor site \u0000&lt;span&gt;&lt;/span&gt;&lt;math&gt;\u0000 &lt;mfenced&gt;\u0000 &lt;mi&gt;n&lt;/mi&gt;\u0000 &lt;/mfenced&gt;&lt;/math&gt; belonging to the structure of AC@CuO-NW adsorbents, (ii) the density of the occupied receptor sites per unit mass of the considered AC@CuO-NW adsorbents \u0000&lt;span&gt;&lt;/span&gt;&lt;math&gt;\u0000 &lt;mfenced&gt;\u0000 &lt;msub&gt;\u0000 &lt;mi&gt;D&lt;/mi&gt;\u0000 &lt;mi&gt;m&lt;/mi&gt;\u0000 &lt;/msub&gt;\u0000 &lt;/mfenced&gt;&lt;/math&gt;, and (iii) the energetic parameter—half saturation concentration \u0000&lt;span&gt;&lt;/span&gt;&lt;math&gt;\u0000 &lt;mfenced&gt;\u0000 &lt;msub&gt;\u0000 &lt;mi&gt;C&lt;/mi&gt;\u0000 &lt;mn&gt;1&lt;/mn&gt;\u0000 &lt;/msub&gt;\u0000 &lt;/mfenced&gt;&lt;/math&gt; with the binding energy—due to thermal agitation. The calculated values indicate that the selective separation of the particular MB dye from wastewater bodies was followed by monolayer physisorption due to the involvement of both hydrogen bonds and van der Waals interactions between the adsorbents and adsorbates.

Over the years, APJCE has undergone a substantial growth in readership, and quickly gained reputation among the chemical engineering society internationally. The manuscript acceptance rate over the life of the journal has averaged around 25% (out of an average of over 575 annual submitted manuscripts in the past 10 years). This acceptance rate is similar to the acceptance rate for most Chemical Engineering journals worldwide.&lt;/p&gt;&lt;p&gt;In the meantime, the publishing industry has also changed dramatically with recent years accelerating the transition towards open access publications. Open Access (OA) is a going trend. From the highly proactive communities in Europe, to the new players in Australasia, making research open access has become a policy focus for governments and national research funding bodies. As the journal publishing industry is experiencing significant revolution, we endeavour to meet the needs of readers, authors, editorial teams, librarians, universities and the scholarly and professional societies.&lt;/p&gt;&lt;p&gt;These encouraging statistics made us believe that the time is now right for APJCE to be part of the portfolio. Whilst becoming fully OA introduces a mandatory article publication charge for all substantive works (i.e., research articles, reviews) published in the journal, there are clear advantages to publishing OA with maximum impact and reach, and authors retain copyright of their article with a Creative Commons License.&lt;/p&gt;&lt;p&gt;Ten to fifteen years ago a full open access model used to be commonly associated with predatory or low-quality journals. This is simply no longer the case especially with many top journals now providing this option for their suit of publications. Gold OA journals in Wiley's portfolio are held to the same rigorous editorial standards as hybrid journals. APJCE is indexed as a trusted publication in the Directory of Open Access Journals (DOAJ). There would be no change to the editorial processes, policy and standards when the journal moves to a gold OA model. To reiterate, the editorial policies and academic rigour of APJCE will remain the same.&lt;/p&gt;&lt;p&gt;As we move to the new era of publishing, we would like to thank our authors who have submitted their work to the journal, and a special thank you to the many anonymous referees who have sacrificed their valuable time and devoted their academic rigour to maintain the standard, quality and reputation of our journal. We will endeavour to maintain a more streamlined procedure for progressing manuscripts through the system and keep the authors well informed at all stages.&lt;/p&gt;&lt;p&gt;We would also like to thank our Editorial Board members for their great contributions in the past years, particularly those who have organised Special Issues.

The study reveals that within the range of Reynolds numbers ( Re ) from 1 to 200, the mixing performance of spiral micromixers is superior to that of the unfolded wavy micromixers and T‐shaped micromixers. For spiral micromixers, there exists an optimal half‐axis length ratio. When the half‐axis length ratio is 0.65 and the Reynolds number is between 50 and 175, the mixing index increases by 4.3% to 25%.

This study systematically investigated DBP adsorption on three common nanomaterials—titanium dioxide nanoparticles (n‐TiO 2 ), multiwalled carbon nanotubes (MWCNTs), and carboxylated MWCNTs (MWCNTs‐COOH)—using comprehensive kinetic, isotherm, and thermodynamic analyses. Adsorption equilibrium was rapidly achieved on carbon‐based materials (8 h) compared to n‐TiO 2 (24 h), with adsorption capacities following the order MWCNTs &gt; MWCNTs‐COOH &gt; n‐TiO 2 . Kinetic modeling indicated that DBP adsorption on n‐TiO 2 is predominantly governed by physical processes, whereas adsorption on MWCNTs and MWCNTs‐COOH involves a combination of physisorption and chemisorption. The Freundlich isotherm model best described the adsorption for all three materials, suggesting heterogeneous multilayer adsorption. Although initial pH (5.3–7.9) had a negligible effect, the presence of humic acid significantly enhanced DBP adsorption on MWCNTs. Thermodynamic analysis revealed that the adsorption was spontaneous and endothermic for all materials. These findings provide crucial mechanistic insights into DBP‐nanomaterial interactions and highlight that carbon‐based nanomaterials, particularly MWCNTs, are highly effective for DBP removal from aquatic environments.","PeriodicalId":49237,"journal":{"name":"Asia-Pacific Journal of Chemical Engineering","volume":"21 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/apj.70199","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147900295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
