The study accomplished the process modeling using Aspen HYSYS software. To align with plant requirements, two correction techniques—optimization of parameter settings and updating binary interaction parameters (BIPs) in material library files—were employed to refine the purification plant model. These adjustments minimized deviations between simulation calculations and assessment analysis results to less than 5%. Subsequently, the accuracy and applicability of the modified model under diverse working conditions were validated by comparing and analyzing the corresponding working conditions with actual industrial data.

It uniquely incorporates variable thermal conductivity and variable mass diffusivity into the heat and mass transfer equations. The governing equations are solved using the bvp4c algorithm. Key findings reveal that higher squeezing reduces velocity, temperature, and concentration distributions. Increasing micropolar parameters enhances velocity, whereas variable thermal conductivity raises temperature profiles. Greater molecular diffusivity and chemical reaction parameters accelerate mass transfer rates, and the drag force intensifies with higher squeezing. Additionally, it is also noted that the squeezing parameter with a value (<i>c</i> = 0.2) demonstrated a stronger heat transmission rate (<i>Nu</i> = 0.33062) than the mass transfer rate (<i>Sh</i> = 0.2544).</p>\u0000 </div>","PeriodicalId":10083,"journal":{"name":"Chemical Engineering & Technology","volume":"49 6","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148100405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The flow inside the bed is largely independent of the Reynolds number and determined by the void space geometry. The flow in the freeboard is dominated by the presence of slowly dissipating jets downstream of the bed.

The article evaluates radiation penetration, temperature distributions, calcination degree, and CO<sub>2</sub> mass fraction in the system. Convective, radiative, and particle–particle conductive heat transfer are considered for dilute, moderate, and dense packing densities. Results show that packing density strongly influences both radiation and calcination. The study shows that the calcination degree decreases with increasing packing density.

Simulations on simple geometries and a full battery pack highlight system-level hazards.
