Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Under low reagent dosage, the flotation performance of diesel as a collector was enhanced, and the synergistic mechanism of diesel blended with oleic acid and CTAB was investigated. Results showed that compared to pure diesel, the oleic acid blended system (Blend A) increased clean coal yield by 81.52% to 92.24%, while the CTAB blended system (

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Influence of Wall Deformation Structure on the Liquid Film Flow Behavior Under Turbulent Conditions
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT To explore the influence of typical wall deformation structure in the scrubbing‐cooling tube on the liquid film, this paper studied the liquid film flow behavior on the riblet walls with representative riblet radii and compared them with the flat wall. Under different liquid film Reynolds numbers (Rel = 8.3 × 103 ~ 3.14 × 104), the liquid film
