An Analytical Design Model of a Vacuum Pressure Swing Adsorption Process for Biogas Upgrading

Chemie Ingenieur Technik, EarlyView.
A steady‐state model was developed for a vacuum pressure swing adsorption (VPSA) process comprising adsorption, depressurization, and evacuation steps. The resulting analytical plant design model provides the optimal adsorber height required to achieve a target product purity with maximum bed utilization.

WSPLK: A systematic approach to the thermodynamic characterization of light and heavy Mexican crude oil

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract A streamlined characterization framework (WSPLK) is presented for modelling complex reservoir fluids using cubic equations of state. The key methodological contribution is the introduction of a single global parameter ε directly into Pedersen's boiling‐point correlation, restoring pure‐component calibration and eliminating the need for ...

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

AI‐Enhanced Laser Manufacturing: A Social Life Cycle Perspective From the White Goods Industry

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainable manufacturing transitions require companies to demonstrate not only environmental and economic benefits, but also measurable advances in corporate social responsibility (CSR). Therefore, we propose using a guideline‐based Social Life Cycle Assessment (S‐LCA) aligned with UNEP (2020) and ISO 14075 (2024) to evaluate the social ...

“Effects of High‐Intensity Ultrasound on the Structural, Technofunctional, and Allergenic Properties of Groundnut (Arachis hypogaea L.) Protein Isolates: A Review”

Food Chemistry International, EarlyView.
ABSTRACT The growing global demand for sustainable, nutritionally balanced protein sources has intensified interest in plant‐derived proteins, particularly those derived from oilseeds such as groundnut (Arachis hypogaea L.). However, although groundnut protein isolates (GPIs) have high nutritional quality, they exhibit limitations in technofunctional ...

The effect of calcium and magnesium on the aggregation of a purple phototrophic bacteria mixed consortium

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND An essential aspect of applying Purple Phototrophic Bacteria (PPB) technology for wastewater treatment is the biomass separation from the aqueous phase. Ca2+ and Mg2+ have been used to enhance the aggregation of different biological matrices. In this paper, the effect of Ca2+ and Mg2+ on the aggregation of a mixed culture of PPB was
