Tar Removal From Biomass‐Derived Syngas via Scrubbing: A Review on Process and Modeling
ChemBioEng Reviews, Volume 13, Issue 3, June 2026.This review article surveys contaminant formation and removal in biomass‐derived syngas, with a focus on tar scrubbing. It synthesizes evidence from benchmark plants and compares scrubbing configurations and solvents to assess performance and operating limits.

Simulation of Gas Sweetening Process using Extended NRTL and Stages Efficiency as Modeling Approach
EquilibriumGas sweetening is a process to remove CO₂ and H₂S from natural gas. The current established technology is by using Amine contactor where the solvent used is in form of Amine solution.

ChemistrySelect, Volume 11, Issue 21, 4 June 2026.Water activity (aw) was measured in eight DESs (10–90 wt% water). Strong DES–water interactions persist to ∼50 wt%, after which structure collapses toward aqueous‐like behavior. Redlich–Kister, Wilson, and COSMO‐RS models showed limited performance, whereas QSAR modeling using COSMOtherm‐derived σ‐profile descriptors significantly improved aw ...

Correlation of Viscosity of Aqueous Solutions of Alkanolamine Mixtures Based on the Eyring's Theory and Wong-Sandler Mixing Rule [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2013 A viscosity model, based on Eyring’s absolute rate theory combined with a cubic PR equation of state and Wong-Sandler mixing rule, has been proposed in order to correlate viscosities of aqueous solutions of alkanolamine mixtures at atmospheric pressure ...

AIChE Journal, Volume 72, Issue 5, May 2026.Abstract Despite extensive modeling efforts in extraction research, transient column models are rarely applied in industry due to concerns regarding parameter identifiability and model reliability. To address this, we analyzed uncertainty propagation from estimated parameters in a previously introduced column model and assessed identifiability via ill ...

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.ABSTRACT This study presents a comparative analysis of two optimization approaches: Sequential Iterative Optimization (SIO) and Non‐dominated Sorting Genetic Algorithm II (NSGA‐II) applied to the separation of ternary mixtures (1‐butanol, isobutanol, and 2‐butanol) using Dual‐Column Distillation (DCD) and Dividing‐Wall Column (DWC) processes. Through a

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 4, Page 726-739, April 2026.Abstract BACKGROUND Industrial fuel‐ethanol units must remove trace volatile congeners (acetaldehyde, ethyl acetate, carbon dioxide) to meet quality requirements. In Brazilian systems, a small heads column (“Column D”) is often placed above the stripper.
