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.

A modified NRTL model for accurate phases equilibria: Part II: application to liquid–liquid equilibrium up to plait point

Results in Engineering
This study presents a modified NRTL model that significantly improves the accuracy of liquid–liquid equilibrium (LLE) predictions for multicomponent systems. Unlike classical thermodynamic models, which based only on binary parameters and often fail near

Understanding Water Activity in Deep Eutectic Solvents: Experimental Screening, Thermodynamic Modeling, and QSAR Predictions

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 ...

Artificial Neural Network Surrogate Modelling for Predicting and Optimising CO2 Conversion to Methanol Under Uncertainty

CAAI Transactions on Intelligence Technology, Volume 11, Issue 3, Page 633-645, June 2026.
ABSTRACT This study introduces a data‐driven surrogate modelling framework that combines an artificial neural network (ANN) with particle swarm optimisation (PSO) and a genetic algorithm (GA) to optimise methanol production under uncertain conditions.

Transient modeling of extraction columns: Parameter estimation, uncertainty analysis, and operation optimization

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 ...

Energy‐Efficient and Sustainable Design Optimization for Ternary Mixture Separation: A Comparative Analysis of Sequential Iterative Optimization and Non‐Dominated Sorting Genetic Algorithm II

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.

A modified NRTL model for accurate phases equilibria: Part I: application to vapor–liquid equilibrium

Results in Engineering
This study presents a modified Non-Random Two-Liquid (NRTL) model that enhances vapor–liquid equilibrium (VLE) correlations across binary and ternary systems and prediction of VLE in quaternary systems. The improvement is due to a structural modification
