Thermodynamic Modeling of Aqueous Amine‐Electrolyte Solvents for CO2 Absorption

Greenhouse Gases: Science and Technology, Volume 15, Issue 3, Page 381-393, June 2025.
ABSTRACT The coupling process of carbon capture and utilization technology (CCU) that is gaining a lot of interest is called integrated CO2 capture–conversion (ICCC) where it is a part of the technological advancement aligning to one of the Sustainable Development Goals (SDGs) domains, which is SDG 13 (climate action).

Additives in Biphasic Hydroformylation: An Analysis of the Influence of the Interfacial Area

Chemie Ingenieur Technik, Volume 97, Issue 5, Page 378-394, May 2025.
Optimizing homogeneous biphasic hydroformylation offers significant potential for improving chemical efficiency by use of additives or by investigating different stirrer and reactor designs. Traditionally, efforts have focused on conversion rates and selectivity, but advanced techniques such as high‐pressure borescopy now allow detailed in‐situ ...

Simultaneous optimization of simulated moving bed adsorption and distillation for 2,3‐butanediol recovery

AIChE Journal, Volume 71, Issue 2, February 2025.
Abstract A combined simulated moving bed (SMB) and distillation separation scheme is developed to recover 2,3‐butanediol (BDO) from a dilute fermentation broth. The scheme was integrated into a lignocellulosic biorefinery that produces hydrocarbon fuels from corn stover with BDO as an intermediate.

Separation of benzene from cyclohexane by liquid-liquid extraction for a pseudo-ternary system with (sulfolane + 2-propanol) solvent: An experimental and modeling study

Results in Engineering
Since the condensation temperatures of Cyclohexane and Benzene are close, the distillation process is useless for extraction, and it must be done with the help of a solvent. Sulfolane is widely used as a solvent for extracting aromatic hydrocarbons.

A reinforcement learning approach with masked agents for chemical process flowsheet design

AIChE Journal, Volume 71, Issue 1, January 2025.
Abstract This study introduces two novel Reinforcement Learning (RL) agents for the design and optimization of chemical process flowsheets (CPFs): a discrete masked Proximal Policy Optimization (mPPO) and a hybrid masked Proximal Policy Optimization (mHPPO).

Model Development and Simulation of Anaerobic Digestion Process Using Aspen Plus

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
Cleaner energy, particularly biogas, is urgently needed. Biogas is generated via anaerobic digestion (AD), decomposing organic materials without oxygen. AD simulation models are appreciated for their cost‐effectiveness and predictive accuracy. This study creates a process model with Aspen Plus to simulate AD and biogas production.

Separation of Isoprenol‐Dimethyldioxane Mixture by Vacuum and Extractive Distillation

International Journal of Chemical Engineering, Volume 2025, Issue 1, 2025.
This study investigates the isolation of commercial isoprenol, a by‐product of large‐scale isoprene production. The challenge lies in separating isoprenol from an azeotropic mixture with 4,4‐dimethyldioxane‐1,3. The separation processes considered are vacuum and extractive distillation.
