Comparing exergy and heat pump work in distillation systems

AIChE Journal, EarlyView.
Abstract This study compares the exergy supplied to a distillation column with the actual energy consumption of a heat pump‐assisted distillation (HPAD) system. It evaluates the reliability of exergy as a proxy for heat pump work demand in such systems.

Model‐based fault diagnosis in closed‐loop safety‐critical chemical reactors: An experimental study

AIChE Journal, EarlyView.
Abstract This experimental study investigates fault detection and estimation in a continuous stirred‐tank reactor (CSTR) system under closed‐loop feedback control, including an analysis of different manipulative inputs for temperature regulation. A novel fault diagnosis approach is proposed, combining residual signal analysis and T2 statistic for real ...

Lithium extraction from salt‐lake brines using dicationic ionic liquids: ePC‐SAFT modeling and molecular mechanisms

AIChE Journal, EarlyView.
Abstract This work proposes a novel strategy for enhancing Li+ extraction from salt‐lake brines with the high Mg2+/Li+ ratio using dicationic ionic liquid (DIL)‐based extractants. The ternary mixture of the DIL [DOMIM][Tf2N]2, tributyl phosphate (TBP), and dichloromethane (DCM) as a diluent achieved a higher single‐stage Li+ extraction efficiency (86 ...

Modeling heterogeneity in large‐scale bioreactors using the method of moments with a truncated normal distribution

AIChE Journal, EarlyView.
ABSTRACT Large‐scale bioreactors in industrial bioprocesses pose challenges due to extracellular concentration gradients and intracellular heterogeneity. This study introduces a novel approach integrating the method of moments with truncated normal distributions (MM‐TND) to model intracellular heterogeneity while maintaining computational feasibility ...

Predicting both thermodynamic and kinetic properties of crystallizing molecules via transformer‐based language model

AIChE Journal, EarlyView.
Abstract Crystallization is pivotal in the chemical and pharmaceutical industry, affecting particle stability, and drug release. Crystal size distribution (CSD), a critical attribute of the final dosage form, is determined by the molecular structure of the crystallizing entity.

Novel approach to modeling ultra‐low temperature frost formation using Computational Fluid Dynamics

AIChE Journal, EarlyView.
Abstract This study presents the development of a computational fluid dynamics model for predicting ultra‐low temperatures (less than −100°C). The frost formation rate was characterized using dimensionless numbers derived from operating conditions. To better capture the underlying physical phenomena of ultra‐low temperature frosting, various physical ...

Probabilistic approaches in civil engineering: generation of random fields and structural identification with genetic algorithms

, 2008
The inherent stochastic character of most of the physical quantities involved in engineering models has led to an always increasing interest for probabilistic analysis. Many approaches to stochastic analysis have been proposed. However, it is widely acknowledged that the only universal method available to solve accurately any kind of stochastic ...

Digital design and optimization of the integrated synthesis and crystallization process using data‐driven approaches

AIChE Journal, EarlyView.
Abstract This study presents a data‐driven modeling and multi‐objective optimization framework for an integrated section of continuous pharmaceutical manufacturing, focusing on flow synthesis and continuous crystallization. To address data scarcity and trade‐offs among product quality, efficiency, and environmental impact, the framework combines ...

Chlorine‐dopant dynamically stabilizes Cu0/Cu+ active sites for selective CO2 electroreduction to multicarbon products

AIChE Journal, EarlyView.
Abstract The electrochemical CO2 reduction reaction (CO2RR) to multicarbon (C2+) products faces significant challenges rooted in the high energy barriers of C–C coupling, which can be addressed through dopant‐mediated stabilization of Cu+ species on Cu catalysts.
