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 ...

Application of dynamic modelling and model‐based predictive control to enhance a cooling tower

The Canadian Journal of Chemical Engineering, EarlyView.
Model predictive control (MPC) applied to improve the operation of cooling towers. Abstract Model predictive control (MPC) differs from traditional feedback control by making predictions within a time horizon, providing better control actions for the process.

Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.

Aspen language specifications

ACM SIGPLAN Notices, 1977
ASPEN is a "toy" language that has been designed for use in the teaching of compiler construction and is therefore a curious amalgam of highly refined language features that manage to barely cover the full spectrum of algorithmic languages. One selection statement is made to do the work of IF-THEN-ELSE and CASE, but with certain severe restrictions on ...

3‐Reactor Chemical Looping System for Point Source CO2 Capture and Subsequent Conversion for Liquid Fuel Production

EcoEnergy, EarlyView.
This study presents a novel 3‐reactor chemical looping system for CO2 capture and subsequent utilization with biomass and natural gas for producing liquid fuels. Using Ca2Fe2O5\Fe2O3 oxygen carriers, it achieves 60% CO2 capture efficiency, ∼80% syngas purity, and autothermal operation, offering a scalable, carbon‐negative route to sustainable fuels ...

The dual influence of top‐down and bottom‐up processes on a mesopredator and the consequences for prey

Ecography, EarlyView.
Ecosystem dynamics are shaped by interacting top‐down and bottom‐up processes, yet their relative importance may vary through time following disturbances such as disease outbreaks and changes in apex predator communities. Using a 52‐year time series in south‐central Sweden, we examined how disease, apex predators, and prey availability jointly impact a

Responsive stimulation of the thalamus for idiopathic generalized epilepsy: Results of the randomized controlled NAUTILUS trial through 18 months

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to evaluate the safety and effectiveness of responsive thalamic stimulation as adjunctive therapy for drug‐resistant idiopathic generalized epilepsy (IGE) with generalized tonic–clonic seizures (GTCSs). Methods NAUTILUS is a prospective, multicenter, single‐blind, randomized sham‐controlled pivotal trial ...

Potential for monetisation and utilisation of wood raw material from pioneer tree species stands in the Czech Republic

Journal of Forest Science
Pioneer tree species in the Czech Republic include birch, alder and aspen. From an economic point of view, birch seems to be the most promising. Greater use of timber from pioneer tree species in higher value-added products is currently limited by the ...
