Simulación de procesos con controladores lógico-programables (PLC’s)
(Asociación de Químicos e Ingenieros del Instituto Químico de Sarrià, 2014-04)
La realización de prácticas en el laboratorio de control de procesos presenta como mayor dificultad el coste asociado al funcionamiento del proceso, debido al consumo de reactivos, de energía o a la ...
Disseny de reactors fotoquímics: Descripció dels models d’emissió de llum per a reactors anulars. Part 2: Model de font extensa
(Asociación de Químicos e Ingenieros del Instituto Químico de Sarrià, 2009-07)
En el disseny d’un reactor fotoquímic és imprescindible conèixer bé la quantitat de llum que arriba a qualsevol punt del reactor, ja que aquesta influirà molt en la velocitat de la reacció. Aquest article ...
Generador de funciones periódicas con controlador lógico-programable (PLC)
(Asociación de Químicos e Ingenieros del Instituto Químico de Sarrià, 2015-04)
El análisis frecuencial de sistemas de control se basa en el conjunto de respuestas del proceso a señales senoidales que, en la mayoría de casos de los procesos habituales en la industria química, han ...
Disseny de reactors fotoquímics: descripció dels models d’emissió de llum per a reactors anulars. Part 1, models clàssics
(Asociación de Químicos e Ingenieros del Instituto Químico de Sarrià, 2009-05)
El disseny d’un reactor químic ha de contemplar normalment, a no ser que puguin simplificar-se, una sèrie de balanços: el de matèria, el d’energia i el de quantitat de moviment. A més d’aquests, un model ...
A study of deformation and strain induced in bulk by the oxide layers formation on a Fe-Cr-Al alloy in high-temperature liquid Pb-Bi eutectic
(Elsevier, 2018-06-01)
At elevated temperatures, heavy liquid metals and their alloys are known to create a highly corrosive environment that causes irreversible degradation of most iron-based materials. It has been found ...
Hybrid analytical surrogate-based process optimization via Bayesian symbolic regression
(Elsevier, 2024-01-09)
Modular chemical process simulators are widespread in chemical industries to design and optimize production processes with sufficient accuracy. However, convergence issues and entrapment in local optima ...
A tailored decomposition approach for optimization under uncertainty of carbon removal technologies in the EU power system
(Elsevier, 2024-05-22)
The broad portfolio of negative emissions technologies calls for integrated analyses to explore the synergies between them and the power sector, with which they display strong links. These analyses ...
Algebraic surrogate-based flexibility analysis of process units with complicating process constraints
(Elsevier, 2024-03-11)
Flexibility analyses are widespread in chemical engineering to quantify allowed deviations from nominal conditions. Standard approaches to perform flexibility analysis can be hard to apply if process ...
Switchable Electrostatically Templated Polymerization
(Wiley, 2022-09-26)
We report a switchable, templated polymerization system where the strength of the templating effect can be modulated by solution pH and/or ionic strength. The responsiveness to these cues is incorporated ...
Nb–C thin films prepared by DC-MS and HiPIMS: Synthesis, structure, and tribomechanical properties
(Elsevier, 2021-09-25)
Nanostructured Nb-C thin films were prepared by direct current magnetron sputtering (DC-MS) and high-power impulse magnetron sputtering (HiPIMS). The films were characterized in depth by X-ray diffraction ...
