Realizing the potential high benefits of circular economy in the chemical industry: ethylene monomer recovery via polyethylene pyrolysis
(American Chemical Society (ACS), 2020-02-04)
Article
Accés obertThe concept of circular economy has gained wide interest in industry as a powerful strategy to reduce impacts while remaining economically competitive. Here, we explore the benefits of this approach in the chemical industry, ... -
Process screening framework for the synthesis of process networks from a circular economy perspective
(2021-01)
Article
Accés obertProcesses for recycling or reusing material resources have naturally appeared along with the history of technology development when need, resource scarcity, opportunities, and enabling technologies have combined conveniently ... -
Dynamic surrogate modelling for multistep-ahead prediction of multivariate nonlinear chemical processes
(American Chemical Society (ACS), 2020-07-30)
Article
Accés obertThis work proposes a methodology for multivariate dynamic modeling and multistep-ahead prediction of nonlinear systems using surrogate models for the application to nonlinear chemical processes. The methodology provides a ... -
An experimental approach to the optimization of the dosage of hydrogen peroxide for Fenton and photo-Fenton processes
(Elsevier, 2020-11-11)
Article
Accés obertThe determination of the hydrogen peroxide dosage scheme that minimizes hydrogen peroxide consumption while meeting the specified treatment outcome is crucial for Fenton and photo-Fenton processes. The challenge is building ... -
A viscosity-mediated model for relating gloss and film thickness of coatings
(2019-01-01)
Article
Accés obertFilm thickness determines many key coating properties including gloss. However, current literature hardly addresses the development of methods to directly correlate film thickness with gloss. Thus, the lack of accurate ... -
Outdoor air monitoring: Performance evaluation of a gas sensor to assess episodic nuisance/odorous events using active multi-sorbent bed tube sampling coupled to TD-GC/MS analysis
(Elsevier, 2019-08-03)
Article
Accés obertThe sampling of representative episodic events can be a difficult aspect (Caron et al.,2016, Ou-Yang et al., 2018), especially due to the short duration of episodic occurrences and its possibility of materializing during ... -
Data-driven soft-sensors for online monitoring of batch processes with different initial conditions
(Pergamon Press, 2018-10-04)
Article
Accés obertA soft-sensing methodology applicable to batch processes operated under changeable initial conditions is presented. These cases appear when the raw materials specifications differ from batch to batch, different production ... -
Removal of paracetamol using effective advanced oxidation processes
(2019-02-11)
Article
Accés obertFenton, photo-Fenton, and photo-induced oxidation, were investigated and compared for the treatment of 0.26 mmol L-1 of paracetamol (PCT) in a deionised water matrix, during a reaction span of 120.0 min. Low and high Fenton ... -
Optimal management of bio-based energy supply chains under parametric uncertainty through a data-driven decision-support framework
(2019-01-01)
Article
Accés obertThis paper addresses the optimal management of a multi-objective bio-based energy supply chain network subjected to multiple sources of uncertainty. The complexity to obtain an optimal solution using traditional uncertainty ... -
Systematic optimization approach for the efficient management of the photo-Fenton treatment process
(Elsevier, 2019-01-01)
Article
Accés obertThe photo-Fenton process is a photochemical process that has proved to be highly efficient in degrading new potentially harmful contaminants. Despite of this, scarce attention has been paid to the development of systematic ... -
A kinetic study for the Fenton and photo-Fenton paracetamol degradation in an annular photoreactor
(2018-09-18)
Article
Accés obertA kinetic model describing Fenton and photo-Fenton degradation of paracetamol (PCT) and consumption of hydrogen peroxide (H2O2) was proposed. A set of Fenton and photo-Fenton experiments (18 runs in total) was performed ... -
Outdoor air 1,3-butadiene monitoring: Comparison of performance of Radiello passive samplers and active multi-sorbent bed tubes
(2018)
Article
Accés obertA comparison was made between the relative performance of active and passive sampling methods for the analysis of 1,3-butadiene in outdoor air. Active and passive sampling was conducted using multi-sorbent bed tubes ...
