- Abstract:
- ... The acoustic method is sensitive to agglomerations in fluidized bed reactors; however, a single acoustic sensor is not sufficient for industrial-scale reactors with regard to size, environmental noise, and signal pollution. Therefore, a multiacoustic sensor-based monitoring approach is investigated in this study. Different agglomeration warning models are established on the basis of each separate ...

- Abstract:
- ... The root causes underlying run-to-run variations in the synthesis of vertically aligned carbon nanotubes (VACNTs) by chemical vapor deposition can be attributed to the sensitivity of the process to small uncontrolled/unmeasured quantities of gaseous species in the reactor. Hence, universally applicable processing steps are needed to ensure consistency. Here, we quantitatively test the effectivenes ...

- Abstract:
- ... The analysis of remaining useful life (RUL) of systems and equipment enables the prevention of failures, so that effective maintenance can be performed in time to correct failures that are close to happening. The degradation signal of a variable can be used as a basis for estimating the RUL of a given system since this signal is modeled mathematically correctly. In this paper, the RUL of cyclic pr ...

- Abstract:
- ... Enhanced oil recovery with nanometer-sized particles is an attractive topic in the industry because of the various advantages brought about by the size. Since nanoparticles have not been applied widely on a field scale, core flooding tests are the best method to study and evaluate oil recovery improvement mechanisms. Different from previous review papers that discussed this research area case by c ...

- Abstract:
- ... In electrochemical processes such as electrodialysis or redox flow batteries, where ion exchange membranes (IEMs) play a critical role in process performance, energy losses can be reduced by minimizing the permeability of IEMs to water and salt. In pure, homogeneous polymer membranes, water permeability is known to be controlled by the size of the free volume elements. However, there is very limit ...

- Abstract:
- ... Mathematical modeling of chemical reaction kinetics has been proven to aid the development of new reactions and processes. Chemical kinetic modeling is a well-established principle in chemical engineering that uses fundamental knowledge of the reaction mechanism to predict conversion data. In pharmaceutical drug development, elementary-type kinetics are hardly common, because of the nature of the ...

- Abstract:

By integrating two powerful methods of density reduction and intrinsic dimensionality estimation, a new data-driven method, referred to as OLPP–MLE (orthogonal locality preserving projection-maximum likelihood estimation), is introduced for process monitoring. OLPP is utilized for dimensionality reduction, which provides better locality preserving power than locality preserving projection. Then, t ...

- Abstract:
- ... The chlorine from HCl can be recycled by catalytic oxidation during the industrial process, but excessive heat will be produced during the HCl catalytic oxidation, which leads to catalyst deactivation. Thus, a study of the reaction kinetics of HCl catalytic oxidation over a Cu-based composite catalyst is necessary. The influence of T values of 360–400 °C, nHCₗ/nO₂ values of 1–4, and FHCₗ₀/W values ...

- Abstract:
- ... The present work proposes a continuous electrocoagulation experimental setup for the removal of fluoride from water using aluminum electrodes. The experimental results showed that the proposed process can remove 97% of fluoride from 5 L of water with a concentration of 15 mg F–/L. Additionally, was verified that the applied voltage during the operation remains almost constant, indicating that this ...

We developed a methodology based on rheology and texture analysis to outline the physical–mechanical properties of aqueous dispersions of acrylic polymers belonging to three different classes: carbomers, acryloyldimethylta ...
