- Mass Transfer in Molybdenum Extraction from Aqueous Solutions Using Nanoporous Membranes
Mehdi Ghadiri and Seyed N. Ashrafizadeh
Article first published online: 10 MAR 2014 | DOI: 10.1002/ceat.201300117
Non-disperse solvent extraction of molybdenum(VI) from aqueous solutions with PC-88A as extractant and a nanoporous hollow-fiber membrane contactor as extractor is modeled and simulated by computatio-nal fluid dynamics. The proposed simulation method is well-suited to predict the performance of solvent extraction of molybdenum in membrane extractors.

With the increasing consummation of natural carbon resources and higher CO2 emissions, CO2 removal is a key research topic. Studies show that the absorption of carbon dioxide from flue gas by blended amine solution has great potential for industrial environmental protection. This work investigates the optimal formula of blended amine solution based on absorption amount, rate, and loading.
- Prediction of the Induced Gas Flow Rate from a Self-Inducing Impeller with CFD
Cláudio P. Fonte, Bruno S. Pinho, Vania Santos-Moreau and José Carlos B. Lopes
Article first published online: 7 MAR 2014 | DOI: 10.1002/ceat.201300412
Compared to other methods promoting gas dispersion, hollow self-inducing impellers are an interesting solution when the recycling gas is costly or hazardous. A methodology for a simpler estimation of the gas flow rate from single-phase computational fluid dynamics simulations is proposed. The suggested hypothesis is valid for lower values of induced gas flow rate by comparison with experimental results.
- Control Parameterization-Based Adaptive Particle Swarm Approach for Solving Chemical Dynamic Optimization Problems
You Zhou and Xinggao Liu
Article first published online: 7 MAR 2014 | DOI: 10.1002/ceat.201300474
Optimal control problems are often encountered in areas such as economics, robotics, aeronautics, and chemical engineering. A unified framework for solving dynamic optimization problems is proposed. Furthermore, an adaptive particle swarm optimization method is introduced and combined with control parameterization to solve chemical dynamic optimization problems more efficiently.
- Preparation and Characterization of C60-Filled Ethyl Cellulose Mixed-Matrix Membranes for Gas Separation of Propylene/Propane
Haixiang Sun, Cheng Ma, Tao Wang, Yanyan Xu, Bingbing Yuan, Peng Li and Ying Kong
Article first published online: 7 MAR 2014 | DOI: 10.1002/ceat.201300667
Membrane separation technology is considered as a promising alternative approach for mixture separation of olefin and paraffin. Mixed-matrix membranes consisting of ethyl cellulose and C60 are cross-linked via UV irradiation. The effect of C60 content on separation properties of propylene/propane in terms of C60 particle morphology in the membranes is analyzed.
