  1. A Comprehensive Kinetic Study of the Reaction of SO2 with CaO by the Random Pore Model

    Hadi Moshiri, Bahram Nasernejad, Habib Ale Ebrahim and Mahboobeh Taheri

    Article first published online: 14 NOV 2014 | DOI: 10.1002/ceat.201400285

    For mathematical modeling of the SO2 removal reaction by CaO, the random pore model was applied to predict the reaction performance. The concentration dependency of this reaction was determined and the inherent rate constants were evaluated. Additionally, the product layer diffusivity was evaluated by comparing whole experimental conversion-time profiles with the model predictions.

  2. Hydrodynamic-Analogy-Based Modeling Approach for Distillative Separation of Organic Systems with Elevated Viscosity

    Tim S. Wolf, Christian Bradtmöller, Stephan Scholl and Eugeny Y. Kenig

    Article first published online: 13 NOV 2014 | DOI: 10.1002/ceat.201400372

    The influence of elevated liquid viscosity on the distillative separation of organic systems in structured packed columns is investigated using a modeling approach based on hydrodynamic analogies. Simulated separation efficiencies are compared to the results of independent experiments at different operating pressures and gas loads for two test systems.

  3. Particle Size Measurement of Metallic Iron in Reduced Materials Based on Optical Image Analysis

    Yongsheng Sun, Yuexin Han, Peng Gao and Yufan Mu

    Article first published online: 13 NOV 2014 | DOI: 10.1002/ceat.201300723

    Quantitative analysis of metallic iron particle size plays an important role in assessing the coal-based reduction process of refractory iron ores. According to the characterization of metallic iron particles, a powerful method is proposed to measure the size of metallic iron particles in reduced materials by optical image analysis. The obtained data was analyzed based on frequency and cumulative distribution.

  4. Replacement of CH4 in Hydrate in Porous Sediments with Liquid CO2 Injection

    Yu Zhang, Li-Jun Xiong, Xiao-Sen Li, Zhao-Yang Chen and Chun-Gang Xu

    Article first published online: 13 NOV 2014 | DOI: 10.1002/ceat.201300840

    Since kinetic data for CH4–CO2 replacement in porous sediments by liquid CO2 are still insufficient, experiments were performed under varying temperature and pressure conditions. The initial pressure has only a minor impact on the replacement rate. Reduced temperature leads to a lower replacement rate which is mainly affected by the fugacity difference of the CH4 hydrate decomposition and CO2 hydrate formation.

  5. Prediction of Air Specific Heat Ratios at Elevated Pressures Using a Novel Modeling Approach

    Arash Kamari, Amir H. Mohammadi, Alireza Bahadori and Sohrab Zendehboudi

    Article first published online: 13 NOV 2014 | DOI: 10.1002/ceat.201400261

    An accurate and efficient model based on least-squares support vector machines is developed for the determination of the air specific heat ratio at elevated pressures. The proposed model is able to predict the specific heat ratio with an accuracy adequate for many practical applications. The method is compared to previously published correlations and demonstrates better performance.
