Effect of Gasifying Medium on the Coal Chemical Looping Gasification with CaSO4 as Oxygen Carrier
Publication date: Available online 16 September 2014 Source:Chinese Journal of Chemical Engineering Author(s): Yongzhuo Liu , Weihua Jia , Qingjie Guo , HoJung Ryu The chemical looping gasification uses an oxygen carrier for solid fuel gasification by supplying insufficient lattice oxygen. Effect of gasifying medium on the coal chemical looping gasification with CaSO4 as oxygen carrier is investigated in this paper. The thermodynamical analysis indicates that the addition of steam and CO2 into the system can reduce the reaction temperature, at which the concentration of syngas reaches its maximum value. Experimental resu...

The impact of focused degree projects in chemical engineering education on students’ research performance, retention, and efficacy
This study's purpose is to explore the relationship between sequential chemical engineering degree projects and students’ performance, engineering efficacy, multidisciplinarity, and retention. The projects for this education for chemical engineers research are thematically focused laboratory experiments embedded in a four-year chemical engineering program. Each project component is connected to the next, is increasingly complex as courses advanced, and is aligned with essential course content. This connectivity enables students to participate in logically sequenced experiments that culminate in well-developed senior labo...

Environmental and public health risks associated with chemical waste from research and educational laboratories in Dar es Salaam, Tanzania
This study presents a preliminary assessment of waste management practices in eleven laboratories of six educational and research institutions in Dar es Salaam, Tanzania. Categorical questionnaires were administered to 52 laboratory personnel to assess their awareness of health and environmental risks of chemical waste and the waste management practices. A chemical analysis was carried out to determine the nature, amount and composition of waste so as to assess the associated risk of environmental contamination and human exposure. The study found that liquid waste generated by the surveyed laboratories was mostly acidic in...

Role of chemical hardness in the adsorption of hexavalent chromium species onto metal oxide nanoparticles
Publication date: 1 August 2015 Source:Chemical Engineering Journal, Volume 273 Author(s): Yong Jae Suh , Jin Wook Chae , Hee Dong Jang , Kuk Cho We employed chemical hardness to explain the adsorption behaviour of Cr(VI) anions on metal oxide sorbents. In the absence of electrostatic attraction at pH values around the point of zero charge, silica and titania nanoparticles adsorbed a very small amount of Cr(VI) anions. This lack of adsorption is because the magnitude of the chemical hardness is too high to pair with the less hard Cr(VI) anions. In contrast, maghemite nanoparticles with relatively weak values of hardness ...

TRIZ-Based Approach for Accelerating Innovation in Chemical Engineering
The objective of this article is to demonstrate that, in fact, TRIZ-based methodologies are well-suited for the chemical industry by presenting (1) relevant statistics (almost 60% of all projects performed by our company over the last 8 years involved improving chemical or bio-chemical products and technologies), (2) specific TRIZ-based case studies from the fields of chemistry and chemical engineering and (3) general reasoning on the areas of chemical engineering in which TRIZ should be most effective.

Numerical analysis of dialysis with chemical reaction at steady state. Irreversible second order reaction
Publication date: Available online 26 July 2015 Source:Chemical Engineering and Processing: Process Intensification Author(s): Vojtěch Štěpánek, Zdeněk Palatý, Helena Bendová In the present work, the effect of chemical reaction on the rate of dialysis is analysed. The attention is paid to an irreversible second-order chemical reaction at steady state. A simple scheme, in which component A is transported through the membrane by diffusion and reacts with component B diffusing in the opposite direction, is considered. The analogy between the solution-diffusion model in the membrane transport and mass transfer in g...

The effect of chemical composition on the leaching behaviour of electric arc furnace (EAF) carbon steel slag during a standard leaching test
Publication date: Available online 26 September 2015 Source:Journal of Environmental Chemical Engineering Author(s): D. Mombelli, C. Mapelli, S. Barella, C. Di Cecca, G. Le Saout, E. Garcia-Diaz The electric arc furnace (EAF) slag could be exploited in several fields of application, such as land filling, road constructions and concrete production. However, their use is limited by the presence of polluting chemical elements (chromium (Cr), barium (Ba), Vanadium(V), etc.) that can be dangerous to humans and the environment. Thus, chemical and structural stability is a fundamental requirement, especially when the slag...

Implementation of chemical reaction equilibrium by Gibbs and Helmholtz energies in tubular reactor models: Application to the steam–methane reforming process
Publication date: 2 February 2016 Source:Chemical Engineering Science, Volume 140 Author(s): Jannike Solsvik, Tore Haug-Warberg, Hugo A. Jakobsen In the tubular reactor models the mass and heat source terms due to chemical reactions in the species mass balances and temperature equation are conventionally determined from kinetic rate expressions. In many cases a kinetic rate model is not available but the chemical equilibrium conversion can be determined from reaction equilibrium calculations minimizing the Gibbs or Helmholtz free energies. Although a process is believed to behave physically like a tubular reactor, pre...

Model reduction for stochastic chemical systems with abundant species
Biochemical processes typically involve many chemical species, some in abundance and some in low molecule numbers. We first identify the rate constant limits under which the concentrations of a given set of species will tend to infinity (the abundant species) while the concentrations of all other species remains constant (the non-abundant species). Subsequently, we prove that, in this limit, the fluctuations in the molecule numbers of non-abundant species are accurately described by a hybrid stochastic description consisting of a chemical master equation coupled to deterministic rate equations. This is a reduced descriptio...
