Impact of copper(II) on activation product removal from reactor decommissioning effluents in South Korea. Journal of Industrial and Engineering Chemistry, 82, 261-268. doi:10.1016/j.jiec.2019.10.022More infoDecommissioning is one of the most important phases in the life of a nuclear reactor, having a major influence on public perception of such technology. Therefore, development of technologies that make decommissioning more safe, effective and efficient is integral to the success of the nuclear industry. In this paper, phosphonic acid functionalised silica has been studied to determine its suitability for treating nuclear decommissioning effluents produced in the HYBRID process, developed in South Korea. Cu2+ recovery from HCl media in both static and dynamic modes was investigated, as well as the effect of Cu2+ on Co2+ and Ni2+ recovery in a column loading system. Isothermal loading studies predicted a maximum loading capacity for Cu2+ of 22.82 mg g-1, however complex loading behaviour was observed. Cu2+ sorption followed pseudo-second order kinetics with rapid uptake. Thermodynamic parameters have been extracted from collected kinetic data. Cu2+ outcompetes both Co2+ and Ni2+ for binding to the silica in column studies, which has implications for the use of phosphonic acid functionalised silica in treating decommissioning effluents. This work presents initial lab scale experiments, but shows the potential of Si based extractants for use in metals recovery in the nuclear industry.

Non-catalytic cracking of jojoba oil to produce fuel and chemical by-products. Industrial Crops and Products, 43(1), 386-392. doi:10.1016/j.indcrop.2012.07.042More infoAbstract Thermal non-catalytic cracking of jojoba oil, a non-triacylglyceride-based wax produced by the desert plant, Simmondsia chinensis, was compared to that of triacylglyceride-based soybean oil. Optimum liquid product yield was produced at a higher temperature for jojoba oil compared to soybean oil but at similar reaction pressure and residence time. At optimum conditions, jojoba oil generated a similar gas phase fraction as soybean oil while the liquid product contained a smaller quantity of undesirable polyaromatic and non-GC-elutable (low volatility high-MW) products, with nearly 90% of the cracking liquid product being GC quantifiable. This product included a mixture of linear saturated short-chain fatty acids whose size distribution peaked at C10. It also included alkanes (predominantly linear) that peaked at C7–C8, and smaller concentrations of alkenes, aromatics, and polyaromatic hydrocarbons. Thus, jojoba oil is an excellent renewable feedstock for the production of replacements for petroleum-derived transportation fuels and chemicals.

Optimization of Coal Particle Flow Patterns in Low N0x Burners. a. doi:10.2172/790986More infoIt is well understood that the stability of axial diffusion flames is dependent on the mixing behavior of the fuel and combustion air streams. Combustion aerodynamic texts typically describe flame stability and transitions from laminar diffusion flames to fully developed turbulent flames as a function of increasing jet velocity. Turbulent diffusion flame stability is greatly influenced by recirculation eddies that transport hot combustion gases back to the burner nozzle. This recirculation enhances mixing and heats the incoming gas streams. Models describing these recirculation eddies utilize conservation of momentum and mass assumptions. Increasing the mass flow rate of either fuel or combustion air increases both the jet velocity and momentum for a fixed burner configuration. Thus, differentiating between gas velocity and momentum is important when evaluating flame stability under various operating conditions. The research efforts described herein are part of an ongoing project directed at evaluating the effect of flame aerodynamics on NO{sub x} emissions from coal fired burners in a systematic manner. This research includes both experimental and modeling efforts being performed at the University of Arizona in collaboration with Purdue University. The objective of this effort is to develop rational design tools for optimizing low NO{sub x} burners. Experimental studies include both cold-and hot-flow evaluations of the following parameters: primary and secondary inlet air velocity, coal concentration in the primary air, coal particle size distribution and flame holder geometry. Hot-flow experiments will also evaluate the effect of wall temperature on burner performance.

Teamed Internships in Environmental Engineering and Technology: A Project Report
. Journal of Engineering Education, 89(2), 111-114. doi:10.1002/j.2168-9830.2000.tb00502.xMore infoThis paper is a summary report of the “Teamed Internships Program” (TIP), an Advanced Technological Education (ATE) grant through the National Science Foundation (NSF). This three-year project created internships encompassing regional industries, federal research facilities, and two- and four-year educational institutions. The project cultivated teamwork and communication skills for environmental technician and engineering students, developed instructional materials, and provided valuable contacts with industry. To foster faculty and teacher enhancement and student interest in environmental science and technology, insights from the program were incorporated into instructional materials and educational modules for dissemination to local secondary schools. - Ogden, G.

Remediation of low-level mixed waste: cellulose-based materials and plutonium
. Journal of Hazardous Materials, 51(1-3), 115-130. doi:10.1016/s0304-3894(96)01798-0More infoLow-level mixed radioactive wastes containing cellulose-based materials and plutonium have been generated during various nuclear processing activities. Biological digestion of the organic- or cellulose- based material was examined as an environmentally acceptable and effective method of treatment for these and other similar wastes. Cellulase enzyme was used to initiate biodegradation prior to 90% destruction of the cellulose material by a sewage sludge consortium. Plutonium did not significantly effect the biodegradation. Bench-scale experimental data were used to design a batch treatment system. A cost and sensitivity analysis was performed to determine the optimal reactor size, materials of construction and media type. The sensitivity analysis indicated that while a 12-month treatment scenario using a carbon steel ball mill, sludge digester and vacuum thickener was the least expensive scenario evaluated on a levelized cost basis ($800 per ton of waste degraded per month), the 12-month scenario using stainless steel construction and the alternative dewatering system offered the most cost-effective treatment alternative and better corrosion resistance (levelized cost of $1130 per ton per month). The dewatering system consisting of a disk centrifuge and sludge dryer is capable of doubling the sludge solids content and produce an overall waste reduction of 67%. The proposed waste treatment system offers a cost savings of up to 31% compared to conventional disposal practices. - Ogden, G. E., & Davis, R. H. (1990). EXPERIMENTAL DETERMINATION OF THE PERMEABILITY AND RELATIVE VISCOSITY FOR FINE LATEXES AND YEAST SUSPENSIONS. Chemical Engineering Communications, 91(1), 11-28. doi:10.1080/00986449008940698More infoThe specific cake resistances of thin layers of fine latexes and of yeast cells have been determined from flux data for pressure drops of up to 100 kPa in a static filtration device. A single correlation has been developed that relates the cake resistance to particle diameter for monodisperse rigid latex spheres with diameters between 1.0 and 6.7 μm. The specific resistance of the yeast cell layers was found to be almost 50 times larger than that of the rigid latex spheres of the same median diameter The relative viscosities of a 7.3 μm latex and yeast cell suspensions have been measured in a cone-and-plate viscometer. Empirical correlations relating the relative viscosity to the solids volume fraction were developed from linear regression of the data for each suspension. A correlation was also developed that relates the relative viscosity of the yeast cell suspension to the cell count. The effective shear-viscosities were not observed to exhibit a significant shear-rate dependence. However, an apparent v...

In a.More infoThe proposed research is directed at evaluating the effect of flame aerodynamics on NO{sub x} emissions from coal fired burners in a systematic manner. This fundamental research includes both experimental and modeling efforts being performed at the University of Arizona in collaboration with Purdue University. The objective of this effort is to develop rational design tools for optimizing low NO{sub x} burners to the kinetic emissions limit (below 0.2 lb./MMBTU). Experimental studies include both cold and hot flow evaluations of the following parameters: flame holder geometry, secondary air swirl, primary and secondary inlet air velocity, coal concentration in the primary air and coal particle size distribution. Hot flow experiments will also evaluate the effect of wall temperature on burner performance. Cold flow studies will be conducted with surrogate particles as well as pulverized coal. The cold flow furnace will be similar in size and geometry to the hot-flow furnace but will be designed to use a laser Doppler velocimeter/phase Doppler particle size analyzer. The results of these studies will be used to predict particle trajectories in the hot-flow furnace as well as to estimate the effect of flame holder geometry on furnace flow field. The hot-flow experiments will be conducted in a novel near-flame down-flow pulverized coal furnace. The furnace will be equipped with externally heated walls. Both reactors will be sized to minimize wall effects on particle flow fields. The cold-flow results will be compared with Fluent computation fluid dynamics model predictions and correlated with the hot-flow results with the overall goal of providing insight for novel low NO{sub x} burner geometry's.
