Bayer Process Heat Exchangers Cleaning Efficiency: Optimizing the Acid Dissolution of Sodalite Scale
Aluminum metal is produced by the electrolytic reduction of aluminum oxide (Al2O3), mainly extracted from bauxite ore digested in a hot caustic soda solution. This solution is supersaturated with respect to sodium aluminate and silicate, which react together to form sodalite (3[Na2O⋅Al2O3⋅2SiO2⋅2H2O]⋅Na2CO3) at high temperatures. Heat exchanger tubes are scaled with this compound, which serious...
متن کاملCrystallization of hard aspherical particles.
We use numerical simulations to study the crystallization of monodisperse systems of hard aspherical particles. We find that particle shape and crystallizability can be easily related to each other when particles are characterized in terms of two simple and experimentally accessible order parameters: one based on the particle surface-to-volume ratio and the other on the angular distribution of ...
متن کاملCollisions of small ice particles under microgravity conditions
Context. Planetisimals are thought to be formed from the solid material of a protoplanetary disk by a process of dust aggregation. It is not known how growth proceeds to kilometre sizes, but it has been proposed that water ice beyond the snowline might affect this
متن کاملMorphology of Ruthenium Particles for Methanation under Reactive Conditions
The potential of hydrogen as a future energy carrier is only fully unleashed if fuel processors generating hydrogen of a suitable purity can be engineered. Selective methanation of CO can be used as a first step for cleaning up feed gas for e.g. proton exchange membrane (PEM) fuel cells [1] where CO poisons the platinum electrodes and for removing oxygen containing compounds in hydrogen feeds u...
متن کاملCluster-induced crystallization of nano-silicon particles
The possibility of producing from 20 nm to 100 nm sized silicon powders by plasma-induced reactions of silane including the formation of high-mass hydrogenated silicon anion clusters has been recently demonstrated. Careful HREM imaging showed circular contrast features, 1.5 to 2.5 nm in size, embedded in the amorphous particles which was attributed to the presence of medium range order in these...
