PCA and neural networks-based soft sensing strategy with application in sodium aluminate solution
Component concentration of sodium aluminate solution is an important quality index for alumina production. In this article, we propose a new on-line soft sensing strategy for measuring component concentration of sodium aluminate solution. With this method, on-line control can be realised in aluminate production plants. Several advance techniques are used, such as principal component analysis (P...
متن کاملTheoretical studies on aluminate and sodium aluminate species in models for aqueous solution: Al(OH)3, Al(OH)4, and NaAl(OH)4
Ab initio quantum mechanical calculations were performed on Al(OH)3, Al(OH)4, NaAl(OH)4 and related species with varying numbers of explicit water molecules to elucidate the structural, spectral and energetic properties of the possible species. We find that Al(OH)3 reacts with H2O in the gas-phase with an exoergicity of 24.1 kcal/mol to produce Al(OH)3H2O, which has shorter Al-OH distances, lar...
متن کاملOne-part geopolymer mixes from geothermal silica and sodium aluminate
At present, the most commonly used building material is ordinary Portland cement (OPC). However, OPC has a negative environmental effect during synthesis, with the release of significant amount of CO2 greenhouse gas. The cement industry is responsible for 5-8% of total global anthropogenic CO2 emissions. Geopolymerization is a technology capable of turning industrial wastes into strong and chem...
متن کاملSynthesis and Characterization of γ-Alumina Porous Nanoparticles from Sodium Aluminate Liquor with Two Different Surfactants
Among the various phases of alumina, two phases γ and α are the most widely used in variousindustries. In this paper, γ-Al2O3 porous nanoparticles have been successfully synthesized from a s...
متن کاملThermodynamic Modeling and Experimental Studies of Bayerite Precipitation from Aluminate Solution: Temperature and pH Effect
Bayerite is one of the phases of aluminum hydroxide which is precipitated by the carbonation of aluminate solutions obtained from sintered nepheline syenite leaching. In this study, the conditions for the bayerite formation were predicted by thermodynamic modeling of the carbonation process and the Bromley- Zemaitis model was used for this purpose. Carbonation experiments were carried out a...
