Abstract: [cze] [eng]
V rámci výzkumu a vývoje technologie výroby vysoce čistého krystalického síranu amonno-hlinitého byly provedeny pokusy s krystalizací síranu hlinitoamonného z roztoku v poloprovozním měřítku (objem roztoku 50 litrů) a stanovena distribuce kontaminantů (Na, K, Fe, Si, Ca, Cr, Mg, Ti, Ga, Mn, Zn, Co, Pb a Cu) mezi krystalickou fází a roztokem. Dále byla vyhodnocena tepelná bilance krystalizace. The report deals with research and development of the process for production of extra pure ammonium aluminium sulphate by crystallization from solution. In the pilot plant, the crystallization experiments were carried out with the solution volume of 50 litres. The distribution of contaminants (Na, K, Fe, Si, Ca, Cr, Mg, Ti, Ga, Mn, Zn, Co, Pb a Cu) between the crystalline phase and solution was determined. The heat balance of the crystallization process was evaluated.
