Abstract
The technological and heat engineering substantiation for a new process arrangement for nepheline production using the sintering process is presented. In this process desilication of aluminate liquor and evaporation of a soda liquor is combined in one stage. As a result the thermodynamic performance (exergic efficiency) increased from 70 to 90% and the steam requirement decreases 1.6 together with improvements in operational reliability of equipment.
