Abstract
FIELD: chemical engineering. SUBSTANCE: method is performed by way of pumping bauxite slurry through autoclave installation containing the following units. Slurry-slurry heat-exchangers providing two-step heating in different heat-exchangers when using, as heat carrier in the 1st heating step, leached slurry from the 2nd-step separator and, as that in the 2nd heating step, leached slurry from the 1st-step separator. Vapor-slurry heat exchangers (heat carrier: self- evaporation vapor from 1st-step separator). Heating and reaction autoclaves. 1st-step separator. 2nd-step separator conveying self- evaporation vapor to heat process water. Agitator for leached slurry. In the process, leached slurry in the 1st-step heating heat exchangers is cooled to a temperature higher than boiling temperature of slurry in the 2nd step of self evaporation. Leached slurry in the 2nd-step heat exchangers is cooled to a temperature lower than its boiling temperature under atmosphere pressure, which prevents steaming and outburst of alkali vapors from agitator. EFFECT: increased utilization of heat of leached slurry. 1 dwg
