Title:
METHOD AND FOR TREATING MATERIAL MIXTURE POSSESSING AT LEAST TWO PHASES HAVING DIFFERENT BOILING TEMPERATURES APPARATUS THEREFOR
Document Type and Number:
Japanese Patent JPH09176751
Kind Code:
A
Abstract:

To provide a method for surely separating components respectively having different boiling temps. from each other advantageous in terms of cost and safely to environment to same the energy without requiring inert scavenging gases, gaseous fuel and combustion air.

A material mixture is treated under a starting pressure of <100 millibar and in a temp. range where only the phase at least mainly having the low boiling temp. is evaporated under intermittent measurement of the temp. in the material mixture in the absence of oxygen. The evaporated phase is condensed in a condenser K1 and is gathered to a shieldable vessel B1. The vessel B1 is shielded from the condenser K1 when the temp. transition in the material mixture is charged by the removal of the phase having the lower boiling temp. The material mixture is further treated at the further increased temp. to evaporate and condenser at least one kind of the heavy metals from the group of cadmium and mercury.
