The Neural Network House: An Overview

A process and apparatus for obtaining crystals of a particular substance from a flowing solution thereof, by supplying the seeding crystals to one nth portion of the saturated solution and supplying one nth portion of the solution to the crystalliser further downstream at each of (n-1) places. The supersaturation of the solution is maintained at the required value by keeping the static pressure so low that self-vaporisation occurs, whereas this static pressure is caused to drop gradually in the crystalliser from its inlet end toward its discharge end.
