Abstract
A solution component recovery method, a solution component recovery apparatus, and an impregnation process/impregnation component recovery system for separating a first component from a second component. The separation between the first and second components is accomplished by reducing the pressure on a solution that contains the first component, which results in the solidification of the first component in the solution at a temperature that is equal to or higher than a predetermined solidification temperature. The second component, in which the first component is dissolved, is evaporated at a temperature range that is less than the predetermined solidification temperature. The evaporated second component is then recovered by a cooling step.
