Title:
METHOD FOR RECOVERING COMPONENT OF SOLUTION, DEVICE FOR RECOVERING COMPONENT OF SOLUTION, AND SYSTEM FOR IMPREGNATION AND FOR RECOVERING IMPREGNANT
Document Type and Number:
WIPO Patent Application WO/2010/140423
Kind Code:
A1
Abstract:
A device (40) for recovering a solution is disclosed in which a solution comprising an impregnant that undergoes a solidification reaction in the absence of oxygen at temperatures not lower than a given solidification temperature and a solvent containing the impregnant dissolved therein is introduced into a separation part (41). Air (oxygen) is supplied to the solution introduced into the separation part (41), and the pressure of the internal space of the separation part (41) is reduced. The temperature of the solution is regulated with a heat exchanger (43) so as to be in a given separation temperature range below the given solidification temperature, while stirring the solution with a stirrer (42), and the solvent contained in the solution is vaporized. The vaporized solvent is cooled with and recovered in a main water recovery part (51) and a secondary water recovery part (61). Thus, the impregnant is prevented from solidifying by reducing the pressure at a temperature within the given separation temperature range while supplying oxygen and by separating the impregnant from the solvent.
