<p><P>PROBLEM TO BE SOLVED: To provide a vapor anhydration method of a hydrated organic substance which is widely applicable, user-friendly, highly economical and highly energy-saving by boosting the compression pressure of vapor as an anhydrated product and elevating the condensation temperature to reuse the vapor as the evaporation heat of a supply liquid. <P>SOLUTION: In the anhydrization method of the hydrated organic substance as a liquid raw material by the steam permeation membrane separation method, the method comprises steps of boosting the pressure of the anhydrated organic substance vapor which comes out from the membrane module by a compressor to elevate the condensation temperature of the vapor, then sending the same to an evaporator, and recovering and reusing the condensation latent heat. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
