Power-driven vapor compression apparatus for use during e.g. dehydratation of ethanol by permeation, has isolating and connecting device for isolating and connecting dehydratation unit to vaporized hydrated substrate

摘要

The apparatus has an exchanger (F) for vaporizing hydrated volatile compounds using heating sections (Fa, Fv). Exchangers (Cv, Er) respectively condensate the excess amount of dehydrated vapor, and pre-heat the liquid supplied to a dehydratation installation. Main control-regulation chains (FC, LC, PC) respectively control a supply rate, a liquid level in a base of the exchanger (F), and pressure of the installation. An isolating and connecting device (Rs) isolates and connects a dehydratation unit (UD) to a vaporized hydrated substrate. An independent claim is also included for a method for implementing a power-driven vapor compression apparatus.
