Liq. mixture thermal separation method - heating re-concentrating solvent stream and mixture stream before combining at end for supply

摘要

The mixture is pumped (5) to a preheater (3) for liquefaction and then passed to an absorber (4) along with a recycled part stream of solvent from a desorber (1) is enriched in mixture enrichment section (41m 42) without mutual mixing to the smae concn. and temp. with the evaporating component. A neutral gas stream from the liquefier and several neutral gas streams from the desorber with different contents of the evaporating component are fed to equal vapour pressure locations of the enrichment section against the absorbing liquid streams. In the first part (41) the re-concentrating solvent stream is heated and in the second part it heats the mixture stream. The liquid streams combine at the end for supply to the desorber. USE/ADVANTAGE - Galvanic cell, thermoelectric cell. Energy requirements are less than current processes.
