Abstract
This invention provides for the separation of an amine composition undergoing processing at high temperatures and pressures which amine composition contains volatile components and less volatile components where the volatile components are desirable for further processing and/or utilization and the less volatile components are less desirable for further processing and/or utilization. The separation serves to divide the amine composition into two streams, one which is enriched in the volatile components and the other which is enriched in the less volatile components.
Claims6
A process for the treatment of organic amine compositions which are under such temperature and pressure that with time at least a portion of the components thereof can undergo molecular chemical change and which can change desirable components and undesirable components, the desirable component being more volatile than the undesirable component, which process comprises arresting such molecular chemical change by subjecting such amine composition to a component separation at a pressure and temperature at which such more volatile component becomes, during separation, a supercritical fluid and the amine composition is converted into a multi-phase system, forming from such separation two enriched streams, one which is more enriched in the more volatile amine components of such amine composition than is such amine composition, and the other of which is less rich in such more volatile amine components than is said other stream and such amine composition but more enriched in the less volatile components of the amine composition than is said other stream and the amine composition.
