PROCESS FOR REMOVING NITROGEN FROM A HYDROCARBON-RICH FRACTION CONTAINING NITROGEN COMPRISES COMPRESSING A PARTIAL STREAM OF A PREVIOUSLY HEATED NITROGEN-RICH FRACTION, COOLING, CONDENSING, AND MIXING WITH A NITROGEN-RICH FEED.

摘要

Process for removing nitrogen from a hydrocarbon-rich fraction comprises temporarily and/or depending on the nitrogen content of the hydrocarbon-rich fraction compressing a partial stream of a previously heated nitrogen-rich fraction, cooling, condensing, mixing with the nitrogen-rich feed obtained in the nitrogen removal process, and feeding as reflux to the nitrogen removal process. Process for removing nitrogen from a hydrocarbon-rich fraction (1) containing nitrogen comprises temporarily and/or depending on the nitrogen content of the hydrocarbon-rich fraction compressing a partial stream (30) of a previously heated nitrogen-rich fraction (15), cooling, condensing, mixing with the nitrogen-rich feed obtained in the nitrogen removal process, and feeding as reflux to the nitrogen removal process.
