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.
