Abstract

The present application is concerned with processes and apparatuses for the separation of nitrogen from liquefied natural gas feeds. The processes comprise the steps of: (i) cooling the feed and passing the feed to a fractionation column; (ii) withdrawing from the fractionation column an overhead vapour stream having an enriched nitrogen content, and a liquid stream having a reduced nitrogen content; (iii) dividing the overhead vapour stream from step (ii) into at least first and second overhead streams; (iv) compressing, cooling and at least partially condensing at least the first overhead stream from step (iii); and (v) expanding the stream from step (iv) and passing the expanded stream to the fractionation column as reflux, and wherein cooling in step (iv) is provided, at least in part, by heat exchange with one or more streams from the fractionation column.
