20090095018 | METHOD FOR LIQUEFYING A HYDROCARBON STREAM - A hydrocarbon stream is liquefied in a method wherein a feed stream is provided, from which feed stream a first stream and a second stream are produced. The first stream is liquefied in a main liquefaction system to provide a first liquefied stream, while the second stream is cooled separately to provide a cooled second stream. The first liquefied stream is combined with the cooled second stream to produce a combined stream, which is separated in a gas/liquid separator into a liquefied hydrocarbon product stream and a gaseous stream. The gaseous stream is warmed to a temperature of above −40° C. by heat exchanging against any other stream used in the method, wherein the warming of the gaseous stream employs at least heat exchanging against the second stream to provide at least part of the cooling of the second stream. | 04-16-2009 |

20110239701 | METHOD OF REJECTING NITROGEN FROM A HYDROCARBON STREAM TO PROVIDE A FUEL GAS STREAM AND AN APPARATUS THEREFOR - Method of, and apparatus for, rejecting nitrogen from a hydrocarbon stream to provide a fuel gas stream. A hydrocarbon stream is at least partially liquefied and subsequently expanded. The expanded hydrocarbon stream is fractionated in a fractionation column to provide an nitrogen-rich hydrocarbon stream and a nitrogen-lean hydrocarbon stream. The nitrogen-rich hydrocarbon stream is partially condensed in a condenser by cooling against a refrigerant circulated in a dedicated first refrigerant circuit, and phase-separated to provide a nitrogen-rejection stream and a nitrogen-lean reflux stream which is returned to the fractionation column. The nitrogen-lean hydrocarbon stream is partially vaporized and phase-separated to provide a vapour stream that is returned to the fractionation column and a liquefied nitrogen-lean hydrocarbon stream that is subjected to sub-cooling. The fuel gas stream is generated from the sub-cooled nitrogen-lean hydrocarbon stream. | 10-06-2011 |
