The method may include providing a nitrogen liquefaction unit and providing a natural gas liquefaction unit. Liquefaction of the nitrogen can be achieved via a nitrogen refrigeration cycle within the nitrogen liquefaction unit. Liquefaction of the natural gas can be achieved through the use of natural gas letdown and a second nitrogen refrigeration cycle. The two liquefaction units can be integrated via a common nitrogen recycle compressor, thereby providing significant capital savings.

摘要： This invention relates to a method for liquefying a gas containing at least 60 mol % of CO2, in order to produce at least one liquid product, wherein the gas is cooled in order to form a fluid flow, at least a portion of the liquid or supercritical flow is cooled in a heat exchanger in order to form a cycle fluid having a cycle pressure, the cycle fluid is divided into at least two fractions including an auxiliary fraction, one of the fractions being expanded up to a first pressure in a valve in order to form a biphasic mixture, and then sent to a phase separator. The liquid fraction of the phase separator is vaporized so as to form a vaporized gas in the exchanger, the vaporized gas then being expanded from the first pressure to a second pressure in an expansion means, and then compressed in the cycle compressor and mixed with the first feed gas.

摘要： A process for recovering ethane and heavier hydrocarbons from LNG and a hydrocarbon gas stream is disclosed. The LNG feed stream is divided into two portions. The first is supplied to a fractionation column as a first upper mid-column feed. The second portion is heated while condensing a portion of a column distillation stream, thereby producing a “lean” LNG stream and a reflux stream. The reflux stream is supplied as top column feed. The second portion of LNG feed is heated further and supplied to the column as a first lower mid-column feed. The gas stream is divided into two portions. The second is expanded, then both portions are cooled while vaporizing the lean LNG stream and heating another portion of the distillation stream. The colder first portion is supplied to the column as a second upper mid-column feed, and the second is supplied as a second lower mid-column feed.

摘要： A process for the recovery of heavier hydrocarbons from a liquefied natural gas (LNG) stream and a hydrocarbon gas stream is disclosed. The LNG feed stream is heated to vaporize at least part of it, then expanded and supplied to a fractionation column at a first mid-column feed position. The gas stream is expanded and cooled, then supplied to the column at a second mid-column feed position. A distillation vapor stream is withdrawn from the fractionation column below the mid-column feed positions and directed in heat exchange relation with the LNG feed stream, cooling the distillation vapor stream as it supplies at least part of the heating of the LNG feed stream. The distillation vapor stream is cooled sufficiently to condense at least a part of it, forming a condensed stream. At least a portion of the condensed stream is directed to the fractionation column as its top feed. A portion of the column overhead stream is also directed in heat exchange relation with the LNG feed stream, so that it also supplies at least part of the heating of the LNG feed stream as it is condensed to form a “lean” LNG stream. The quantities and temperatures of the feeds to the column are effective to maintain the column overhead temperature at a temperature whereby the major portion of the desired components is recovered in the bottom liquid product from the column.
