A method and apparatus for cooling a hydrocarbon stream such as natural gas. An initial hydrocarbon stream is passed through a first separator to provide an initial overhead stream and a mixed hydrocarbon feed stream. The initial overhead stream is cooled to provide a cooled hydrocarbon stream such as LNG, and at least a C1 overhead stream and one or more C2, C3 and C4 overhead streams are separated from the mixed hydrocarbon feed stream. At least a fraction of at least one of the group comprising: the C2 overhead stream, the C3 overhead stream and the C4 overhead stream is cooled with the C1 overhead stream to provide a cooled stream, which is further cooled against at least a fraction of the cooled, preferably liquefied, hydrocarbon stream to provide an at least partly liquefied cooled stream.

Method and apparatus for cooling a hydrocarbon stream

In a method and apparatus for treating a hydrocarbon stream having methane, at least a part of the hydrocarbon stream and a main refrigerant stream are cooled by indirect heat exchanging against a pre-cooling refrigerant. The pre-cooled hydrocarbon stream is passed to a first inlet of an extraction column, and an effluent stream is discharged from the extraction column. The effluent stream and at least a part of the pre-cooled main refrigerant stream are passed to a further heat exchanger, where they are both cooled thereby providing a cooled methane-enriched hydrocarbon stream and at least one cooled main refrigerant stream. The passing of the effluent stream to the further heat exchanger and the passing of the pre-cooled hydrocarbon stream to the first inlet of the extraction column includes indirectly heat exchanging the effluent stream against the pre-cooled hydrocarbon stream.

Method of treating a hydrocarbon stream comprising methane, and an apparatus therefor

A method of treating a hydrocarbon stream such as natural gas comprising at least the steps of: (a) providing a hydrocarbon feed stream (); (b) passing the feed stream () through a first separation vessel () to provide a first gaseous stream () and a first liquid stream (); (c) passing the first gaseous stream () from step (b) through a high pressure separation vessel () to provide a second gaseous stream () and a second liquid stream (); (d) maintaining the pressure of the first gaseous stream () between step (b) and step (c) within +10 bar; (e) passing the first liquid stream () of step (b) through a stabilizer column () to provide a third gaseous stream () and a stabilized condensate (); and (f) feeding the second liquid stream () from step (c) into the stabilizer column ().
