METHOD OF TREATING A HYDROCARBON STREAM COMPRISING METHANE, AND AN APPARATUS THEREFOR |
摘要 |
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. |
