A wet hydrocarbon stream (510) comprising at least methane and water, provided at a temperature equal to a first temperature, is cooled thereby lowering the temperature to a second temperature. In a water removal device (525) at least one wet disposal stream (590) comprising water is withdrawn from the wet hydrocarbon stream, at the second temperature. An effluent stream (560), comprising the wet hydrocarbon stream from which the at least one wet disposal stream (590) has been removed, is discharged from the water removal device (525) and passed to a further heat exchanger (535). At least one refrigerant stream (210) is also passed to the further heat exchanger (535), and both the effluent stream (560) and the refrigerant stream (210) are cooled in the further heat exchanger (535) by indirect heat exchanging against an evaporating refrigerant fraction (230). The effluent stream (560) is heated by indirectly heat exchanging against the wet hydrocarbon stream (510), wherein said cooling of the wet hydrocarbon stream (510) comprises this indirectly heat exchanging.
