A wet hydrocarbon stream having 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 In a water removal device a wet disposal stream having water is withdrawn from the wet hydrocarbon stream, at the second temperature. An effluent stream having the wet hydrocarbon stream from which the wet disposal stream has been removed, is discharged from the water removal device and passed to a further heat exchanger. A refrigerant stream is also passed to the further heat exchanger, and both the effluent stream and the refrigerant stream are cooled in the further heat exchanger by indirect heat exchanging against an evaporating refrigerant fraction. The effluent stream is heated by indirectly heat exchanging against the wet hydrocarbon stream. The cooling of the wet hydrocarbon stream includes this indirectly heat exchanging.

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

A method for receiving fluid from a natural gas pipeline, the fluid comprising gaseous hydrocarbons, liquid hydrocarbons, water and optionally solids, the method comprising: (a) in a slug catcher (), receiving the fluid comprising gaseous hydrocarbons, liquid hydrocarbons, water and optionally solids from at least one pipeline () (b) in the slug catcher (), separating at least a portion of the gaseous hydrocarbons from the rest of the fluid to leave a liquid mixture or a liquid/solid mixture; (c) directing at least a portion of the liquid mixture or liquid/solid mixture to a separation vessel (), preferably a three-phase separation vessel; and (d) in the event of a surge of liquids and optionally solids to the slug catcher (), directing at least a portion of the liquid mixture or the liquid/solid mixture from the slug catcher () to a surge vessel ().
