[54] METHOD AND APPARATUS FOR SEPARATION HYDROCARBON STREAMS
[57] Abstract: A condensed mixed hydrocarbon feed stream (10), recovered from an initial feed stream (8), is fractionated into one ore more fractionated streams. In this process, the condensed mixed hydrocarbon feed stream (10) is separated into at least a first part-feed stream (20) and a second part-feed stream (30). The first part- feed stream (20) is passed into a first gas/liquid separator (14), to provide at least a first fractionated stream in the form of a first gaseous overhead stream (40). A first bottom liquid stream (50) provided by the first gas/liquid separator (14) is passed into a second gas/liquid separator (22) to provide at least a second fractionated stream in the form of a second gaseous overhead stream (70), which is cooled by heat exchange (26) against the second part-feed stream (30).
