Zusammenfassung:	Processes to separate a light hydrocarbon stream comprising ethylene, ethane, and C3+ hydrocarbons into an ethylene stream, an ethane stream, and a C3+ hydrocarbon stream, including: feeding the light hydrocarbon stream to a deethanizer; separating the light hydrocarbons in the deethanizer to form a C3+ hydrocarbon bottoms stream and a C2-rich overhead stream comprising ethylene and ethane; separating the C2-rich stream in a C2-rectifier to form a first ethylene stream and an ethane-rich bottoms stream; and separating the ethane-rich bottoms stream in a C2-splitter to form a second ethylene stream and an ethane stream.
