Abstract (en)
[origin: EP0711966A2] In the generation of an ethane-rich fraction for use as make-up in the cooling circuit in a process for liquefying a hydrocarbon-rich fraction, a side-stream of the already liquefied hydrocarbon fraction is fed to a C1/C2/C3+ fractionating column. An ethane-rich fraction is drawn off from the middle of the fractionating column and mixed with the ethane-bearing cooling medium.
