摘要： Processes and systems for stabilizing the operation of a steam cracker primary fractionator. In some embodiments, the process can include (I) feeding a first steam cracker effluent into a steam cracker primary fractionator. The process can also include (II) feeding a make-up liquid stream into the steam cracker primary fractionator. The process can also include (III) recovering a steam cracker gas oil (“SCGO”) side stream from the steam cracker primary fractionator. The process can also include (IV) recovering a steam cracker tar (“SCT”) stream from a location at and/or in the vicinity of a bottom of the primary fractionator. The make-up liquid stream can include a first hydrocarbon portion and a second hydrocarbon portion. The first hydrocarbon portion can be distributed into the SCGO side stream. The second hydrocarbon portion can be distributed into the SCT stream.
