ABSTRACT:
In a process for thermally cracking a low-quality feed stock containing a considerable proportion of heavy fractions such as high-boiling fractions, and evaporation residual oil, and a system used therefor, in which the low-quality feed stock is withdrawn from the preheater of the thermal cracking furnace to separate and remove a required proportion of said heavy fractions and thereafter returned to subject the feed stock to further preheating and thermal cracking. The low-quality feed stock thermally cracked has a predetermined proportion of the heavy fractions removed, and coking in the thermal cracking system at various lines is avoided from occurring.
