ABSTRACT:
An improved dual fractionating process for hydrocarbons which employs a high pressure and a low pressure fractionating zone, light ends from the low pressure fractionating zone being introduced into the high pressure fractionating zone, heavy ends from the high pressure fractionating zone being introduced into the low pressure fractionating zone, the improvement being characterized by the introduction into one of the fractionating zones of a stable hydrocarbon stream, the hydrocarbon stream being stable under the conditions existing in the high pressure fractionating zone, at least a portion of the hydrocarbon stream having a boiling point lower than the boiling point of at least one of the unstable components which accumulates in the high pressure fractionating zone.
