Abstract
An apparatus and process are provided for cracking hydrocarbons. Hot, cracked effluent is removed to a quench header where it is pre-quenched with an oil containing crackable components, e.g., 1000° F.(538° C.) boiling range bottoms taken from a vapor/liquid separator, cracking the bottoms to more valuable products, e.g., steam crack naphtha. The overhead of the separator is fed to a cracker, and then quenched with a quenching oil.
