Is the so-called pre-distillation in an ethylene plant the quenching section? Experts, please explain; I don’t quite understand!

The pyrolysis gas exiting the pyrolyzer unit is cooled to between 200 and 300 degrees through a waste heat boiler and quench oil, and then cooled to room temperature in a quench water tower. The heavy components in the pyrolysis gas (fuel oil, pyrolysis gasoline, moisture) are separated and sent to the compression unit.
