| 摘要 |
An improved process for the vaporization of liquid hydrocarbon feeds wherein high boiling components present in the liquid feed are removed from the feed prior to subsequent processing comprising heating the liquid feed to a temperature at, but just below, its dew point, introducing the thus heated feed into a separation zone where any high boiling liquid components are removed and removing a substantially dry gaseous feed from the separation zone. The process minimizes fouling in heat exchangers and other indirect heating systems caused by coking of entrained high boiling liquids in the vaporized feed.
