Process for removing polymer-forming impurities from naphtha fraction
Patent
·
OSTI ID:864818
- Pittsburgh, PA
- Avonmore, PA
Polymer precursor materials are vaporized without polymerization or are removed from a raw naphtha fraction by passing the raw naphtha to a vaporization zone (24) and vaporizing the naphtha in the presence of a wash oil while stripping with hot hydrogen to prevent polymer deposits in the equipment.
