Beschreibung
Zusammenfassung:	An integrated process for producing lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. The sour feed can be delivered to a catalytic dewaxing step without any separation of sulfur and nitrogen contaminants, or a high pressure separation can be used to partially eliminate contaminants.
