Naphtha Hydrotreating Process
Naphtha Hydrotreating is an essential step for refiners to produce cleaner gasoline from different feedstocks : straight run, condensate, cracked naphtha feedstocks (coker, VB, cracked catalytic naphtha).
The Naphtha Hydrotreating process is also important to pretreat naphtha for downstream units, like paraffin isomerization and catalytic reforming, where severe specifications are required and catalysts used are very sensitive to impurities. The objective is to reduce sulfur and nitrogen contents (less than 0.5 weight ppm), but also olefins (less than 0.1 weight percent).
