Asphaltenes removal from heavy feeds

Hydrotreating processes have two definite roles (1) desulfurization to supply low-sulfur fuel oils and (2) pretreatment of feed residua for residuum fluid catalytic cracking processes. The main goal is to remove sulfur, metal, and asphaltene contents from residua and other heavy feedstocks to a desired level. 

Solvent deasphalting Solvent-enhanced precipitation process to remove asphaltenes from heavy lube base stocks and for improving the feed quality of catalytic cracker feed.
