Solvent deasphalting – Petroleum Refinery,Petroleum ...

Solvent deasphalting is a petroleum refining process for processing heavy oil. The process uses heavy oil such as vacuum residue as raw material, and extracts hydrocarbons such as propane and butane as solvent. The extract is deasphalted oil. It can be used as a heavy lubricating oil raw material or a cracking raw material, and the raffinate deoiled asphalt can be used for road asphalt or ...

Deasphalting Process. Figure 5.8 places the deasphalting process in a refinery flow scheme as an intermediate process between vacuum distillation and dewaxing processes, for producing the refinery output streams as asphalt deasphalted oil (DAO), which can be directed to another separation process, dewaxing, to produce lubricating oil base stock and wax,or can be sent to conversion units such ...

Deasphalting FSC 432: Petroleum Refining

Because of the low H/C ratio of asphaltenes and resins, the deasphalting process can be considered as a “carbon rejection” process, yielding a high H/C ratio product (i.e., oil) after removing the asphaltenes and resins, as, typically, lower value byproducts. Figure 5.5. Solvent fractionation of

Petroleum processing normally involves separation into various fractions that require further processing in order to produce marketable products. To separate the higher molecular weight and higher boiling fractions from crude, special processing steps must be used. The first application of solvent extraction in refining was the recovery of heavy lube oil base stocks by propane (C3H8) deasphalting.
