Title: Refining developments/Review of ways to upgrade resid(ua)

Journal Article · · Hydrocarbon Process.; (United States)
OSTI ID:6163204

When selecting the best process for reduced crude oils, the basic problem is how to handle the asphaltene fraction at reasonable cost, either by conversion to an oil (IA) or, by removal and indirect conversion, to a gas or steam (IB), or by concentrating the asphaltenes into a useful product (II). As the trend to use poorer quality crudes increases, prior treatments such as residual hydrodesulfurization, will become predominant among Type IA processes (which also include H-Oil and L-C fining). For IB-type processes, there will be a trend toward partial oxidation of the asphaltenes, rather than steam-reforming of the increasingly more valuable naphtha and gas fractions, to provide the hydrogen needed for hydrodesulfurization. When considering Type II processes, visbreaking is limited, solvent deasphalting better reduces the amount of product into which the asphaltenes are concentrated, and delayed coking is the best. If no residual product is desired, heavy oil cracking, Type IB, would be preferable to Type II processes, and would also provide steam. Some properties of the products obtainable from Taching, Light Arabian, and Lloydminster crudes are discussed.
