This is a classification of refining processes and the types of refinery products, shown by a flow chart. The flow chart starts with crude oil. Above crude oil chemical constitution is written and below physical properties are written. Crude oil leads to the refining process including separation, conversion, finishing and support.

Stability and flow testing are described in test methods ASTM D6927/ AASHTO T 245. The compacted asphalt specimen is conditioned in a water bath before being placed in a Marshall breaking head. The breaking head and specimen assembly are positioned in a Marshall stability tester outfitted with components to measure stability and flow during …

Figure 3.8.1. Solvent Deasphalting Process Flow Diagram • One facility reported using propane and phenol solvents for deasphalting residuum. The DAO is sent to lube oil processing and the asphalt fraction is sent to delayed coking or fuel oil blending. During process upsets, heavy hydrocarbons may become entrained in the solvent

Hot mix asphalt (HMA) paving materials are a mixture of size-graded, high quality aggregate (which can include reclaimed asphalt pavement [RAP]), and liquid asphalt cement, which is heated and mixed in measured quantities to produce HMA. Aggregate and RAP (if used) constitute over 92 percent by weight of the total mixture.

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 …
