Deasphalting Process | FSC 432: Petroleum Refining

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 ...

The game of refining is making sure the right molecules end up in the right conversion unit to maximize the value of every hydrocarbon processed. To that end, the solvent deasphalter [de-asphalter] (SDA) unit is a deceptively simple process that effectively makes the split between a relatively light product, deasphalted oil (DAO), and a heavy product, pitch. The ‘clean’ DAO can then be ...

The output– de-asphalted oil (often referred to as DAO) and asphalt– is then used for lube oil feedstock, vacuum gas oil (VGO), resid hyrocracking (RHC), conversion feedstock, and as feedstock to hydrocrackers, delayed coking and fluid catalytic cracking units. Its varied uses are dependant on the quality of the resulting DAO.
