Solvent de-asphalter



A solvent de-asphalter is a unit in a crude oil refinery that separates the asphalt from the processing crude oil using the fact that light hydrocarbons will solve the remainder of the crude oil, but not the asphaltens in the crude. The output from the de-asphalter unit is de-asphalted oil, DAO and asphalt. If the solvent is butane the unit will be referred to as a butane de-asphalter, BDA and in the solvent is propane, it will be called a propane de-asphalter, PDA unit.
