Solvent dehydration and separation of native asphalt
A combined process for dehydration, deasphalting, and acetone fractionation of Ashal'chinsk native asphalt was developed and investigated. Technology was proposed for combined solvent preparation and separation of natural asphalt and the basic characteristics of the process were determined. The technical and economic indexes of the proposed and traditional technologies were compared.
