Solvent deasphalting (SDA) is one of the most interesting bottom-to-barrel technologies as economic solution for the processing of heavy oils and residues. The Pörner subsidiary EDL offers a process that extracts heavy residues (vacuum, visbreaker, hydrocracker residues, heavy used oil, refinery residues (bunker oil), FCC residues (heavy recycle oil)) by means of solvents, such as propane, and split into DAO (deasphalted oil) and a pitch (asphalt). Fuel refineries can process the DAO, e.g. in hydrocrackers, FCC and refining plants to become gasoline, diesel or fuel oil components. Lube refineries use the DAO as bright stock for the production of lube oils.

 

Unique combination

The Pörner Group as a specialist for residue processing and bitumen technology provides advice, design and development of complete technology concepts for an ideally hundred per cent non-residue refinery. A Solvent Deasphalting (SDA) plant combined with a Biturox® Bitumen plant is capable of processing various heavy residues entirely to become valuable products, such as DAO (Deasphalted Oil) and Bitumen.

 

A secure beginning

At company-owned pilot plants in Germany and Austria and in cooperation with research institutes an optimized plant design is ultimately defined. The client thus gets detailed data on the efficiency and economic feasibility of the investment giving him planning security.
