Abstract
Power is generated in an organic Rankine cycle turbine by expanding a stream of solvent vapor produced by a flash drum in a deasphalting unit to produce a stream of expanded solvent vapor that is combined with a stream of solvent vapor and steam from a stripper of the deasphalting unit. Heat is extracted from the combined stream by an organic fluid that is vaporized and supplied to a Rankine cycle organic vapor turbine that produces power and expanded organic vapor. The solvent is recovered from the cooled, combined stream and re-used in the deasphalting unit. Heat extracted from products of the deasphalting unit vaporizes an organic fluid that is expanded in an organic vapor turbine that generates power.
