A B S T R A C T EXTRACTION PROCESS AND APPARATUS Extraction process comprising the following steps: (i) contacting a feed (e.g. a heavy hydrocarbon oil) with an extractant (e.g. propane and/or butane) in an extraction zone, (ii) removing a product (e.g. asphalt) from a lower part of the extraction zone, (iii) heating at least part of a fluid removed from an upper part of the extraction zone, (iv) separating heated fluid in a separation zone into fluids of different density, and (v) introducing at least part of a fluid of higher density into the upper part of the extraction zone. The invention further relates to an extraction apparatus comprising a housing having feed- and extractant-inlet means, first product outlet means in its lower end part (e.g. comprising a settling section and mixing means for feed and extractant) and in its upper end part fluid outlet means communicating via heat exchange means with a settling vessel having in its upper section second product outlet means and in its lower section reflux outlet means communicating with the upper end part of the housing.
