INTEGRATION OF SOLVENT DEASPHALTING AND GASIFICATION

The invention is the integration of a process of gasifying asphaltenes in a gasification zone by partial oxidation and the process of asphaltene extraction with a solvent. The integration allows low level heat from the gasification reaction to be utilized in the recovery of solvent that was used to...

Beschreibung
Zusammenfassung:	The invention is the integration of a process of gasifying asphaltenes in a gasification zone by partial oxidation and the process of asphaltene extraction with a solvent. The integration allows low level heat from the gasification reaction to be utilized in the recovery of solvent that was used to extract asphaltenes from an asphaltene-containing hydrocarbon material. Asphaltenes are extracted from an asphaltene-containing hydrocarbon material by mixing a solvent in quantities sufficient to precipitate at least a fraction of the asphaltenes. The precipitated asphaltenes are then gasified in a gasification zone to synthesis gas. The gasification process is very exothermic. The low level heat in the synthesis gas, either directly, or via an intermediate step of low pressure steam, is used to remove and recover the solvent from the deasphalted hydrocarbon material and from the asphaltenes prior to gasification.
