Embodiment Construction

[0016]In the following detailed description section, the specific embodiments of the present disclosure are described in connection with preferred embodiments. However, to the extent that the following description is specific to a particular embodiment or a particular use of the present disclosure, this is intended to be for exemplary purposes only and simply provides a description of the exemplary embodiments. Accordingly, the disclosure is not limited to the specific embodiments described below, but rather, it includes all alternatives, modifications, and equivalents falling within the true spirit and scope of the appended claims.

[0017]The term “asphaltenes” as used herein refers to hydrocarbons which are the n-heptane insoluble, toluene soluble component of a carbonaceous material such as crude oil, bitumen or coal. One practical test to determine if oil is an asphaltene is to test whether the oil is soluble when blended with 40 volumes of toluene but insoluble when the oil is bl...

Abstract

The invention relates to improved bitumen recovery processes and systems. The process may include providing a bitumen froth feed stream, separating the stream in a froth separation unit to produce a diluted bitumen stream, treating the diluted bitumen stream in an electrostatic desalter to produce a treated bitumen stream, and separating the treated bitumen stream into a solvent recycle stream and a bitumen product stream. The system may include a combined AC / DC desalter with a control unit for optimizing the treatment process to produce a product bitumen stream using less solvent and smaller separators than conventional bitumen froth treatment plants and processes.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is a divisional application of U.S. application Ser. No. 12 / 464,724, entitled OPTIMIZING HEAVY OIL RECOVERY PROCESSES USING ELECTROSTATIC DESALTERS, filed on May 12, 2009, which claims the benefit of U.S. Provisional Application No. 61 / 133,270, filed Jun. 27, 2008.FIELD OF THE INVENTION[0002]The present invention relates generally to producing hydrocarbons. More specifically, the invention relates to methods and systems for upgrading bitumen in a solvent based froth treatment process using electrostatic desalting for optimization of the process.BACKGROUND OF THE INVENTION[0003]The economic recovery and utilization of heavy hydrocarbons, including bitumen, is one of the world's toughest energy challenges. The demand for heavy crudes such as those extracted from oil sands has increased significantly in order to replace the dwindling reserves of conventional crude. These heavy hydrocarbons, however, are typically located in g...
