AI Technical Summary

Problems solved by technology

For example, heavy hydrocarbon crude oil and natural bitumen are difficult to handle because their low gravity and high viscosity hinder their ability to flow in vessels or refinery streams
Additionally, heavy hydrocarbons can accumulate over time in various refinery process streams, contaminate system outlets, or require costly process downtime

Abstract

Apparatuses and systems for removing heavy hydrocarbons from a solvent stream are disclosed herein. The apparatuses extract heavy hydrocarbons into light hydrocarbons and provide a solvent stream having the heavy hydrocarbons removed. Two water washing steps are used to remove residual solvent from the heavy hydrocarbon solution in light hydrocarbons. In some embodiments, the second water wash is used for processing subsequent batches of the solvent stream. The heavy hydrocarbons and solvent can be recovered and processed further. Methods for removing heavy hydrocarbons from a solvent stream are also disclosed herein.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application 61 / 121,153, filed December 9, 2008, which is hereby incorporated by reference in its entirety. [0003] Statement Regarding Federally Funded Research [0004] Not applicable. Background of the invention [0005] Heavy hydrocarbons such as bitumen, kerogen, GILSONTTE (trade name for mineral hard pitch) and tar are high molecular weight hydrocarbons commonly found in the petroleum industry. These heavy hydrocarbons vary in state from viscous liquids to solids at ambient temperatures and are generally difficult to recover in useful forms. For example, heavy hydrocarbon crude oils and natural bitumen are difficult to handle because their low gravity and high viscosity hinder their ability to flow in vessels or refinery streams. Additionally, heavy hydrocarbons can accumulate over time in various process streams in a refinery, contaminate system outlet...
