PROCESS FOR SOLVENT ADDITION TO HIGH VISCOSITY BITUMEN FROTH

摘要

A process for treating a high viscosity bitumen-containing stream, which includes contacting the high viscosity bitumen-containing stream with a solvent- containing stream having a lower viscosity in a pipeline reactor having interior pipe walls, such that the solvent-containing stream is present between the interior pipe walls and the bitumen-containing stream during initial mixing between the high viscosity bitumen-containing stream with a solvent-containing stream; mixing the high viscosity bitumen- containing stream with a solvent-containing stream sufficiently to produce an in-line flow of a solvent diluted material; supplying the solvent diluted material into a separation vessel; and withdrawing high diluted bitumen and solvent diluted tailing components from the separation vessel.
