Abstract
Official abstract text for this publication.
A process for operating multiple oil sand mine sites for extracting bitumen from oil sand is disclosed, comprising preparing a first conditioned oil sand slurry at a first location using a first oil sand slurry preparation and slurry conditioning process; preparing a second conditioned oil sand slurry at a second location using a second oil sand slurry preparation and slurry conditioning process; combining the first conditioned oil sand slurry and the second conditioned oil sand slurry in at least one slurry distributor to produce a combined oil sand slurry; and distributing the combined oil sand slurry to at least one separation vessel to produce bitumen froth.
First claim
Opening claim text (preview).
We claim: 1. A process for operating multiple oil sand mine sites for extracting bitumen from oil sand, comprising: (a) preparing a first conditioned oil sand slurry at a first mine site using a first slurry preparation and conditioning process and subjecting the first conditioned oil sand slurry to a first bitumen separation process to produce a first bitumen froth; (b) preparing a second conditioned oil sand slurry at a second mine site using a second slurry preparation and conditioning process and subjecting the second conditioned oil sand slurry to a second bitumen separation process to produce a second bitumen froth; (c) combining the first bitumen froth and the second bitumen froth in at least one froth storage tank to produce a combined bitumen froth; and (d) subjecting the combined bitumen froth to further treatment to reduce the solids and water content therein. 2. The process as claimed in claim 1 , wherein the first bitumen froth and the second bitumen froth are deaerated prior to combining them in the at least one froth storage tank. 3. The process as claimed in claim 1 , wherein the first bitumen froth is heated prior to combining it with the second bitumen froth. 4. The process as claimed in claim 1 , wherein the first mine site is remote from the second mine site and the first bitumen froth is transported to the second mine site by means of a froth pipeline. 5. The process as claimed in claim 1 , wherein the further treatment comprises naphthenic froth treatment to produce naphtha diluted bitumen.
