PROCEDURE AND INSTALLATION FOR PROCESSING TAR SAND Russian patent published in 2011 - IPC C10G1/04 

FIELD: oil and gas production.

SUBSTANCE: invention refers to procedure for processing tar sand. The procedure consists in crumbling source raw material, in extraction by means of its contact with an organic solvent in an extractor, in division of produced mixture into liquid and solid phases, in dividing liquid phase producing a target product - bitumen and regenerated solvent, in solid phase contact drying, in successive return of regenerated solvent into process and in withdrawal of dried solid phase. The distinguished features of the procedure are like follows: contacting in the extractor is carried out in a suspended state of crumbled tar sand in organic solvent. Successively produced suspended medium is supplied to centrifuging where liquid and solid phases are divided. Also, process of extraction is cyclic, while centrifuging is carried out continuously. Liquid phase is divided into the target product-bitumen and regenerated solvent by two-stage evaporation. At the second stage a diesel fraction is rectified. Dried solid phase of sand is directed to briquetting with binding. The invention also refers to the installation of tar sand processing.

EFFECT: production of target product - bitumen meeting standards for road bitumen, diesel fraction as commodity product and building material as artificial gravel.
