METHOD FOR IMPROVING HEAVY HYDROCARBON MIXTURE QUALITY Russian patent published in 2017 - IPC C10G45/00 C10G47/00 C10G9/00 F17D1/17 C10G49/00 C10G7/00 

FIELD: chemistry.

SUBSTANCE: method comprises: (1) separating the said heavy hydrocarbon mixture into, at least, the first part and the second part. The said first part contains 10-45 wt % of the heavy hydrocarbon mixture, and the said second part contains 90-55 wt % of the heavy hydrocarbon mixture; (2) thermal improving the said first part of the heavy hydrocarbon mixture in an upgrader to produce a light hydrocarbon mixture; (3) mixing the said light hydrocarbon mixture with the heavy hydrocarbon mixture to produce an improved hydrocarbon mixture. At the input to the said upgrader, the composition of the said first part of the heavy hydrocarbon mixture is identical to that of the said second part of the heavy hydrocarbon mixture, and the light hydrocarbon mixture produced by improvement is not subjected to separation before mixing with the said second part of the heavy hydrocarbon mixture. Thus, the heavy hydrocarbon mixture recovered from the well can be improved to lighter petroleum fractions.

EFFECT: improving the heavy hydrocarbon mixture quality.
