RELATIVE MODEL OF CRUDE OIL COMPATIBLENESS Russian patent published in 2008 - IPC G01N33/22 G01N33/28 C10G1/00 

FIELD: chemistry; organic.

SUBSTANCE: number of inventions relate to possibility of blending two or more liquid hydrocarbons or different types of crude oil. Method of evaluation of dissolving capacity of one or several liquid hydrocarbons includes: (a) determination of distillation tracing and density of each liquid hydrocarbon; (b) digital integration of distillation tracing of each liquid hydrocarbon and getting of average volumetric boiling point for each liquid hydrocarbon; (c) calculation of characteristics factor K for each liquid hydrocarbon using average volumetric boiling point which is received in the procedure from the ratio ; (d) determination of dissolving capacity of each liquid hydrocarbon using characteristics factor K which is received in the procedure (c) from the ratio in which VAPB - average volumetric boiling point, SG - specific gravity of oil. Definition method of critical dissolving capacity of liquid hydrocarbons, method of blending at a minimum two liquid hydrocarbons; method of blending at a minimum two different types of crude oil and crude oil blend are also presented. The quality of predicting improves.

EFFECT: forecast quality enhancement of possibility to blend two or more liquid hydrocarbons or different types of crude oil.
