PROCESS OF PRODUCING FUEL FRACTIONS Russian patent published in 2006 - IPC C10G7/00 

FIELD: liquid fuel production processes.

SUBSTANCE: invention relates to production of fuel fractions by preliminarily preparing and processing hydrocarbon feedstock: petroleum, gas condensate, and petroleum-gas condensate mixtures. Process comprises mixing petroleum with gas condensate followed by processing mixtures. Depending on plant operation conditions and normalized properties of desired fuel fraction, secondary and primary components of hydrocarbon mixtures are combined in amounts found from following formula: where G_s denotes amount of secondary mixture stream, kg/h; G_p amount of primary mixture stream, kg/h; x_i,p potential portion of desired fraction of primary mixture stream; x_i,s potential portion of desired fraction of secondary mixture stream; ρ_n normalized density of petroleum product and ρ_p and ρ_s densities of desired fractions of primary and secondary petroleum products, respectively, kg/m³; ν_n normalized viscosity of petroleum product and ν_p and ν_s viscosities of desired fractions of primary and secondary petroleum products, respectively, m²/s·10^-6; T_fn normalized freezing temperature of petroleum product and T_fp and T_fs freezing temperatures of desired fractions of primary and secondary petroleum products, respectively, K. Thus formed petroleum-gas condensate mixture stream is then processed.

EFFECT: improved quality and increased yields of fuel fractions relative to their potential in feedstock.
