METHOD OF CONTROLLING PROCESS OF THERMAL DESTRUCTION OF PETROLEUM RESIDUES IN PIPE FURNACE Russian patent published in 2008 - IPC C10B55/00 G01N33/22 G05D27/00 

FIELD: petroleum processing.

SUBSTANCE: method according to invention determines pressure gradients at exit and entrance in each section of the furnace and real gradient is compared to projected gradient, after which, depending on disagreement value, this value is diminished via variation of fuel consumption in corresponding furnace burner. Projected gradient is calculated using formula: ΔPi=k(L1+b)n, wherein ΔPi is pressure gradient in i-th section of coil, %; k, b, n are coefficients depending on conversion value, nature of raw material, and projected quality of final thermal destruction products; and L1 reduced length of coil from its beginning to i-th measurement point, %.

EFFECT: decreased coking of furnace coil and increased operation cycle of plant, which incorporates the furnace.
