METHOD FOR CONTROLLING PROCESS OF HIGH-TEMPERATURE HEATING OF HEAVY OIL RESIDUES IN TUBE FURNACE Russian patent published in 1997 - IPC

FIELD: petroleum processing. SUBSTANCE: fuel is fed in amount in accordance with following inequalities: where K(T,τ), K*L

, K*u, respectively, are current, permissible lower and permissible upper limiting values of coefficients of heat transfer from reaction mixture to inner surface of coil pipeline; T_R(τ), T*R,l, T*R,u, respectively, are current, permissible, lower and permissible upper limiting values of reaction mixture temperature; and τ is time. EFFECT: optimized operation conditions. 2 dwg
