FIELD: oil refining processes; warming-up retarded coking reactors.
SUBSTANCE: proposed method of warming-up empty reactor includes delivery of primary cooling product removed from reactor being cooled at initial stage of cooling the coke with water followed by delivery of distillate vapor from operating reactor. Then, hydrocarbon condensate is discharged to warming-up reservoir and vapor phase from this reservoir is discharged to purse reservoir or to rectifying column. Liquid phase is pumped-out to substandard petroleum product line. It is good practice to perform initial stage of cooling the coke with water for 1-2 h. Vapor flow from reactor being cooled is fed in the downward direction to reactor to be warmed-up.
EFFECT: reduced power requirements due to avoidance of use of water vapor; reduced toxic effluents.
