FIELD: oil and gas industry.
SUBSTANCE: this invention relates to a coking unit under fluidised conditions, which has a reaction tank with a steaming section including horizontally located partitions of the steaming section, to which steam is sprayed to blow off occluded hydrocarbons from a coke product; with that, these partitions of the steaming section are located in the steaming section horizontally in the form of tiers located at some distance from each other vertically, in each of which partitions are arranged parallel to each other. The partitions arranged into pairs of tiers located in the steaming section in positions following one after another in a vertical direction are turned at an angle relative to the partitions in the pair of tiers located nearby, and each partition of the steaming section has a cross section in the form of a perforated chute open from the bottom, having a top facing in an upward direction and ending to external edges in a downward direction.
EFFECT: proposed unit allows reducing formation of deposits and carryover of hydrocarbons.
