Active coke regeneration mixed vapor treatment method and apparatus

A method for treatment of a mixed vapor in an active coke regeneration, the method comprising the following process steps of:

• A) performing a first water condensation on a mixed vapor, produced during an active coke regeneration process, by spray water in a first condensation zone located in a first structure;
• B) performing a second water condensation on the mixed vapor, after the first water condensation, by spray water in a second condensation zone located in a second structure separate from the first structure, to further condense and purify the mixed vapor, wherein a flow velocity of the mixed vapor within the second condensation zone is controlled at a range of 0.5-1.5 m/s to achieve a sufficient contact time for water vapor and active coke micro powder in the mixed vapor and spray water;
• C) eliminating moisture in a gas fraction of the mixed vapor trough mist elimination in a gas-water separation zone located in the second structure after the second condensation zone, and then discharging the gas from an upper portion of the second structure, wherein a flow velocity of the gas is controlled in a range of 3-5 m/s such that the moisture in the gas is completely eliminated during the mist elimination;
• and
• D) discharging condensation water together with active coke micro powder removed from the mixed vapor, in the first structure and in the second structure.
