To enhance the efficiency of water usage in this unit, the plant replaces fresh water with wastewater from the air-cooled softening water that was previously discharged into the circulating water system, resulting in a reduction in fresh water consumption from 20 tons per hour to 8 tons per hour. **The fresh water used in the 10,000-ton delayed coking unit is primarily intended for replenishing the water used in desulfurization processes within the unit. Due to insufficient depth of this water supply, after thorough evaluation, some existing pipelines were utilized to connect the purified water from the two acid production units to the flue gas coking unit, thereby enabling the reuse of wastewater through process optimization. Once this project is implemented, the unit will no longer need to rely on fresh water.
