Description
Technical Field
The utility model relates to a chemical production's oil refining technical field discloses a delayed coking coke cooling water treatment facilities.
Background
The delayed coking unit is one of the most widely used heavy oil lightening processes at present and is one of the important means for heavy oil deep processing in oil refineries. When the coke tower of the delayed coking device finishes the water drainage of the cold coke, a small part of oil sludge, coke powder and coke blocks enter the cold coke water buffer tank together with the cold coke water, and a part of dissipated steam overflows from a tank top breather valve when the high-temperature cold coke water enters the tank, so that the environment is influenced. In addition, some oil sludge, coke powder and coke blocks can be deposited in the coke cooling water buffer tank and the coke cooling water storage tank, and can only be cleaned before the device is overhauled or the normal operation of the coke cooling water system is seriously influenced, so that the stability of the coke cooling water system is influenced. The hazardous waste treatment of the oil sludge consumes a large amount of economic cost and pollutes the environment.
In recent years, in order to reduce the entering of coke blocks into a coke cooling water tank during water discharging, a water discharging filter is added on a water discharging pipeline of a coke tower in part of processes, a valve is arranged below the filter, and blocky petroleum coke accumulated in the filter is swept into a coke pool through steam. Under the process, although the filter effectively prevents the blocky petroleum coke from entering the cold coke water tank, the filter cannot prevent oil sludge and coke powder, and the cold coke water still contains a certain amount of oil sludge and coke powder. The oil sludge and the coke powder still abrade the pipeline, and particularly under certain environments, the coke cooling water is corrosive. The abrasion of the pipeline is increased under the combined action of the abrasion and the corrosion, and the stability and the safety of the pipeline are reduced; coke powder particles in the coke cooling water are locally accumulated in a pipeline and equipment, so that the logistics is not smooth, and the normal operation is influenced.
On the other hand, the oil sludge contains heavy oil components with certain recycling value, so that the sludge can be recycled in advance and recycled, long-period operation of equipment and pipelines can be guaranteed, and certain economic value is created while the generation of dangerous waste is reduced.
