Catalytic settler coking removal

Here, there are dedicated people responsible for cleaning the coke

The coking removal work here is carried out by us ourselves, and the following points should be taken into account during the operation: 1. Safety comes first; one must wait until the temperature of the settler has dropped before entering. First, it is necessary to hire a professional construction team to set up scaffolding inside the settler. 2. Pay attention to dust prevention – appropriate protective equipment must be worn when entering to avoid inhaling coke powder and catalyst powder into the lungs. 3. Safety belts must be worn at all times while working, and when carrying out cross-tasking, one must be careful of oneself and others to prevent unnecessary injuries

It depends on the degree of coking inside your settler. If there is little coking, the method described on the third floor can be used; if the coking is severe, it’s necessary to hire a professional team to remove it, otherwise maintenance work will be delayed. When there is a lot of coking, it becomes difficult to lower the temperature, and opening the maintenance cover can lead to the burning of the coked material, thereby damaging the internal components. In cases of severe coking, it’s necessary to enlist the help of military engineers to carry out explosive removal, as this cannot be done by oneself.

We carry out the coking work by ourselves; as the refinery workers say, we also hire construction teams to set up the scaffolding, but everything else is done by us

We hired a professional coking removal team to hydraulically clean the coke from the oil and gas pipelines up to the fractionation tower section. The coke inside the settler is removed by the company’s internal coke removal personnel using non-hydraulic methods. In addition to paying attention to safety, it is necessary to clear the coke so that the equipment itself (the lining) can be seen. Prevent coke from falling after startup, which could cause blockages in the flap valves or fluctuations in the fluidization of the inclined tubes.

We all hired external construction teams to do the work; I’ve also heard that blasting is used, but I’ve never seen it. It should be less strenuous, right?

We all organize the cleaning ourselves, but we need to pay attention to the following points: 1. It is necessary to lower the temperature and ensure sufficient ventilation time (usually 24 hours). 2. Flammable gas analysis and oxygen level analysis must be conducted before entry, and the relevant procedures must be followed. 3. Hire professionals to set up the scaffolding. 4. Take proper personal protective measures (mainly to prevent dust; we usually wear dust masks and coveralls, fasten safety belts, and use adequate lighting). 5. Before entering, use rods at the equipment openings and manholes to strike the centrifuge and material legs, so that any loose coke pieces fall off first and do not cause injury upon entry. 6. When cleaning the coke, start from the top down, and make sure to keep a distance between each other. It is crucial for those who are conscientious to keep track of the coking condition in the settler, analyze the causes of coking, and strive to make improvements in order to reduce coking! ! ! After all, cleaning the furnace isn’t a good job; it’s dirty. . . . . . . Tired. . . . . . Moreover, it is also extremely detrimental to the long-term operation of the device!

These days, no one does the task of cleaning coke by themselves; instead, they hire contractors for it. Cleaning coke is a dirty, strenuous, and dangerous job – who would want to do it? I remember that in the first few years I was at the factory, we did it ourselves; others would feed us and take care of our needs, but that was over a decade ago.

You’re really lucky; we have to do the coke cleaning by ourselves every time, and it’s really.................... Once, when we went in to clean it, we saw that the coke lumps at the bottom were still smoking

We also clean the coke by ourselves, in agreement with what was said on the 3rd floor and the 8th floor.
