Catalytic cracking unit shutdown top circulation system

When the catalytic cracking unit is shut down, the oil from the top circulation system is usually sent to other related units or storage facilities for processing. The specific methods of handling may vary depending on the different processes and equipment designs. Common treatment methods include the following: 1. Storage: Storing the oil from the top circulation system in specialized tanks, and reintroducing it into the system once the device is restarted. 2. Reuse: Send the oil from the top circulation system to other related units for processing, such as naphtha units or reforming units. 3. Incineration: The oil from the top cycle system is fed into an incinerator for combustion, thereby minimizing its impact on the environment. Regardless of the approach adopted, it is necessary to ensure safe operations and comply with relevant regulations and environmental protection requirements. At the same time, depending on the duration of the shutdown and the properties of the oil, certain testing and cleaning tasks may also be required to ensure normal operation of the facility once it is restarted. .
