Why didn't this graduation project pass?
Isn’t it generally calculated based on 8,000 hours?
[Ten years of major development in chemical technology] 216-2023 The world's largest dilute ethylene dry gas to ethylbenzene plant was successfully started up in one go https://bbs.hcbbs.com/thread-4799413-1-1.html (Source: Haichuan Chemical Forum Network)
Design generally takes 7,000 hours, which is 10 months. someone asked: Do you have 2 months of vacation left? No, the remaining 2 months will be considered as unplanned parking and maintenance period.
If this happens, the instructor should be given a failing grade and no common sense knowledge should be taught to the students.
Generally, the design time is 8,000 hours, and some owners will choose 8,400 hours.
Depending on the maturity of the process, the design does not take as long as the owner chooses.
study* Yes, the electricity consumption of our 24-hour equipment is calculated based on 8,000 hours per year.
Generally, designs are designed according to 8000 hours or 8400 hours.

Petrochemical Industry SH/T 3121-2022, Annual Operating Hours and Design Load 4.1 In addition to process restrictions, the designed annual operating hours of the refining unit should not be less than 8400h, and the designed annual operating hours of the chemical plant should not be less than 8000h. 4.2 The normal design load of the device should be designed in accordance with the device scale stipulated in the approval document. The lower limit of its operating elasticity can be 60% of the design load. The upper limit of the hydraulic elasticity of the entire device should not be higher than 110% of the design load. For devices with special requirements, the operating flexibility of the device can be adjusted as needed. There are also 7,000 hours and 7,200 hours (300 days).
