Catalytic start-up time for heavy oil
Thread Content
Apart from the long initial startup time, catalytic cracking generally takes a short amount of time. Our company usually maintains a temperature of 150 degrees for 2 hours from the start of heating, then keeps the temperature at 350 degrees for another 2 hours to carry out heat tightening, after which the temperature is raised to 550 degrees. The material is then fluidized and fed in; 8 hours later, everything is ready! I wonder what the advantages and disadvantages are?
From ignition to maintaining a temperature of 150 degrees for 2 hours, then to maintaining a temperature of 350 degrees for 2 hours for heat consolidation, followed by raising the temperature to 550 degrees; the material I is fluidized, and feeding continues for 8 hours. Driving in this way causes significant damage to the linings of the two components; if you don’t believe it, check the linings after one cycle of driving.
What you are doing is wrong. Every time the catalytic unit is overhauled, the linings of the two vessel systems need to be repaired. If the heating rate is too fast, it will cause the repaired lining to peel off or similar issues ； At the same time, the internal components of the two devices will become deformed and damaged due to excessive temperature rise. A certain catalytic unit once completed steps such as heating up, loading the catalyst, and injecting fuel within 24 hours, yet the unit only operated for less than a month.
Happy New Year. :victory:
Rapid startup is a common problem among domestic enterprises; many managers use this as a criterion to assess the performance of workshops. In fact, the startup speed should be increased on a scientific basis, and certain necessary heating processes and times must be ensured – otherwise, it reduces the service life of the linings and is not conducive to the long-term operation of the equipment. There is no doubt that the benefits brought about by a longer duration far outweigh those of starting operations a few hours earlier; therefore, please hold firm under pressure and think things through carefully
I’ve seen fierce ones before, but I’ve never seen anything this fierce. It’s extremely strong and powerful
Which catalytic cracking unit is this? We need to learn from it – it’s that impressive?
Thank you, I’ve learned something. We just stopped; we haven’t started yet
Operating procedures are, in essence, the result of experience and lessons learned from mistakes; going against the laws of production and seeking quick results will only lead to problems.
In fact, it’s sufficient to check the specifications for the lining. To ensure quality, standards are generally set on a conservative level, but this has a significant impact on the long-term operation of the two devices
