The temperature and pressure of the catalytic reaction are normal, but the oil slurry system and the intermediate section system of the distillation tower are unstable; the temperature of the baffle plates in the distillation tower as well as the temperature of the material returning to the tower in the intermediate section fluctuate greatly. What could be the reasons for this? How to solve it
In the second year of the second cycle, the first cycle operates for 5 years
First, contact the dispatch team to analyze and determine whether there have been significant changes in the composition and properties of the crude oil. Additionally, changes in the catalyst’s activity and selectivity can also affect the product distribution. If there are no issues with these two elements, then analyze whether the temperatures and flow rates of the reflux streams at various stages of the distillation system are normal, and simultaneously check whether there are any changes in the materials entering the facility from outside.
First, you need to determine whether the fluctuations are caused by Unit 1 or by the slurry system. This is easy to judge. Large changes in Zone 1 can lead to changes at the top of the fractionation tower; if it is the slurry that causes large changes in Zone 1
