In such a case, what is the purpose of installing a pressure relief device?

The current equipment configuration is as follows: 1.5 million tons of atmospheric distillation, 800,000 tons of catalytic processing, followed by units for gas separation, hydrogenation, and others! Catalysis is the main secondary processing method. The properties of the crude oil are as follows: its density is around 0.86, and its residue content is about 3%. The atmospheric distillation yield ranges from 40% to 50%; other parameters are not listed here Given the above circumstances, let’s discuss the significance of adding vacuum distillation
Based on the current yield, and assuming no change in the properties of the crude oil, with the existing facilities in place, it is possible to consider omitting the depressurization system and feeding the crude residue directly into the catalytic unit. What needs to be considered primarily is whether the existing catalysts can be used to process residue oil, the cost of modifications required for this purpose, the cost of installing a vacuum distillation system, as well as factors such as the benefits generated and the investment payback period. Based solely on the above indicators, the following opinion can be given; it is impossible to determine anything else if there are other issues.
Thank you, the catalyst was designed based on RFCC!
1.5 million tons of atmospheric distillation – 800,000 tons of catalytic process; it’s not easy to meet the demand, right?
Purchased raw materials. In the past, we used a vacuum distillation process with a pressure of 200, and a catalytic process with a pressure of 100; most of the raw materials used were purchased
We were more or less in the same situation before. Now the distillation unit is larger, while the catalytic unit is smaller; it cannot handle full-load production, so the distillation unit has to operate at a reduced load. :lol
You can sell the paraffin oil, right?:lol
