Propane to propylene reactor
Thread Content
When producing propylene from propane, I saw that UOP also uses a method with four reactors connected in series for operation. But I’m not sure whether these four reactors, just like the four reactors in the CCR process, also have increasing volume from front to back If so, how should the reactor volume be allocated among different reactors?
The four CCR reactors are connected in series from top to bottom within a single reactor vessel; they are radial reactors. The gas flows in from the upper part of the reactor, passes horizontally through the catalyst layer via fan-shaped tubes, then reaches the central tube, and exits from the lower part of the reactor. After being heated, it enters the next reactor. I wonder how the propylene production reactors from propane are connected in series? How does the gas flow?
The reactors used for producing propylene from propane are divided into fluidized bed and fixed bed types. The fluidized bed type is more stable and easier to operate, while the fixed bed type consists of those four reactors that are used alternately; once the catalyst becomes inactive, it is removed for regeneration, after which the reactor is switched to use one that has been regenerated. We use two reactors in rotation; they are of the same size.
