What impact does the kinematic viscosity of residue have on the operation of catalytic cracking units and on the yield of products?
This is a very big and complex issue; I’m just here to take a look~~~ Since it involves blending, I think the amount involved won’t be very large. There will definitely be some impact, but it probably won’t be significant. Be careful about regenerative charring and external heat extraction. With slag reducer added, there might be more heavy components, which could affect the yield of diesel. I’m still in doubt; I’ll wait and see what the other experts say below.
The slag produced by our previous processing caused the entire oil discharge slurry system to get clogged, resulting in huge losses
