The largest catalytic unit in the country
Thread Content
According to reports, Huizhou’s largest catalytic unit has a capacity of 4.8 million tons. Do you know anything about this? Let me share some information
Do you know what new processes they have adopted and what their energy consumption is?
It seems to be 450, Zhongke 420; some reports exaggerate the figure.
Now, more large-scale catalytic units are being put into operation one after another. As everyone knows, those catalytic units with a capacity of over 3 million tons are located in which refineries?
Lanzhou Petrochemical: 3 million per unit and 1.4 million per unit; Dalian Petrochemical: 3.5 million per unit, 1.2 million per unit, and 800,000 per unit; Hainan Refining & Chemical: 3.2 million
Adopting SEI design, with two-stage regeneration
The catalytic route has gradually become obsolete. Currently, residue hydrogenation and coking are generally the core of secondary conversion; even with catalysis, its role is not very significant. For a refinery with a capacity of 20 million tons, 3.5 million tons of catalyst should be sufficient. Catalyst size scaling up to 350 is about right
I agree with your view. The chemical processing route will inevitably become the mainstream; increasing the severity of catalysis in order to boost the production of olefins, particularly propylene, is the direction in which catalytic technology is evolving – that is, DCC catalytic cracking
