Co-located riser catalytic cracking and coaxial catalytic cracking
Thread Content
What are the main principles and differences between the vertical stacked riser catalytic cracking process and the coaxial catalytic cracking process?
Coaxial: It offers good degassing performance, is simple to operate, suitable for small FCC units, and has relatively low energy consumption. % j! {2 S6 h: \3 I( l* [9 R Side-by-side high and low: capable of processing low-quality raw materials, slow catalyst deactivation, high reagent-to-oil ratio, empirical data, higher liquid yield ratio on a coaxial basis
