Treatment With Plural Parallel Cracking Stages Only TRIZ Cases
- HSFCC Reactor Feed Split for FCC Heat Balance
Heavy and light feed are split across four FCC reaction zones to balance catalyst heat and avoid supplemental fuel or catalyst coolers.
- Catalytic Cracking of Distillate Fractions for Higher Olefin and BTX Yield
Splitting raw oil into light and heavy distillates enables staged catalytic cracking that raises olefin and BTX yield while limiting dry gas and coke.
