What is the PetroFCC Process? RxCat and PetroFCC Benefits: Enhanced catalytic cracking – Increased propylene yield Reduced thermal cracking – Decreased dry gas yield Catalyst selection flexibility – Choice of catalyst supply – Optimized for feedstock and product objectives RxCat Technology UOP 4399A-11 . 5 19 14 Naphtha 28 14 7 5 Aromatics BTX 18 Distillate Fuel Oil Coke 9.5 5 5.Typical PetroFCC Process Yield.5 UOP 4399A-12 .5 11 C2C3’s C4’s C3= 24 C4= 53. wt-% (VGO Feed) Traditional FCC PetroFCC Process C2= 9 Light Olefins 6 22 3 6.

What is MTO? Gas to Olefins (GTO) Natural Gas Synthesis Gas Production Methanol Methanol Synthesis MTO Ethylene & Propylene Coal Coal to Olefins (CTO) UOP 4399A-17 . UOP/HYDRO MTO Process Reactor Regenerator Quench Tower Regen Gas High selectivity to light olefins Ethylene & Propylene Oxygenate Recovery Light Olefin Recovery – Minimizes feedstock costs – High value product mix with little C5+ co-product – Little hydrogen & methane Air Water Flexibility of C2=/C3= product ratios Water Methanol UOP 4399a-18 . Why MTO? 100% 80% 60% 40% 20% Naphtha Cracker MTO ge nta a Adv O MT Product values generally increase with crude oil prices Naphtha cracker feedstock prices are closely linked to crude oil prices – High feedstock costs offset most of the economic benefits as product values increase ROI MTO feedstock is from dedicated sources using cost advantaged feedstock – Fixed price not tied to crude oil – Can support increased methanol prices when olefin values are higher (high crude oil prices) MTO is competitive with steam crackers when crude oil is above $16 per barrel – Huge advantage when crude oil prices are high UOP 4399A-19 0% 10 20 30 40 50 Crude Oil Benchmark. $/BBL .
