This integrated plant mainly comprises a gas fractionation plant and an MTBE production part.
The gas fractionation plant processes cracked gas generated by the catalytic cracking unit by adopting a mature three-tower process flow and selecting an ADV micro-dispersion tray.
The MTBE plant produces MTBE (Methyl Tertiary Butyl Ether) products for adjusting octane ＆#118alue of gasoline by using mixed C4 and methanol produced by the gas fractionation plant as the raw materials based on a mixed-phase bed-catalytic distillation combined process.
Main products: propylene (purity not less than 99), propane, mixed C4 and MTBE.
