Abstract:

The 2.2 MM TPY FCC unit processing heavy oil of Russian crude oil of PetroChina Liaoyang Petrochemical Company adopts MIP-CGP technology(clean gasoline production technology for increasing propylene and producing more isomers) for renovation, using the dedicated catalyst CGP-LY. The calibration results show that under 100% production load conditions, compared with the FCC technology before the transformation, the yield of LPG remains basically unchanged after transformation by the MIP-CGP technology; the yield of propylene increases by 0.3 percentage points; the yield of gasoline increases by 5.47 percentage points, the RON is 92.23, with an increase of 1.18 units, the anti-knock property is improved, the olefin mass fraction decreases to below 30%, with a decrease of 16.78 percentage points, effectively reducing the oil pollution to the atmospheric environment; the coke yield increases by 3.73 percentage points; the conversion rate of feedstock has increased by 8.71 percentage points. This indicates that MIP-CGP technology has a good ability to reduce gasoline olefin content. While improving gasoline properties, it can significantly increase product yield, meeting the market demand for producing clean gasoline, reducing gasoline olefin content, increasing gasoline octane number, and increasing propylene yield.
