Industry Practice of MGD Technique in the Catalytic Cracking Plant

The catalytic cracking plant in a chemical industry company uses long residua of DaQing as feedstock to produce rich propylene and high octane number gasoline.For raising propylene yield and decreasing olefin in gaso-linet,he MGD technique developed Beijing Research Institute of Petrochemical technology was used.After indus-try runningt,he result showed that propylene yield raises nearly by 1.7%,LPG and Diesel oil and Gasoline yield amounts to 85.12%,olefin in gasoline decreases by 10% and octane number gets a little progress.
