| Abstract: | As the feedstock in the 28 000 b/d two-stage residue fluid catalytic cracking(TSRFCC) unit in PetroChina Changqing Petrochemical Company was high in density and carbon residue,the settler and main fractionator suffered from serious coking which affected the normal operation of the unit.After the construction of an 15 100 b/d solvent deasphalting unit to remove the resin gums and asphaltene from the vacuum residue,the quality of FCCU feedstock was greatly improved.The addition of spent catalyst circulation l... |
