摘要:
In September 1999, Kyokuto Petroleum Industries (KPI) commissioned a MagnaCat catalyst separation unit in its residual fluid catalytic cracker (RFCC) at its Chiba refinery in Japan. The operating benefits included yield improvements at a constant catalyst-makeup rate, higher feed vacuum residues content due to improved coke selectivity, and reduced catalyst makeup rate at constant equilibrium activity. The MagnaCat process and KPI facility are described. The performance of the magnetic separator and benefits to the RFCC are outlined.
