The Control Of A Fluid Catalytic Cracking Unit Complete Project Material (PDF/DOC)
The performance of the FCC units plays a major role on the overall economics of refinery plants. Any improvement in operation or control of FCC units will result in dramatic economic benefits. Fluid Catalytic Cracking (FCC) Units of Nigerian Refineries produced petroleum products at far below their installed capacities. This work is aimed at examining the control of a fluid catalytic cracking unit. The FCCU was designed to process 0.56bbl/hr of Escravos gas oil and fabrication of same was carried out. Equipment fabricated include Feed Surge Drum (Diameter 0.631m and Height 1.002m), Feed/LCO Heat Exchanger (Shell Diameter 0.260m, Tube Diameter 0.030m and Exchanger Length 1.000m), Feed/DCO Heat Exchanger(Shell Diameter 0.275m, Tube Diameter 0.0245m and Exchanger Length 1.000m), Feed/Slurry Heat Exchanger(Shell Diameter 0.260m, Tube Diameter 0.024m and Exchanger Length 1.000m), Feed Fired Heater (Base Diameter 0.872m, Height 1.745m and Tube Diameter 0.024m), Riser Reactor (Diameter 0.545m and Height 1.817m), Main Fractionator (Column Diameter 0.520m and Column Height 2.925m) and Overhead Condenser (Shell Diameter 0.310m, Tube Diameter 0.0245m and Condenser Length 1.000m). Both manual and Hysys simulation software were used to carry out the design and the results obtained were compared to ascertain most acceptable technique for the design of FCCU. While Hysys simulation gave more detailed and effective results, the manual design technique shows little discrepancy to Hysys simulation result. Therefore, the manual design technique is also valid and can also serve in the absence of the software for FCCU design.
