You need to submit the graphs you used and how you solved on the graph to get the value. The graph should clearly show what are the lines you drew. The gas oil obtained from the atmospheric distillation of a refinery in the USA is combined with the coker gas oil and fed to an FCC unit. The feed mean average boiling point is 576C and has density of 960kg/m3. a) Use the charts of Chapter 6 available in your formula sheer to find the yields of the following FCC products: coke, fuel gas, LPG and gasoline. Specify whether this is wt % or vol % ( 43 marks) FCC yield calculation Charts (Figures 6.17 to 6.23 ): FIGURE 6.17 Effect of feed composition on conversion at constant operating conditions.
