Figure 10. Sensitivity results of the side draw rate and ASTM D86 curve change of different products 

and methods: (a) naphtha with the HCRSRK method; (b) naphtha with the data-based delumping 

method; (c) diesel with the HCRSRK method; (d) diesel with the data-based delumping method. 

 

Figure 11. Sensitivity results of the side draw rate and temperature change of different products and 

methods: (a) naphtha with the HCRSRK method; (b) naphtha with the data-based delumping method; 

(c) diesel with the HCRSRK method; (d) diesel with the data-based delumping method. 

The experiments of Figure 12 are performed with the feed of fractionator from a HCR since the 

added ashphaltene lump is out of the range of the HCRSRK. Figure 12 shows the simulation accuracy
