Modeling and Simulation of Reaction and Fractionation Systems for the Industrial Residue Hydrotreating Process

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
