The first problem is that the lumped compositions whose normal boiling point is lower the real 

IBP value should be removed. Therefore, their proportion should be set to zero, which is based on 

the separation efficiency factor proposed by García et al. [29]. In this way, the proportions of 

remaining lumps inevitably increase. To handle this problem, it is necessary to adjust the proportions, 

which has been presented in the previous work [30]. Figure 6b and Table 1 show the results of the 

experimental value, simulated value with basic and improved library of the residue feed. Since the
