Selecting the Right Temperature | FSC 432: Petroleum Refining

Selecting the right temperature in the vacuum distillation column is critical to control the risk of coking in the column. The Watson Characterization Factor (Kw) may be used to estimate the upper temperature limit for vacuum distillation to avoid coking. Figure 4.6 shows an empirical correlation between Kw and the temperatures above which .
