Multivariate Statistical Analysis Finds Cause of Quench Oil High-Viscosity Issue Case StudyCHALLENGE Since mid-2017, the company had been dealing with a quench oil high-viscosity issue at the PreFac distillation column. SOLUTION An Aspen ProMV Desktop standard (continuous) model was developed, and the bad actors were identified. Within just a few weeks, Aspen ProMV TM revealed which variables were causing high quench oil viscosity. BENEFITS This application proved that Aspen ProMV can understand and resolve production problems faster to limit the losses. Aspen ProMV enabled the company to: • Highlight the top process variables highly correlated with viscosity issues • Guide process engineers to the real issue with missing details of LCO characteristic data • Look at how p
