Taguchi’s Parametric Design Approach for Determining the Significant Decision Variables in a Crude Distillation Unit (CDU)

The purpose of this study is to conduct a research on the implementation of Taguchi’s parametric design approach in selecting the appropriate variable for optimization for crude distillation unit (CDU). The main aspect that that will focusing in this study is on the maximizing the profit based on different case studies. A dynamic CDU model is developed using HYSYS environment in order to test the case study. 13 variable and 3 level is chosen to be used in this project. This variable is selected due to their function as manipulated variable in controlling the process. Each sequence of variable is tested simultaneously in HYSYS. The validation process on result is done by comparing the optimum value through a experiment in HYSYS. On the other hand, the analysis of mean and variance, ANOM and ANOVA is conducted to find the most valuable and profitable sequence of variable. The result obtain is in term of profit which is the highest profit is 1.7 million RM/day with the optimum configuration is A1B3C1D3E3F1G1H1I1J1K3L1M1N3O1.
