บทคัดย่อ

This research aimed to analyze the distillation of the ethanal distillation unit operation using the design of experiment (DOE) by a 2k full factorial method and engineering design principles with downscaled equipment to optimize production without altering structural parameters. The research result: firstly, residual plot analysis underscores the accuracy of data obtained through DOE, 2k full factorial experimental design, facilitating insightful result analysis applicable to the analysis and optimization of ethanol distillation production experiments. Secondly, at a significance level of α = 0.05, with an R-squared value of 99.90%. Optimized primary factors for target yield include a preheater temperature of 91 degrees Celsius, reboiler temperature of 95 degrees Celsius, cooling water flow rate of 200 liters per hour, and heating time of 19.4744 minutes. These operational conditions yield production exceeding 19.92 kilograms and facilitate an economical and efficient ethanol distillation process, promising significant cost savings. Manufacturers can use this study's findings and yield targets to identify optimal operating conditions.
