Abstract: The location of temperative-sensitive plates in the turpentine dual-tower continuous distillation system under both static and dynamic conditions was determined using Peng Rob method. The result shows that the location of sensitive plates of low-boiling-point column varies within three plates, while the No.16th plate is the sensitive one in high-boiling-point column. Based on this study, the parameters can be promptly adjusted to keep the stable temperature of the sensitive plates, so as to ensure the distillation efficiency and product quality.
