Abstract
Although distillation has been extensively studied and resulted in various types of modern distills. But up to now pot still is still considered as the best type of batch still used in spirits distillation industry. Goose neck (Alembic) on top of the pot is the enrich section in the still, natural cooling privies reflux that is crucial to quality of spirits. It is very different to other industrial distiller that usually with an adiabatic enrich section. In our laboratory a packed bed distiller was design and constructed to be the improvement for pot still. The packed bed distiller provided great amount of contact area for better mass transfer effects, and controllable temperature field to be similar to pot still operating conditions. In this thesis the temperature control system for the distiller was design and studied. The enrich section of the distiller was divided into four stages; each stage was surrounded with water jack to control the operation temperature to the setting values. The operating temperature in each section was measured with a PT100 thermal couple, and the temperature was controlled by a virtual controller programmed with LABView. The control system could maintain the temperature in each section to the set goal within the error of 1.5℃. A mathematical model based on heat and mass transfers in distiller was developed and implemented with Simulink program. The numerical simulations gave consistent results to experiment data. Based on this primary study to use the mathematical model to design a better control schema for the system to minimize the control error was suggested.
