Distillation Column
In the the Chemical Enginneering Lab at CSULB there is a total reflux eight-stage glass binary distillation column at atmospheric pressure. The components that need to be separated are 1-propanol and 2-propanol. These two compounds are isomers with fairly close boiling points. They are separated based on their physical propertis. With the battch distillation might be almost impossible to do the sepapration. Capacity of the reboiler is 20 L. The Supply of pressure and steam is regulated by a newly-established controll system consisting of a steam pressure sensor, a Fieldpoint data communication and aquisition module from National Instrument, an electromagnetic control valve, and a LabView control algorithm designed by dr. Jang. The data was taken frm one of the six computers near the column which had the control algorithm. The Fieldpoint module needed to be connected with the column via Internet. In this column at different stages there are 10 thermocouples (K type) inserted in each tray. Trays used in the labs distilation colum have buble trays. These distilation are frequently used in the petroleum refining, in natural gas processing and in petrochemical production. 1propanol
