.24 inch diameter by 0.24 inch length protruded Pro-Pak packing. This packing has a stainless steel material of construction with a surface area of 372 square feet per cubic-feet. The material of construction of the entire body of the column is vacuum-jacketed 3" X 60" glass. There are internal liquid distributors at the halfway point and at the top of the column. There is also a packing support screen on the bottom of this section.The reboiler has a round still pot character constructed of glass. The reboiler is surrounded by an electric-heating mantle, which contains four sections. Three of the four heaters were active during our experimentation. Each heater is rated at 1000 Watts. The voltage supply is at 120 volts. During our design of experiments, our team controlled the percentage of the voltage that was allowed to flow through the system. The reboiler also contains a bottom sample port. This piece of equipment consists of a glass tube that extends from the center of the reboiler up through the top surface of the reboiler and connects with a two-way glass valve. This valve allows either a nitrogen purge to be placed on the reboiler or bottom material to be siphoned out. During normal operation, the valve is positioned to allow the nitrogen to blanket the reboiler in order to maintain steady boiling. Only during sampling is the valve position changed to that a sample may be siphoned out.The control system consists of fiver thermocouples, four heaters, a rotameter, and a magnetic actuator. A thermocouple is located at both the cooling water inlet and outlet. Also, thermocouples are located at the column reflux, reboiler, and center of the column. The temperature reading is transmitted to a digital monitor for display at the base of the column. The heaters are controlled by a dial setting on the control panel, which ranges from 10% to 100% of the voltage supply. The water flow rate can also be controlled from this...
