First Day Reflection (26 May, Tuesday)
Today we went to NTU's lab to view the Distillation system. We listened to the teacher adviser's talk about the system and its parts, then we had to operate the system by ourselves. Step one was to prepare the mixtures but the mixtures were already prepared for us. Then, we had to pump up 8 litres of the mixture into the reboiler which will heat up the mixture. After that, 4 litres of mixture has to be pumped up into the feed tank. We had to make sure that all the valves were closed except for one valve 10. Then we turn on the power to the control panel. We had to set the feed pump controller to 2.5 units, then off the power. Then, we open valve 5 for the cooling water to the condenser; set its flow rate to three litre per minute, then on the reboiler heater. Then we had to wait for the droplet to drop into the decanter.
