Sianzation… Can you feel it? It’s hard to get back on track with lectures and study of Chemical Engineering. Lucky this time is 3.1 with training @ CPTC, SIP and MP. Imagine it’s going to be books and projects again! I think I will just die… Recently too, my life became so happening! I do not wish to talk about it as this entry of mine isn’t for that. Read R’s blog will do.

Anyway, I need to blog to keep track my reflection “What I’ve learnt this week for Practicals only”.

Monday, my groups had climbed C-100 and C-101. C-100 is estimated to be about 10 storey (35m) high. It was anxiety and excitement experienced. Luckily enough, my ankle was sort of not so pain, I’ve been anticipating about climbing the tower since the first day we had practical. This activity was like a treasure hunt where we have to hunt for and identify the tags on the temperature and pressure gauges, sampling point and etc.

Through this activity, it has allowed me to have a clearer view of the distillation column and its operations. Thereafter, it was easy for me to draw my PFD diagram too. Though for the past 1 week, we had been doing line tracing in different part of the plant, I feel that it was essential for us to know the operations better.

Tuesday, it was Cooling Water system, Deluge Valve and N2 system. Through the practical, my trainer has taught us to change Float system to Bubbler System and vice versa. It was complicated again. There were many valves and different parts we’ve to monitor and turn. Hence, when debriefing was done, I could have a clearer picture of each procedure and it purposes.

Example, we have to ensure that the Cooling Water System is on before the start up of plant, follow by instrument Air. The purpose of having a float and bubbler system is simple. Basically, float system is always use in CPTC for power saving as it does not activate and make use of the compressor. However, the disadvantage is that it needs frequent patrolling so as to ensure that there is no overflow in the basin. Where else, bubbler system needs the activation of the compressor and hence, a swing by-pass is needed for instrument air to activate the compressor and the bubbler level transmitter to be send to controller. This process of system change would almost be completed by changing 10-PCV-502 to automation and later throttled the side valve to 3.04barg to meet set-point controlled in the DCS unit.

For deluged system, there are 3 ways to activate it. Basically, burn it, activate the emergency button located in the plant and activating it from the DCS. For N2 system, I’ve also learn the operations.

Alright. Enough. To be continue… just don’t wish to forget some facts learnt…
