Vacuum System Failure Rejection

Another thing that I don't like while running a plant is having a down time. I hated it most when oil rejection occurs. Rejection will happen for various reasons. One of it which occasionally happen is the pressure vaccum drop. Oohh... when this happen, the oil Free fatty acid (FFA) content or oil colour will be out of spec. And this will force my plant operators to reject the oil to their respective crude oil tank. I'm still learning and exploring as well about the vacuum system in my plant. I need to maintain the dirty cooling tower pressure and temperature within the desired range. If the cooling water temperature slightly increase, it can affect the vacuum system and resulted in vacuum drop. It's ok if i know and can explain the why the down time or rejection happen. I hate it when i don't know the reason. It makes my life a little bit difficult explaining and answering all sorts of questions being bombarded at me just because i cannot meet the daily production target. Well, this makes me want to really make sure that all the processing parameters are within range and control. Need to prevent any plant breakdown and downtime from happening....
