Dear all expert
I am junior engineer. My work is about process design.
When I study the process engineering design gudeline. It is identify only criteria or guideline that we need use it for design or calculation. But it is not tell us the reason why we need use that criteria, what is theory or concept to support that criteria. Such as why criteria of shell and tube heat exchanger temp approach = 10 C, Air cool 15 C, Pressure drop of inlet line PSV < 3% of set P, Flow and pressure control valve's %EQ charateristic use %EQ and etc.
If anyone have document that both process eng. design guideline and theory/concept to support that guideline.
Could you please share to us.
Your help is my appreciate.
Best regard,
Sapao
