Naming rules for heat exchangers and air coolers in the flow diagram
Thread Content
Dear everyone: In the flow diagram of the catalytic cracking unit, the slurry flow path is as follows: Slurry pump P208ABC —— E201AB —— P209AB —— E203AB —— E209AB. The overhead gas flow path is: E202A~J —— A201A~X —— E215A~J —— D201. I would like to ask everyone what the naming rules are for the heat exchangers and air coolers in the flow diagram? Why does it feel completely rule-less? Do anyone else share this feeling?
It’s impossible. Take a closer look, for example at the distillation unit: whether going from bottom to top or from top to bottom, the pumps are definitely numbered in sequence. Also, cold exchange equipment will definitely work smoothly.
They are generally numbered according to the processes and procedures, in a systematic manner
