Identity number:D00042
DCC:FB
Status level:Standard
Name:Process flow diagram
Content of information:Description:
The process flow diagram depicts a process or a process plant by means of graphical symbols, interconnected by flow lines. The graphical symbols represent equipment and the lines represent flows of mass and energy or energy carriers.
Mandatory content of information:
– Kind of equipment necessary for the process, except drives;
– Reference designations for equipment, except drives;
– Route and direction of ingoing and outgoing material and energy flows;
– Denomination and flow rates of ingoing and outgoing materials;
– Designation of energy flows or flows of energy carriers;
– Characteristic operating conditions.
Optional content of information:
– Denomination of flows and flow rates of process fluids between the process steps;
– Flow rates or amounts of energy or energy carriers;
– Essential valves in the logical process position with respect to their function;
– Functional demands for process measurement and control at essential points;
– Supplementary operating conditions;
– Denomination of equipment and characteristic data of equipment;
– Denomination of drives and characteristic data of drives;
– Elevation of platforms and approximate relative vertical position of equipment.
