Process flow diagrams (flow sheets)
Show the sequence of equipment and unit operations inthe overall process. The equipment and the unitoperations are connected with process streams, lineswhich represent the movement of material to/fromprocess units. Typically these streams are labeled with
information regarding the amounts, compositions,temperatures, pressures, etc. of the components. Simplify visualization of the manufacturing procedures Indicate the quantities of materials and energy
