On a second page (which you may find convenient to generate with a spreadsheet program), prepare a table to accompany the flowchart. The column headings should be the stream identifiers from the flowchart (S₁, S₂, S₃, or whatever system you used). The row labels should be as follows: T(°C), P(atm), PVC(kg/h), CPVC(kg/h), H₂O(kg/h), Cl₂(kg/h), HClkg/h), NaOH(kg/h), NaHCO₃ (kg/h), NaCl(kg/h), Na₂CO₃(kg/h), CH₄(kg/h), C₂H₆(kg/h), C₃H₈(kg/h), 02(kg/h), N₂(kg/h), CO₂(kg/h), TOTAL(kg/h).

Begin by filling in all known quantities in the appropriate location in the table, and put dashes (—) in every cell of a stream column corresponding to species not present in that stream. There after, whenever you determine the temperature, pressure, flow rate, and/or composition of a process stream, calculate and enter the corresponding values in the table. When you have worked through the entire case study, every cell should contain either a dash or a number. When doing mass/mole conversions, use 35.45 as the atomic weight of chlorine.
