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.
