Performing Mass Balances Using Spreadsheets Spreadsheets are a handy tool for performing mass balances. The main advantage is that once you have the problem solved, you can easily analyze any set of conditions. For example, if you were given the information that the fresh feed entering your process would contain 25 mol% benzene, 25 mol% xylene, and 50% toluene at a rate of 100 mol/h, and then your boss told you that process conditions have changed upstream such that the new composition is 10 mol %, 20 mol%, and 70 mol%, respectively, all you would need to do is plug the new values into your spreadsheet and you would instantly know all the adjusted values for the remaining streams in your process. That sure beats having to do the calculations again by hand! Here are a few tips to keep in mind when solving mass balances in Excel: 1) As a rule-of-thumb, always try to keep the process flowing from left to right. Sometimes, streams enter and exit from the top and bottom of units as well. 2) Detailed process icons are not necessary. Draw your process units as boxes. 3) Keep your process spread out on the sheet so you have plenty of room to label your streams
