Unformatted text preview: This is a simulation for a 3-Effect Backward Feed Evaporat or Syste 1. Flow Diagram of the 3-Effect Backward Feed Evaporat or Syst 2. Flow Diagram of the 3-Effect Backward Feed Evaporat or Syst 3. Summar y of Data from the Base System 4. Summar y of Data from the Case Study System These f low diagrams can be altered where highlight ed green and ot content on the Case Study will result in changes in the liquor f low w for the Base Syst em and one for the Case Study Syst em, with calcul For mat-->Sheet-->Unhide. Following the summar ies, five cases from the Case Study System ar Backward Feed Evaporat or Syst em with a Flash Syst em to changes not change accordingly if edit ed and therefore, if fur ther cases are r em. There are four worksheets that make up this simulation that follow this w tem (Base Syst em) tem with a Flash System (Case Study Syst em) ther values on the diagram will change to ref lect the alt erations. Changes in with the pur pose being to keep the solid f lowrate constant. There are two sh lations of steam table values on them. These can be accessed by unhiding th re included for ease of compar ison for a sensitivity analysis. Sensitivity of th s in input liquor t emperature and solids content was investigated.
