  2. Column Hydraulics • Radfrac block • Report •  include hydraulic parameters • Run simulation • Results • Radfrac Block • Profiles • Hydraulics tab • ASPENPLUS: 

  3. In-Class Exercise P = 2 bar sat’d liq 20 stages Feed = above stage 10 D = 11.8 kmol/hr RR = 1.5 Benzene 11.8 kmol/hr Toluene 11.8 kmol/hr

  4. In-Class Exercise

  5. In-Class Exercise AspenPlus Tray sizing

  6. Controller Type Kc (gain) I (reset time) F (filter) Flow 0.5 0.3 min 0.1 min Level (surge) 2 (reactor) 10 (others) See text Pressure 2 10 Chapter 3: Controller Tuning

  7. Chapter 3: Controller Tuning • F, P, L - are simple controllers • Temperature & Composition • More difficult • Why ? • A: lags or deadtime • Simulators respond instantaneously • To make more realistic • Add lag time in control loop • Table 3.1 Typical values Rest of Chapter 3: Tuning techniques
