Cstr pfr in series
WebTwo or three CSTRs in series or a CSTR-PFR array can be used in mass processes. In the most common two CSTR or CSTR/PFR arrays, the PB solution is added to the first CSTR that operates between 20% and 40% solids at steady state. The second CSTR operates at solid contents between 50% and 80% depending on reactor volume and design. WebThe short PFR (8.9m) was used with a flow rate of 600mL/min. In the CSTR, a mixing speed of 240 rpm with the large impeller was used. The results are shown in Figures 1-5. Figure 1: Conductivity of CSTR outlet (uS/cm) as a function of time (s). Figure 3: Cumulative distribution, or F (t) function. Figure 2: Residence time distribution, or E (t ...
