Operating large reactors in industry can be expensive, so a common trick used to reduced costs is to operate multiple CSTRs in series, in which the … Webb11 juni 2024 · With only three CSTRs-in-series, the RTD starts looking more like an F-curve. With 130 CSTRs-in-series, RTD is about the same as PFDR with axial dispersion number 0.004, as described above. A perfect plug flow reactor (D/uL = 0) corresponds to an infinite number of CSTRs-in-series of infinitesimally small volume.

WebbCSTRs operated in series approach plug flow and therefore give much higher levels of throughput for the same conversion. When we have two reactors of unequal size in series, highest conversion is achieved by keeping the intermediate concentration as high as possible. This implies putting the small CSTR before the large CSTR. http://quasareg.com/farm-digesters-energy-manure/
