Completely stirred tank reactor

The continuous stirred-tank reactor (CSTR), also known as vat- or backmix reactor, mixed flow reactor (MFR), or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering and environmental engineering. A CSTR often refers to a model used to estimate the … See more Modeling A continuous fluid flow containing non-conservative chemical reactant A enters an ideal CSTR of volume V. Assumptions: • perfect … See more CSTRs facilitate rapid dilution of reagents through mixing. Therefore, for non-zero-order reactions, the low concentration of reagent in the reactor means a CSTR will be less efficient at removing the reagent compared to a PFR with the same residence time. … See more While the ideal CSTR model is useful for predicting the fate of constituents during a chemical or biological process, CSTRs rarely exhibit ideal … See more Cascades of CSTRs, also known as a series of CSTRs, are used to decrease the volume of a system. Minimizing Volume As seen in the graph with one CSTR, where the inverse rate is plotted as a function of See more • Laminar flow reactor • Microreactor • Oscillatory baffled reactor See more WebApr 6, 2024 · This study evaluated different strategies to increase gas–liquid mass transfer in a randomly packed gas stirred tank reactor (GSTR) continuously fed with second cheese whey (SCW), at thermophilic condition (55 °C), for the purpose of carrying out in situ biogas upgrading.
