WebOct 9, 2024 · A single CSTR suffers from relatively slow heat and mass transfer. Also, residence time control is poor. Each molecule does not necessarily flow through the reactor at the same rate. A series of CSTRs can be connected for better control over residence time. Agitation is a really important part of the CSTR. WebMass transfer coefficients are often, although not routinely, measured by photobioreactor developers [3,4,5,6,7,8,9]. Knowing mass transfer capabilities is essential information for judging the potential of a photobioreactor’s geometry to scale its performance when other bottlenecks are removed.
