Tubular reactor or plug flow reactor - BioMineWiki

Tubular reactors resemble batch reactors in providing initially high driving forces, which diminish as the reactions progress down the tubes. Flow in tubular reactors can be laminar, as with viscous fluids in small-diameter tubes, and greatly deviate from ideal plug-flow behavior, or turbulent, as with gases. . Cell recycling is, however, an .

Summary Report Sequencing Batch Reactors

----- 2,0 2.1 A treatment plant utilizing the SBR concept has only one type of process unit, the batch reactor tank. It is possible, even preferable in many cases, to link several identical reactor vessels in a multiple tank config- uration, to limit the size of in- dividual units and increase flex- ibility.

Variable-volume operation of a stirred tank reactor

mixed reactor has the same concentration and temperature as the reactor contents. At the other extreme, the reactor is not stirred and there exists a zero level of mixing. This means that there is no mixing of re-actants of different levels of concentrations in the reactor. The batch reactor is a tank reactor that has a zero level of mixing.
