Plug flow reactor assumptions
WebIn the plug flow assumption, gradients of temperature and concentration are only considered in the axial direction, not the radial direction or the angular direction. Material balances for all the chemical substances involved along the length of the reactor (CO 2 , H 2 , CH 4 , and H 2 O) can be expressed as WebSep 12, 2016 · The ASP is formed by a plug-flow reactor (PFR) and a settler with recycling to the reactor. The biomass growth rate is described by a Monod function. ... key assumption is that the fluid is ...

WebTheory & Background Simplistic models of CSTR (continuous stirred tank reactor) and PFR (plug flow reactor) mixing behavior can be developed based on the assumption that ideal conditions exist. Even though this facilitates analysis, it is not always a very accurate representation of true reactor behavior.
