WebIn case of problems, reaction runaway may appear due to loss of cooling water in the reactor, over- or miss-charged reactant, external fire, and loss of agitation or wrong reaction temperature in reactor. Such cases are difficult to predict, almost not possible to control, and can lead to explosion. WebRunaway Reactions in Plug Flow Reactors* Phase Plane Plots We transform the above temperature and concentration profiles into a phase plane in the following manner. (1) (2) First, we obtain the temperature and concentration profiles and then use these to obtain the phase plane plot of CAvs. T.
