A mass balance can also be taken differentially. The concept is the same as for a large mass balance, but it is performed in the context of a limiting system (for example, one can consider the limiting case in time or, more commonly, volume). A differential mass balance is used to generate differential equations that can provide an effective tool for modelling and understanding the target system. WebWe use the Peng–Robinson equation of state and the reaction-coordinate method to compute the extent of reaction, in moles of per unit time (e.g., hours), for user-set values of the reactor temperature in degrees Kelvin and pressure in bars. This Demonstration carries out the mass balance around the reactor and splitter in order to compute the ...
