Term

Definition
A plug flow reactor is a continuous reactor in which a 'plug' of fluid moves along a pipe with no axial mixing and perfect radial mixing 


Term
Define: Continuously Stirred Tank Reactor 

Definition
A CSTR is a batch type reactor in which all contents of the reactor are assumed to be evenly mixed 


Term

Definition
An equation or set of equations used to describe the rate at which a reaction occurs 


Term

Definition
an equation or set of equations used to describe the ideal reaction conditions including space time, volume, flow rate, conversion, etc. 


Term

Definition
The amount of nrg, in the form of heat, that must be added or removed during a chemical reaction to all the reactions to proceed 


Term
Overall heat transfer coefficent, U 

Definition
Ratio of the flux of heat transfer to the driving force behind the transfer (ie the temp difference) 


Term

Definition
the max temp acheivable in an adiabatic system 


Term

Definition
Fractional volume change δA=(V_{X}_{A=1}V_{XA=0})/V_{XA=0} 


Term

Definition
reactor that recycles a protion of the effluent obtained at the outlet of the reactor back to the inlet 


Term

Definition
Amount of product obtained relatice to the initial amount of reactant
Yield=((1/V_{P})N_{pf})/((1/V_{r})N_{ri}
Where N_{pf} is the final moles of product and N_{ri} is the initial moles of reactant and Vp and Vr are the stoichiometric coefficients 


Term

Definition
Amount of product obtained relative to how much was reacted
((1/V_{P})N_{pf}))/((1/V_{r})(N_{ri}N_{rf})) 


Term

Definition
The proportion of material that that react
XA = 1CA/CAO



Term
What assumptions can you make about a CSTR reactor model? 

Definition
You can assume that a CSTR is
run at steady state with continuous flow of reactants and products; the feed assumes a uniform
composition throughout the reactor, exit stream has the same composition as in the tank 


Term
What assumptions can you make about a PFR reactor model? 

Definition
? You can assume steady state,
constant density, constant tube diameter, a single reaction is occurring.
