Q
Material balance for a batch reactor
A
Rate of Accumulation = - Rate of Loss
2
Q
Rate of disappearance of a reactant
A
Rate of disappearance = (-rA)Vr
rA - reaction rate
Vr - reactor volume/volume of fluid in reactor
3
Q
Equation for calculating reaction rate
A
(-rA) =
moles of reactant reacting/
(unit volume)(time)
4
Q
What are the assumptions of a plug flow reactor?
When do they hold?
A
- At a given position, for any cross-section at right angles to the flow, there is no pressure, temperature, or composition change
- All fluid element have same residence time
- No diffusion from one fluid element to another
Hold when there is good radial mixing
