Conversion and reactor sizing
CSTR - to determine volume necessary to achieve conversion X. The design equation for CSTR is: 
Batch reactor - to determine time necessary to achieve conversion X
PFR- To determine Volume necessary to achieve conversion X
Link Title
PBR-To determine catalyst weight necessary to achieve conversion X
Area under the curve of Levespiel Plot( FA0/-rA vs X) = PFR volume !

4 numerical methods to evaluate integral: (1) Trapezoidal method (2) SImpson's One third rule (3) Simpson's three Eight's rule (4)Five Points Quadrature Formula (MOST ACCURATE)

Reactor in Series (*Only valid if there are no side streams)
We want to minimize the volume required to reduce cost during design
The Volume in CSTR can be estimated from the graph
Steady state
Small scale operation
testing new processes
manufacturing expensive products
Slow reaction, need long hours to complete
Normally used for liquid and gas phase reaction
