Batch Reactors

 

 

Type of Reactor

 

Characteristics

Simple Batch

 

Reactor is charged via two holes in the top of the tank; while reaction is carried out, nothing else is put in or taken out until the reaction is done; tank easily heated or cooled by jacket


General Mole Balance Equation

 

Assumptions

1) No inflow or out flow FA0 = FA = 0

2) Well mixed

Constant volume V = V0 (e.g. Liquid Phase or Gas Phase in a steel container)

In terms of conversion

The reaction time necessary to reach a conversions X in a batch reactor is

. The following table gives reaction times for first (rA = kCA) and second (rA = k) in a batch reactor

The following table gives the various times necessary to process one complete batch.
