The document discusses types of chemical reactors used in engineering, specifically defining a chemical reactor as equipment for facilitating chemical reactions to produce desired products. It outlines three main types: batch reactors, which operate in a closed vessel with reactants added all at once; continuous stirred tank reactors (C.S.T.R), which mix reactants continuously in a closed tank; and plug flow reactors (P.F.R), characterized by a flow of reactants in plugs with uniform concentration. Each reactor type has distinct operational methodologies and designs aimed at optimizing chemical reactions.

2. WHAT IS REACTOR?
 A chemical reactor is a process equipment where in
chemicals are fed in order to make them chemically
react with each other for the purpose of making a
desired product.

3. TYPES OF REACTOR
 Batch Reactor
 Continuous Stirred Tank Reactor (C.S.T.R)
 Plug Flow Reactor (P.F.R)

4. BATCH REACTOR
 A batch reactor is a closed vessel in which
reactions happen and it is a non-continuous
type of reactor. The reactants are fed in to the
reactor all at once initially. The vessel contains
an agitator. The purpose of the agitator is to
mix the reactants thoroughly so that the
contact makes them react together efficiently
and produce products.

5. CONTINUOUS STIRRED TANK REACTOR
 A continuous stirred tank reactor (C.S.T.R) is
also often called a mixed flow reactor (M.F.R). In
this reactor also the reaction occurs in a closed
tank. The tank also has agitator in order to mix
the reactants thoroughly. It is different from
batch reactor in the sense that the name itself
indicates it is continuous type of equipment.

6. PLUG FLOW REACTOR (P.F.R)
 A plug flow reactor (P.F.R) is also sometime
called a continuous tubular reactor (C.T.R). In an
idealized model, the profile of the reaction
mixture can be considered to be made up of a
number of plugs and each plug having a uniform
concentration.
