Heating and Cooling Systems of a Batch Reactor
The batch reactor is a generic term for a type of
vessel that is commonly used in the process industries. Its name is somewhat
misleading because vessels of this type are used for a wide range of process
operations including solids dissolution, product mixing, chemical reactions,
batch distillation, crystallisation, liquid/liquid extraction, and
polymerization. In some cases, they are not referred to as reactors, but rather
by a name that reflects the function they play (such as crystallizer, or
bioreactor).
Ablaze Glass Works is the leading Batch
reactor manufacturer in Vadodara.
A batch reactor is typically made up of a storage tank
with an agitator and an integrated heating/cooling system. The size of these
vessels can range from less than 1 litre to more than 15,000 litres. They are
commonly made of steel, stainless steel, glass-lined steel, glass, or an exotic
alloy. Liquids and solids are typically charged through connections in the
reactor's top cover. Vapors and gases can also escape through the top
connections. Typically, liquids are discharged from the bottom.
The batch reactor's benefits stem from its
adaptability. A single vessel can carry out a series of operations without
having to break containment. This is especially useful when working with toxic
or highly potent compounds.

Heating & Cooling System:
During the processing of products in batch reactors,
heat is usually liberated or absorbed. Heat is produced even when stored
liquids are stirred. Heat must be added or removed by a cooling jacket or
cooling pipe to keep the reactor contents at the desired temperature. Batch
reactors are heated and cooled using heating/cooling coils or external jackets.
To add or remove heat, heat transfer fluid flows through the jacket or coils.
External cooling jackets are generally preferred in
the chemical and pharmaceutical industries because they make the vessel easier
to clean. Three parameters define the performance of these jackets:
● Response time taken in
modifying the jacket temperature
● Ability to maintain the
uniformity of jacket temperature
● Ability to keep the jacket
temperature stable.
Ablaze Glass Works is a noted manufacturer and
supplier of Automated
batch reactors in Vadodara, Gujarat, India.
It could be argued that the heat transfer coefficient
is an important parameter as well. However, large batch reactors with external
cooling jackets have severe heat transfer constraints due to their design. Even
with ideal heat transfer conditions, it is difficult to achieve more than 100
watts/litre. Continuous reactors, on the other hand, can provide cooling
capacities in excess of 10,000 Watts/litre. There are better solutions than
batch reactors for processes with extremely high heat loads.
A quick temperature control response and uniform
jacket heating and cooling are especially important for crystallisation
processes or operations where the product or process is extremely temperature
sensitive. Batch reactor cooling jackets are classified into following types:
●
Single external jacket.
●
Half coil jacket.
●
Constant flux cooling jacket.
