CHEM designs and manufactures diverse types of
Crystallizers, which includes the Adiabetic Vacuum
Type, Evaporative Forced Type, Draft Tube Baffle Type,
Spray Evaporators Type, Oslo Type, etc.
The
other type of Crystallizer designed and manufactured
by Chem is the Batch Vacuum Crystallizer which
is appropriate
where the operating temperatures are very low and
achievable only by exceptionally high vacuum. The
Batch Crystallizer is preferred as it costs less
to operate than a Continuous Vacuum Crystallizer.
Chem also designs the Surface Cooled Crystallizer using a Shell And
Tube Exchanger, and is applied for operations at
temperatures below which it is not economically viable
to use vacuum equipment, or with solutions having very
high boiling point elevations.
For applications where
refrigerants are used to achieve operating
temperatures, Chem designs and applies the Direct Contact Type Refrigeration
Crystallizer on the principles of forced
circulation or draft tube baffle is used,
where the refrigerant is mixed with the slurry.
