Evaporative Crystallizers
Buflovak designs and manufactures crystallizers of all basic types as the schematics shown here illustrate. Whether you need is for batch or continuous operation, or need to deliver small or large crystals, Buflovak will help develop an economical solution to your needs.

Forced Circulation Crystallizers
This approach to crystallization can be effective regardless of the solubility curve. However, many other factors, both economic and physical, must be considered in determining the ultimate choice. The submerged inlet vapor body offers the following advantages over the standard elbow inlet design.

  • Larger average crystal size
  • Narrows the crystal size distribution curve
  • Reduction in circulation pump horse power requirement


Vacuum or Surface Cooled Crystallizers
Generally, these types of crystallizers can be considered for materials having a solubility curve with a steep slope. The crystal size desired and the temperature level and nature of the solute will usually determine whether a vacuum- or surface-cooled unit is indicated.

Evaporation, Distillation & Separation
Evaporator is the descriptive name generally given to process equipment used to remove liquid by vaporization. The feed material may be a single liquid, liquid mixture, solutions or slurries, or any combination of these. Heat applied through some form or heat transfer surface is used to produce the vaporization. The concentrated product, as discharged, is still in fluid, pump-able form.

Distillation is the descriptive name generally given to process equipment used to separate a liquid mixture into separate components via vaporization and condensation. Buflovak designs systems using distillation in applications such as solvent recovery, product purification, solvent drying, VOC steam stripping, alcohol recovery, purification, and others. Our designs are determined through our years of engineering experience, process simulation and pilot testing.
