In crystallization processes, the most commonly used types of crystallizers are DTB, Forced Circulation, and Oslo Type crystallizers.

 Designing a known crystallizer with a suitable production rate for the process involves primarily determining the active volume (residence time) and, along with it, the internal design, dimensions, and auxiliary components.

 ASOS specializes in identifying the most suitable technologies for the process needs of Crystallization Facilities.

The factors considered in determining the type of crystallizer include product characteristics and factors that enable economic production, as listed below:

  • Product size
  • Product quality (purity and other important physical properties)
  • Process energy efficiency
  • Establishing mass and heat balances
  • Determining the residence time that ensures product properties
  • Determining crystallizer dimensions according to design criteria
  • Calculating heat transfer surface area and circulation rate

ASOS offers the following Crystallization Technologies to industries according to their needs:

  • Forced Circulation (MSMPR) Crystallizers.
  • Draft Tube Baffle (DTB) Crystallizers.
  • Oslo Type Continuous Vacuum Crystallizers.

 

 

DTB Crystallizer

Draft Tube Baffle Type (DTB) Crystallizers are suitable for vacuum cooling and processes with moderate evaporation rate. Due to the small amount of additional heat required in the process phase, it has a positive ef...
