Scraped Surface Heat Exchangers

There are many benefits to using continuous cooling crystallization. Below, we highlight some of these:

  1. Low-temperature operation – low corrosion rates, less product degradation, no tar formation
  2. Enclosed systems with little or no leakage
  3. Favorable equilibrium – wide spread of organic chemical freezing points
  4. High purity – crystals formed usually are 100% pure
  5. Continuous process using Armstrong/Chemtec equipment
