Introduction to Oslo Crystallizer

The working principle is that the material flows turbulent at a certain flow rate through the heat exchange tubes of a tubular heat exchanger, driven by a circulating pump. During the flow process, it absorbs the heat released by the condensation of steam outside the tubes, and the temperature of the material increases without undergoing a phase change (vaporization) inside the heating tubes. The material enters the flash evaporation chamber for flash evaporation and cooling, releasing secondary steam, allowing the material to concentrate. As the material does not undergo phase change (vaporization) in the heat exchange tube, the concentration of the material in the tube does not change, and crystallization and scaling will not occur. Therefore, it can fully resist scaling and crystallization, and is suitable for the concentration of liquids that are prone to scaling and crystallization. Due to the full flow of materials inside the pipe, it is not easily blocked, making it particularly suitable for evaporation of suspended solids and high viscosity, high concentration fluids.

Typical examples of concentrated use

Corn syrup, alcohol waste liquid, lysine waste liquid, glutamic acid waste liquid, fermentation broth with bacterial cells, yeast waste liquid, penicillin waste liquid, and various types of chemical wastewater.

Typical crystal usage examples

Vc、 Citric acid, lysine, threonine and other amino acids, sodium chloride, ammonium chloride, ammonium sulfate, sodium sulfate, magnesium sulfate, sodium phosphate, sodium carbonate, ammonium carbonate, sodium nitrate, lithium hydroxide, lithium carbonate.

Product Features

Suitable for the concentration of liquids that are prone to scaling and crystallization; Not easily clogged, therefore it is particularly suitable for evaporation of suspended solids and high viscosity, high concentration fluids.

Application scope

The Oslo crystallizer is suitable for the crystallization of organic compounds such as citric acid and lysine, as well as the crystallization of inorganic salts such as NaCl, NaCrO7, NaHCO3, NaCO3 · 2H2O, (NH4) 2SO4, NH4NO3, etc.
