OSLO Crystallizer

An OSLO Crystallizer, also known as a classified-suspension crystallizer, is a crystallization system designed to produce large, coarse crystals with a narrow size distribution. It uses a controlled fluidized bed to promote uniform crystal growth while minimizing crystal breakage.

The OSLO Crystallizer operates through two main sections: a classifying crystallization chamber and a liquor-vapor separation zone. The fluidized bed progressively removes supersaturation from the incoming liquor, promoting crystal growth. Solvent removal in the separation zone develops supersaturation, after which the liquor is cooled and recycled through a heat exchanger.

The controlled fluidized-bed environment promotes steady crystal growth with reduced crystal breakage. Unlike crystallizers that rely on mechanical agitation, the OSLO design minimizes attrition, helping produce larger crystals with a more uniform size distribution.

A classified-suspension design allows crystals to be classified according to their growth and size within the crystallization chamber. This supports controlled crystal growth and helps achieve a narrow crystal size range while reducing unwanted crystal attrition.

No. The OSLO Crystallizer operates without mechanical agitation, which reduces energy requirements and minimizes the mechanical breakage of growing crystals. This makes the system suitable for processes where crystal size and quality are important.

An OSLO Crystallizer can be used for both reaction crystallization and separation crystallization processes. The appropriate configuration depends on the characteristics of the process and the desired crystal properties.

Key advantages include large and coarse crystal production, narrow crystal size distribution, reduced crystal attrition, lower energy requirements, lower operating costs, long continuous production cycles, and controlled crystal growth.

The system avoids mechanical agitation and uses a fluidized bed for controlled crystal growth. This reduces mechanical interaction and breakage of growing crystals, helping maintain crystal size and quality during extended operation.

Yes. The OSLO Crystallizer is designed to support long continuous production cycles, with controlled crystal growth and reduced attrition. This can help reduce interruptions and operating costs associated with frequent washing or maintenance.
