Chemical Processing

Centrisys have been used in the chemical industry where applications can be very diverse including the following types of physical separations:

Degritting – the removal of a small fraction of insoluble material above a certain particle size while retaining the remainder of the slurry with the liquid discharge.
Classifying – splitting the particle size distribution of a feed slurry into a more course and more fine fraction. Often the centrifuge acts to de-agglomerate particles when the finer cut particle is the goal.
Thickening – removing a small portion of the liquid in the feed slurry to conform to a product spec while retaining the fluid consistency of the liquid (as an alternative/supplement to spray drying).
Dewatering – removing a large portion of the liquid to generate cake product with a solids consistency.
Purification – removing solids from a liquid product.
Re-pulp/dewatering – for slurries which filters poorly, cake product can be washed using co-current or counter current stages of centrifuge dewatering in series.
3 Phase separation – for separating 2 liquids independently of a solids phase.

Centrifuges are custom designed based on Material of Construction constraints imposed by design and operating conditions (typically pressure and temperature) of the process. Further, such equipment is customized to conform to the area classification of the process environment.
