Abstract. Hydrocyclones are simple and robust separation devices with no moving parts. In the past few years, their use in animal cell separation has been proposed. In this work, the use of different hydrocyclone configurations for Chinese hamster ovary (CHO) cell separation was investigated following an experimental design.

The clear depth of the working of the hydrocyclone is different from others in the literature. 2. Design of the cyclone separator. The hydrocyclones are the most robust dust separators. In a traditional hydrocyclone, the contaminated water enters tangentially and forces the flow in a spiral motion along the walls of the structure.

A hydrocyclone with a volume of 2.56 cm 3 was studied as a potential cell retention device for mammalian cell cultures (6 L volume). For the feasible operation range (0.9 to 1.6 L/min flow corresponding to pressure drops of 0.4 to 1.3 bar) the hydrocyclone was characterized with regard to flow split (underflow-to-overflow ratio) and flow ratio (underflow to supply).

hydrocyclone based liquid-liquid separation processes have only been accepted within the last 10 years. There has been a growing awareness within the oil and gas industry of the importance of effective fluids handling, and in particular the preservation of droplet size, by minimizing shearing forces within the process flow.

hydrocyclone technology has been shown to provide extremely high throughput operation using an entirely passive design without the need for precise control over inlet flow rates to maintain high separation efficiency. For example, a commercial hydrocyclone with 125 mm chamber diameter operating at inlet pressures up to 124 kPa, corresponding to ...

Hydrophilic par­ ticles are thrown to the porous cylinder wall and are discharged as tailings in the underflow. Hydro­ phobic particles encounter air bubbles, which are sparged radially through the porous wall. The high shear force at the wall generates small air bubbles and provides for intense interaction between par­ ticles and bubbles.

The gas moves toward the center of the hydrocyclone with the oil and exits the unit through the reject port. A small amount of gas can improve performance, but too much gas disrupts the smooth flow of the oil core and bottlenecks the flow of oil out of the reject, Walsh said. Important trade-offs must be considered when designing a …
