Spherical cyclones are a type of cyclone separator that are commonly used in various industries for gas-solid or liquid-solid separation. Cyclone separators are devices that utilize centrifugal force to separate particles from a gas or liquid stream based on their size, shape, and density. Spherical cyclones have a spherical shape and are designed to achieve higher separation efficiency than conventional cyclone separators.

The design of spherical cyclones is based on the principle that the centrifugal force generated by the high-speed rotation of the gas or liquid stream causes the particles to move towards the outer wall of the separator. The particles are then collected at the bottom of the separator by gravity and discharged through a separate outlet. The gas or liquid stream is then discharged from the top of the separator.

Spherical cyclones have several advantages over conventional cyclone separators. First, their spherical shape provides a more uniform distribution of the gas or liquid stream, which results in a more even distribution of the particles. Second, the spherical shape allows for a more efficient use of space, as they can be placed in a compact configuration. Third, the spherical shape allows for easier cleaning and maintenance, as there are no corners or edges where particles can accumulate.

Spherical cyclones can be used in a variety of applications, including the separation of dust and particles from air streams in industrial processes, the separation of solids from liquids in wastewater treatment plants, and the separation of oil and gas from produced water in the oil and gas industry. They are also used in the food processing industry to separate solids from liquids in the production of dairy products and beverages.

One potential disadvantage of spherical cyclones is that they can be more expensive to manufacture than conventional cyclone separators. However, the increased efficiency and other advantages of spherical cyclones often justify the higher cost.

In summary, spherical cyclones are an effective and efficient type of cyclone separator that can be used in a variety of industries for gas-solid or liquid-solid separation. Their unique spherical shape provides several advantages over conventional cyclone separators, including a more uniform distribution of the gas or liquid stream, more efficient use of space, and easier cleaning and maintenance. While they may be more expensive to manufacture, their increased efficiency and other advantages often make them a worthwhile investment.


These vessels are provided with a short bottom outlet. These should be supported on a vessel holder/ holding ring.

To fit a bottom outlet valve (BAL type) all spherical and cylindrical vessels can be supplied with valve seat in bottom outlet. For this, Add a suffix “/B” to the catalogue reference of a vessel, for e.g. ‘VSL50’ should be mentioned as ‘VSL50/B’.


1. Generally, the centre nozzle, referred as DN in all types of vessels, is used for either stirrer fixing or, if stirrer is not fixed, for vapour outlet.

2. The bottom outlet, referred as DN1 in all types, is used for drain. However, in type VSR & VSE, it is also used for fixing immersion heat exchanger.

3. The small side nozzles, referred as DN2 in all types, are used (a) to fix thermometer pocket or

(b) to fix dip pipe for liquid inlet or,
(c) to fix sparger for gas purging or,
(d) to fix vacuum control or vent valve or,
(e) for solid addition.

4. The bigger side nozzle, referred as Dn3, is used for vapour outlet where stirrer is fixed on centre neck. It can also be used for cleaning in case centre neck is used for vapour outlet.

5. Vessels having long bottom outlet, viz VSM, VSPL, VSL, VS etc, can be supported in a heating mantle of heating bath. However, vessels having short bottom outlet, viz VSD, VSCY, VR, VA etc. are to be supported on a vessel holder only. In case of vessels upto 20L size, vessel holding rings can be used instead of vessel holder.
