| Solid/Liquid & Liquid/Liquid |
| CONCEPT : The Separation action of hydrocyclones is based on the effect of Centrifugal forces created within the cyclone body. In contrast to sedimenting centrifuges, however, hydrocyclones have no rotating parts and the necessary vortex is produced by pumping the fluid tangentially into a stationary cono-cylindrical body. In principle, however, each hydrocyclones separates particles of the dispersed phase from the liquid (continuous phase) on the basis of density difference between the phases and the separation depends heavily on particle size. Hydrocyclones are used for both Separation of Solid particles as well as a separation of Liquid from other Liquid; for example, separation of Oil droplets from Water as well as separation of Water droplets from Oil. Motive Power of Hydrocyclone design is the centrifugal force created by the entering Liquid. And therefore two important parameters are velocity of the entering Liquid and radius of the Hydrocyclone. Available pressure drops creates a limitation on entry velocity. Then the size remains the important parameter. Therefore removal of very small solid particles or liquid droplets, smaller hydrocyclone is the design requirement. In such cases a no. of Hydrocyclones are placed in a Cluster. APPLICATIONS :

| INLINE PROCESS |
| Large scale plants have a number of Inline Processes such as Mixing, Homogenization, Dispersion, Aggregation, Flocculation, Emulsification, Deaeration, Suspension, Blending, Micromixing, Extraction, Aeration, Agglomeration, Reactions and Heat Transfer. Mamko has a number of 'Products' to efficiently perform these processes. Get a Datasheet by clicking here and fill it up for your needs by selecting a product below : |
Eductors are valuable forSump Clean-upswith water or sea water as driving force. In Ships they are very useful as there is an individual supply of driving force.
These are also useful to take waterout of deep wellswhere ordinary pumps with foot valve suction arrangement fail.
Eductors are especially useful in clean-ups of emergencyspillsas they can be operated from any position and, at a long distance and also as they are self priming

| Eductors are effectively used to mix solid powders and transport them to a Blender and Reactor. |
| 'Separation' is an important operation in the process Industry. Mamko offer Services where the separation is only dependent on 'Physical forces'. Therefore we do not deal with 'Distillation', 'Absorption' and 'Adsorption'. From the list below you may select and fill up the 'Datasheet' and send your enquiry. |
| In Tank Processes are common in Process Industry. Mamko offers several choices of designs for Low viscosity Liquids to high viscosity materials (or non-Newtonian Liquids). Further Mamko also offers a large number of options to Agitated Vessels. Depending upon, the Application, the Process, Tank Geometry and the Properties of liquids, gases and solid Powders , selection shall be made.

| Jet Mixing can also be used judiciously for Inline Mixing. There are some situations where Inline Jet Mixer could be preferred over Static Mixers. |
If one of the Liquid has sufficiently high pressure and if there is not enough space for a Mixer a Standard Jet Mixing arrangement could be used as shown above. Here the ratio of Flow Rates of the Mixing Liquids plays an important role.
When the Mixing Liquids viscosities have a large difference that is their ratios are either very high or very low a preferred arrangement is as shown as given below
| A situation where the density difference in two liquids is high and one invariably settles in at the bottom of a horizontally laid pipe, an arrangement shown below is useful. A typical example of this is Crude Oil flow from an Oil Well to the Tank Farm |
| Mamko have sufficient knowledge of Jet Mixing to enable them to designInline Jet Mixersas per the process requirement. |
Jet mixing in tanks is usually used either to blend a fresh feed in with the contents of a tank or to obtain a homogeneous mixture within the tank. Batch or Continuous operation is possible and a side entry (i.e. through the tank wall) or an axial jet (i.e. along the axis of the tank) may be used. The Jet is positioned either near the tank floor pointing towards the liquid surface or near the liquid surface pointing towards the tank floor. Jet Mixers are designed specific. The Jet is designed to create appropriate velocities. It is then positioned in the tank at a right position and with a correct angle so that appropriate swirl and vortex is created for the bulk mixing. In some situation more than one jet are required.
Industrial Application of Jet Mixing are :
The Eductor principle whereby high velocity of one fluid creates suction and attracts the second liquid towards itself to effect micro mixing is combined with the JET mixing which is essentially bulk mixing to produce Eductor JETS. Eductor Jets are also effectively used to doze a second liquid into the bulk without an extra pump.
| Inline High Shear Mixers / Emulsifier |
| High Shear Mixers are operated at high speeds more than 1000 Rpm with smaller Impellers and has typical design. The concept of High Shear Mixing is detailed in In Tank Processes. This can also be used Inline as shown below. |
(For Emulsions, Slurries and Pastes)
CONCEPT OF HIGH SHEAR MIXING
A high shear zone is created in and around the impeller. These impellers are carefully designed to suit the application and the physical properties of the materials. For example, in case of emulsification the liquids are forced through an extensional flow stream followed by a physical shearing. The liquid is mixed in the bulk by the flow field created by the impeller and sheared in the specially created zone. The best results are thus achieved.
MAMKO have 39 Impeller Designs.
| Gas (Vapour) Liquid Seperator (Knockout Seperator) |
Knockout Separator is basically a vapor Liquid Separator, designed mainly on Hydrocyclone principle. It is constructed similar to Hydrocyclone with a Liquid collected at the Bottom. The outlet at where vapor goes upwards may be connected to suction of a blower or to a vacuum.
Eductor when designed appropriate are able to create full vacuum. They are thus very useful in Chemical Industry where clean vacuum is required.
CONNECTIONS
Eductors may be supplied in any connections as suitable to the application. They may be flange or thread connected on to clamp hose pipe.
Eductors utilize Kinetic Energy of one Liquid to pull another mix with it and convey it further up. The high pressure of one pump is converted into the Kinetic Energy and high velocities. The suction caused thereby pulls the other Liquids for the the further action
There are several uses of Eductors such as:
LMEs are used for suction of Gas to form small Bubbles in Gas Liquid operations.
They are useful when one Liquid is available at high pressure and it has to mix with another which is without a pump or having a low discharge pressure pump
| Line Mixing Eductors are used to prepare hot water with use of low pressure steam. |
| Cavitators / Mechanical Emulsifiers |
These are specially designed Static Mixers for the process of Emulsification in-line. Whereas 'Mechanical Emulsifiers' spread the emulsification process over a length, 'Cavitator' achieves it at a short length.
These are generally high pressure drop devices. The pressure drop range from 5 bar to 100 bar. The first criterion is the required range of droplet size; 5 to 10 micron or 10 to 50 micron or 50 to 200 micron. There are important parameters such as physical properties of continuous phase and dispersed phase. The physical properties required are: Viscosity, Density and Interfacial Tension at the operating temperature.
Depending upon the chemical properties of Liquid Material of Construction (MOC) shall be suggested. For Mechanical Emulsifier MOC is genrally SS304 or SS316. For Cavitator these materials are especially hardened to take care of erosion at high velocities.
