Storage Tank Mixing
Mixing is one of the crucial and important unit operation in almost al the tanks in Storage Terminals and Tank farms. This is required to ensure that there is no settlement , stratification of the liquids thereby resulting in uniform homogeneity levels at all the locations in the tank. One of the key factor for this application is ability of the mixer to handle various fluids with different transport properties.
Mixrite Jet Mixers are designed specifically for the above application and are tailor made to suit Tank Geometry and transport properties of different liquid to be handled. In some cases , the Jet Mixers can designed taking into account the specifications of existing Recirculation Pump so that no major modification have to be done to existing installation. The Homogenization and/or Blending time of storage tank can be reduced substantially with the aid of Jet Mixer when applied on recirculation discharge line. Single or Multiple Jet Mixers are installed depending on the volume to be handled and the transport properties of the fluids in consideration.
The velocity difference between the jet and the secondary liquid creates a mixing layer of jet boundary. This mixing layer grows in the direction of jet flow, entraining / mixing the bulk liquid into the jet. The Recirculation Pump Discharge is pumped through a header into one or multiple jet mixers submerged within the tank depending on the tank geometry. The static pressure at the entrance of the nozzle is converted into kinetic energy by allowing the fluid to flow freely through a convergent type nozzle. As the operating fluid exits the nozzle, it entrains liquid from the tank through the suction chamber.
The operating liquid along with entrained liquid then undergoes thorough mixing in the parallel section of the diffuser. The divergent portion of the diffuser helps in converting the velocity head to pressure head at the discharge end of the mixer. The discharge flow continues the mixing action of the liquid and imparts uniform mixing throughout the tank.
• Simple And Compact In Construction.
• Low Capital And Operating Cost As Compared To Conventional Agitators.
• No Moving Parts And Hence Maintenance Free.
• Easy To Install.
• High Energy Efficiency.
• Designed To Have Practically No Dead Spots In The Tank.
• High Degree Of Operational Safety.
• High Degree Of Mixing Per Unit Of Expended Energy.
Mixrite Jet Mixers designed for Storage Tanks delivers excellent level of homogeneity within the tank. As these mixers are designed to suit the existing Pump, it is very easy to retrofit Jet mixers in existing storage tanks without making major modification. The mixers have no moving parts and hence require no attention once they are installed.
