Benefit of a Vertical Dry Vacuum Pump when using a Reactor

The Standard Group of Companies design and manufacture a range of Automated Vertical Dry Vacuum Pumps (ADVV) in standardised and bespoke designs.

These pumps are manufactured in our Stanpumps division in Hyderabad, India.

These Vertical multi stage dry lobe and claw (300 m3/hr) pump solutions are ideal for Reactor Solvent Extraction applications and have been successfully installed in hundreds of applications in the Pharmaceutical sector.

Solvent extraction is one of the most common and important methods for separation and purification of many elements.

Solvent extraction has always proved itself very helpful as a recovery method for many components. This method of separating compounds on the basis of their solubility as with two different immiscible liquids.

The process is also a method of separating a compound which is soluble in an immiscible liquid which gives you a desired compound either in the form of a solute or a type of residue. Using solvents in any manufacturing process requires the following:

  • Charging
  • Removal
  • Storage.

Each stage creates solvent vapours in addition to those that are generated when the solvents are physically used in the manufacturing process.

In the Pharmaceutical sector solvents, which are used in the reactors are typically displaced through a vent system to a solvent recovery system.

In the reactors more efficient and economical method of solvent recovery is to use a “closed-loop” system.

A closed-loop system is best suited for batch processing systems, but can also be adapted to a continuous feed system.

The closed-loop system has the advantage of having no emissions during operation, which in effect gives a 100% recovery of the solvent.

The most common closed-loop system employs a vacuum pump for handling solvents.

There are many industrial applications which involve the processing of solvents. Such applications include;

  • Distillation
  • Drying
  • Evaporation
  • Filtration

Recovering these solvent vapours is critical for:-

  • Process efficiency
  • Plant cost savings
  • Operator health & Safety
  • Safety Legislation compliance.

The Stanpumps ADVV creates an ideal operating environment for 100%, closed loop solvent extraction and recovery, as found in Reactor processing.
