Mechanical Vapor Recompression Positive Displacement Blower

Mechanical Vapor Recompression (MVR) is a technique increasingly adopted in various industries, distinguished by its multiple uses and considerable benefits.

Design and Features

At the heart of MVR, an ingenious process allows for the mechanical compression of vapor to concentrate and dry various products while achieving significant energy savings. This process also recovers lost thermal heat, contributing to reduced energy costs and environmental impact. By exploiting previously dissipated heat, MVR promotes more eco-efficient production.

Additional Benefits

MVR offers a series of additional advantages. It can capture and reuse thermal energy in chemical reactions, which not only reduces overall energy consumption but also increases the efficiency of industrial processes. Moreover, MVR can compress toxic vapors for safe disposal, thus mitigating health and environmental risks.

Furthermore, the recovery of valuable products from compressed vapors is another major asset. This process minimizes resource losses while optimizing production profitability.

Overall, it is versatile in improving energy efficiency, recovering lost heat, and protecting the environment.

Conclusion

In summary, MVR proves to be a versatile and efficient technique. By improving energy efficiency, recovering lost heat, and protecting the environment, it stands out as an indispensable technology for modern industries seeking to combine performance with sustainability.

The operating principle is simple.

First, the evaporator heats the liquid to concentrate it.

Then, a 'roots' positive displacement blower pulls in and compresses the evaporator's vapor, raising its temperature.

This superheated vapor is sent to a heat exchanger for condensation. The heat from the exchanger warms up the liquid again before it's returned to the evaporator.

This loop generates more vapor.

In this loop, as the vapor is recompressed using mechanical means, its pressure and temperature increase. This increase in pressure and temperature leads to the generation of additional vapor molecules from the liquid phase.

As a result, the system produces more vapor, contributing to the overall efficiency of the process.

Using MVR mechanical vapor recompression, we obtain a concentrated substance. This process significantly reduces liquid effluent volume potentially to zero discharge.

It also minimizes cooling water consumption or eliminates it altogether. Overall, this process loop cuts energy consumption and achieves unmatched energy efficiency.

We offer solutions for customer processes requiring water vapor production ranging from 1,000 to 3,500 kg/h.

We determine the flow rate of the blower based on the available machine size.

When running under pressure, the temperature of the discharged vapor can go up to 115°C, with the incoming steam at 100°C.

When operating under vacuum, the temperature at the suction starts from 85°C, and the steam is discharged at 100°C.

Typical Applications Of Mechanical Vapor Recompression By Hibon:

Hibon process blowers are used in this application to compress the vapors produced by evaporation.

There are numerous references for Hibon process blowers in the chemical industry in ethanol and methanol processes.

In the pharmaceutical industry, MVR - Mechanical Vapor Recompression utilizes Hibon positive displacement blowers (roots type) for distilling pure water and essential oils.

To protect the environment, Hibon has expertise in concentrating:

• residues from polluted soils,
• heavy metals,
• cutting oils,
• radioactive oil,
• printing ink, 
• brine,
• treatment of rubber,
• paint,
• metal rejects. 

In the food industry, lots of factories use PROCESS Hibon blowers to make juices concentrate (such as tomato or fish juice), or to prepare brewing water and salty water.

Seawater desalination processes also use MVR.

Recently, the growing green oil industry has also begun to utilize mechanical vapor recompression processes with rotary lobe blowers.

In an EPR (European Pressurized Reactor) nuclear power plant, mechanical vapor recompression (MVR) is a process used to recover and reuse steam generated during the power generation process.
