Introduction

Atcorp offers Mechanical Vapour Recompressor solutions for industrial processes where waste steam or vapour can be recovered and reused as a valuable energy source. By compressing process vapour and recovering its latent heat, MVR technology can reduce dependence on external steam and improve overall process energy efficiency.

Key Benefits

Energy Recovery
Reduced Utility Costs
Corrosion-Resistant Construction
Lower Steam Consumption
Efficient Vapour Compression
High-Temperature Sealing

Why Choose Mechanical Vapour Recompression?

In evaporation and concentration processes, significant amounts of latent heat can leave with the generated vapour. Mechanical Vapour Recompression captures this vapour, increases its pressure and temperature through compression, and returns it as a useful heating medium. This allows the recovered energy to be reused instead of continuously relying on fresh steam.

An MVR system recovers process vapour and converts its latent heat into reusable process energy.

 

Step 1 – Vapour Generation
The industrial process generates steam or vapour containing useful latent heat.

 

Step 2 – Vapour Collection
The generated vapour is directed toward the MVR suction side.

 

Step 3 – Mechanical Compression
The MVR compresses the vapour, increasing its pressure and temperature.

 

Step 4 – Heat Recovery
The higher-temperature compressed vapour becomes a reusable heating medium.

 

Step 5 – Process Reuse
The recompressed vapour is returned to the process as a heat source.

 

Step 6 – Continuous Energy Recovery
The process repeatedly recycles vapour energy, reducing dependence on fresh steam.

Recover Waste Vapour Energy

MVR technology captures the latent heat contained in process vapour and makes it available for reuse.

 

Reduce Fresh Steam Requirement

Reusing compressed process vapour can significantly reduce the need for externally generated steam.

 

Improve Energy Efficiency

Instead of discarding vapour energy, the system converts it into reusable process heat.

 

Lower Operating Costs

Reduced steam and utility requirements can contribute to lower process operating costs.

 

Corrosion-Resistant Internals

The referenced design uses special corrosion-resistant ENP coating with heat treatment to improve surface hardness and durability. 

 

High-Temperature Sealing

Primary and secondary high-temperature PTFE seals on each shaft help maintain leak-tight operation under demanding conditions. 

 

Enhanced Lubrication

An improved internal lubrication passage and circulation system supports reliable mechanical operation.

 

Process-Focused Configuration

The system can be equipped with desuperheating, instrumentation, condensate collection and control options according to process requirements.

Frequently Asked Questions

Find answers about Mechanical Vapour Recompressors, including how MVR works, energy recovery, applications, construction and system integration.
A Mechanical Vapour Recompressor is a mechanical compressor designed to compress process steam or vapour so that its recovered latent heat can be reused within the process.
MVR recovers the latent heat contained in process vapour and returns the compressed vapour to the process as a heating medium. This reduces the amount of fresh steam or external energy required.
MVR technology is particularly useful in evaporation, concentration and steam-recovery applications where substantial quantities of process vapour are continuously generated.
Conventional systems may continuously consume fresh steam while releasing process vapour. MVR instead recovers and recompresses the vapour, allowing its thermal energy to be reused.
Yes. The MVR configuration can incorporate high-temperature sealing arrangements and an optional oil circulation system for high-temperature applications. The final design depends on actual operating conditions.
They can be configured with corrosion-resistant internal protection. The referenced design includes ENP coating with heat treatment on internal components. Material selection should always be based on the actual vapour composition and process conditions.
Depending on the application, options include desuperheating modules, pressure and temperature transmitters, condensate collection systems, premium-efficiency motors, oil circulation systems and electrical control panels.
Yes, subject to process conditions and available vapour characteristics. A proper assessment of vapour flow, suction/discharge pressure, temperature, heat requirement and existing equipment is required before selecting the MVR configuration.
Yes. Atcorp can help Indian industrial customers evaluate vapour flow, operating pressure, temperature, process requirements and energy-recovery objectives to identify and supply a suitable Mechanical Vapour Recompression solution.
