Mechanical Vapor Recompression (MVR)

In the modern industrial age, the need to efficiently use and reuse resources is in focus. In order to reduce waste, control emissions and move towards an environmentally friendly way of functioning, you need the right solutions to make it happen. And that’s where Mechanical Vapor Recompression (MVR) comes into play. 

Our Atlas Copco Mechanical Vapor Recompression (MVR) systems use the vapor generated for heat instead of relying on other external heat sources – this method ensures higher energy saving, lower environmental impact and lower overall operational costs. 

Ideal for a number of industries, Atlas Copco MVR recycle the secondary steam energy produced during various processes. Using inhouse technology and expertise, Atlas Copco’s MVR solutions compress low temperature steam, increasing both temperature and pressure. The steam is then engaged into heat transfers for condensation, re-using the steam’s latent heat. 

After first start up, the MVR evaporation process needs no extra steam input. This increases in energy-efficiency by lowering consumption and ensuring significant cost savings, especially when you compare it with traditional single or multi effect evaporators. This solution also ensures reduction in CO2 emissions associated with the process. It’s an effective and highly beneficial solution for range of industries, right from wastewater treatments to the medical industry. The MVR can also be customized according to your specific application demands and environment. 

The Atlas Copco MVR system has pre-engineered and designed modular components allowing efficient commissioning and increased customer value. It’s an innovative and cost-effective upgrade over traditional single and multi-stage evaporators owing to the dramatic reduction in energy wastage and consumption. This one system alone allows you to achieve up to 90% savings and typically allows you to achieve return on investment payback within 2 years. 

Components of the Atlas Copco MVR: 

• VFD operation, matching performance to varying load conditions under different temperatures 
• Heat balance design of pump elements to avoid seizures
• Duplex stainless-steel construction available
• Pumping chamber and rotor design of roots pump suited for handling organic solvent applications with higher efficiency 
• MVR capacity from 20 kg/h to 20,000 kg/h (vaporized mass flow)

• Medical industry applications – MVR aids in efficient evaporation of water, ethanol, methanol and other chemicals in medicine and medical product manufacturing. 

• Beverage industry applications – MVR is used for water evaporation in raw material to deliver better concentration of sugar, juice, milk etc. 

• Wastewater treatments – MVR enables the evaporation process of wastewater to reduce the volume and concentrate it, making it easier and cheaper to dispose. It further enables efficient crystallization of salts like NaCl, Na2SO4, NH4Cl, etc. 

• Distillation processes – MVR is used during distillation of ethanol, methanol, acetone, etc. It helps to recover valuable ingredients from raw materials and from waste produced.
