Mechanical Vapor Compression/Recompression (MVR)
Thermal Vapor Compression/Recompression (TVR)
Vobis Mechanical Vapor Compression/
Recompression
Mechanical Vapor Compression or Recompression (MVR) can be implemented with our single or multiple effect Falling Film Evaporator Systems or our Forced Circulation Evaporator Systems.
This enables low temperature operation under vacuum operating conditions and accommodates heat sensitive materials. The systems also have low energy consumption and can eliminate cooling water as a necessity for condensation. Heat from the condenser is recovered rather than lost and utilized in the evaporation process.
How Our MVR Evaporators Work
Vobis evaporators with Mechanical Vapor Recompression (MVR), also known as Vapor Compression Evaporators (VCE), operate via an electrical heat pump, fan or blower principle. Water or another volatile component is evaporated, and subsequently the vapor is recompressed mechanically by a highly efficient compressor, fan, or blower, increasing its saturation temperature and releasing its latent heat.
Further Considerations
Our vapor compression evaporation systems are manufactured in a wide variety of materials of construction of the process wetted components, dependent upon the application requirements. Appropriate materials can include various stainless steels, Duplex steels, and titaniums.
Allen Bradley or Siemens PLC control systems are typically implemented to accurately and reproducibly control our mechanical vapor recompression evaporation systems.
Skid mounting or Modularization allows easy installation as well as ready access to all piping, control elements, pumps and process vessels.
Advantages of Our MVR Evaporation Systems
Vobis Vapor Compression Evaporators or MVR evaporators are more energy efficient than multiple effect evaporators alone and are thus more operationally cost-effective due to the very high efficiency of the electrical compressor, blower and/or fan that is implemented at the heart of the system providing the energy for evaporation.
Only electrical energy is needed; neither steam nor cooling water is required during operation, so these systems can be implemented where steam is unavailable. Unlike thermal vapor compression evaporators, mechanical compressors eliminate the need for any steam once the system is operational.
Our VCE (MVR) production systems can utilize either single or multiple effect falling film or forced circulation plate evaporators which have the added advantage of requiring only a small product inventory.
Thermal Vapor Compression/
Recompression (TVR)
Thermal Vapor Recompression (TVR) or Thermal Vapor Compression can be implemented with our single or multiple effect Falling Film Evaporator Systems or our Forced Circulation Evaporator Systems for energy conservation. Incorporating Thermal Vapor Recompression requires steam for the operation of a thermal vapor compressor. The compression of steam results in heat recovery which is utilized in heating the system. This can often offset the need for an additional evaporator stage.
How Our TVR Evaporators Work
In Vobis Evaporation systems utilizing Thermal Vapor Recompression, high pressure steam is used to compress vapor from the evaporator which is then condensed in the heat exchanger. Primarily applied to a single effect evaporator or in the first effect of a double or triple effect system.
Further Considerations
Thermal Vapor Recompression is integrated in an evaporator system when the reduction of energy consumption is a primary goal.
Much like Mechanical Vapor Recompression (MVR), Thermal Vapor Recompression enables low temperature operation under vacuum operating conditions and protects heat sensitive materials.
The steam requirements for an evaporator system with Thermal Recompression is much less than a system without it, often eliminating the need for another effect, and thus increasing the system’s cost effectiveness.
Allen Bradley or Siemens PLC control systems are typically implemented to accurately and reproducibly control our mechanical vapor recompression evaporation systems.
Skid mounting or Modularization allows easy installation as well as ready access to all piping, pumps, control elements, and process vessels.
