SnowPure - Model MVR - Mechanical Vapor Recompression (MVR) Evaporative Technology
Mechanical Vapor Recompression (MVR) is a proven energy-saving evaporative concentration technology, which reduces evaporation energy use by 90% or more. MVR uses energy recovered from the condensate to create a pure liquid distillate and a concentrated product/waste.
From Boyle’s law it is known for a gas that PV/T (Pressure * Volume / Temperature) is constant (PV/T=K). During compression of vapor, the pressure and temperature increase. From this, the heat energy can be reused.
The energy normally lost in the compression is recovered, leading to a highly-efficient evaporation process.
Since this compression is realized by a simple mechanical compressor, the process is called MVR.
- MVR technology uses the generated vapor for heat instead of expensive heat sources
- MVR technology does not require a cooling tower, greatly reducing the use of cooling water
- MVR technology is more efficient than traditional multi-effect evaporation technology saving energy and reducing operating costs
- MVR technology is truly energy-saving, water-saving, environmentally-sound, and helps with resource recycling
- MVR technology achieves low-temperature evaporation, greatly reducing the impact on your material
- MVR technology system structure is simple, fully-automated, with continuous operation
- MVR systems consist of an evaporator, a vapor compressor, separators, pumps, piping, instrumentation, and electrical control components
- MVR systems can be designed around simple evaporators or sophisticated falling film tube evaporators
- MVR systems can use simple vapor compression or sophisticated roots pumps
- MVR systems can have low liquid holdup, or be larger volume tank systems
- MVR systems can achieve a variety of % evaporation, process design and fluid composition will determine this
MVR energy-saving, low-temperature evaporation technology replaces simple evaporators. MVR is widely used in many applications, including:
- ZLD Zero Liquid Discharge for industrial wastewater treatment
- Chemical industry for evaporation, crystallization, and purification
- Salt brine concentration
- RO brine concentration
- Beverage industry (milk, juice, sugar, etc.) concentration
- Food industry (MSG, soy, protein, sugar) concentration
- Pharmaceutical industry (medicines, vitamins) concentration
