Thermal Vapor Recompression (TVR)
Thermal Vapor Recompression (TVR) improves the energy efficiency of evaporation processes by reusing process vapor as a heat source. By reducing the demand for live steam and cooling water, TVR can significantly lower operating costs while maintaining gentle evaporation conditions and enabling the use of low-pressure steam.
Thermal Vapor Recompression (TVR)
How it works
Thermal vapor recompression uses part of the process vapor to heat the evaporator. The other part is passed on to the next stage or converted into condensate.
Steam compression for heat recovery takes place in a steam jet compressor, which is usually designed for a specific operating point. Motive steam (live steam) is required to operate a thermal vapor recompressor.
