Copper Sulphate Crystallization and MVR-Copper-

MVR (Mechanical Vapor Recompression) evaporation technology for copper sulphate crystal is noticeably advantageous in energy conservation, reducing energy cost by 3/4 compared with conventional two-effect evaporator. The key point is that the secondary steam can be recycled after enthalpy increase by mechanical compression, greatly decreasing the demand of fresh steam and
