Kemai Group is one of China largest rubber additives from China. They are raw material supplier for Michelin, Bridgestone etc. During the production of rubber additives, wastewater treatment is a big problem. In order to provide customized solution to Kemai group, our company did long term discussion in technical achievement and cost performance investment around 2013. Till now, Kemai Group has bought 8sets MVR Evaporator system from LH Evaporator Company in Tianjin site and Inner Mongolia site. 3sets have been working for 2~3years, the fourth set just complete the installation and trail operation.
From Monday of this week, the MVR team including project dept., processing dept., equipment dept., electrical dept., instrument dept., work together totally 72hours, the trail operation is very successful. The average evaporation capacity reaches the target and the MVR Evaporator matches well with the pretreatment systems. The turnkey solution for the rubber additives waste water including:
- Multi process of wastewater for pre-treatment
- Two stage MVR Evaporation and crystallization
- Final Further treatment
The two stage MVR Evaporation system mainly including: 2set evaporation heat exchanger, 2set vapor liquid separator, 2set vapor compressor etc.
MVR means Mechanical vapor Recompression. The technology is transfer the low temperature & low pressure vapor to high temperature & high pressure vapor, and then the secondary vapor can be reused to heat the raw material liquid for evaporation. With MVR Evaporator, once the system started and preheated, only small amount of fresh vapor is required to supply to the evaporator system. Vapor compressor is the key equipment to achieve the MVR technology. Our company has the technology for evaporator & vapor compressor, can offer the complete solution.
