Qingdao Conqinphi Environmental Technology Group Co., Ltd. is proud to present our MVR Evaporator for Chemical Industry, High Salt Concentration Processing. As a leading manufacturer established in 2015 with a factory spanning 10,000-30,000 square meters and a team of 201-300 experienced professionals, we have dedicated ourselves to delivering energy-efficient, reliable evaporation solutions. This MVR evaporator is specifically engineered to handle high-salt wastewater and brine streams in chemical processes, offering up to 60-80% energy savings compared to traditional multi-effect evaporators. Our system is designed to maximize water recovery, minimize waste disposal costs, and ensure compliance with environmental regulations—making it an indispensable asset for chemical plants worldwide.
The core principle of MVR technology is to reuse the latent heat of vapor by compressing the secondary steam, which then serves as the heating medium for the evaporation process. This closed-loop design dramatically reduces steam consumption and operating expenses. Below we provide a comprehensive overview of the product’s features, technical specifications, and benefits.
Key Features & Technology
- High Efficiency Vapor Recompression: Uses a centrifugal or Roots compressor to raise the temperature of secondary steam by 8-15°C, enabling continuous evaporation without external steam supply (except initial start-up).
- Designed for High Salt Concentrations: Handles feed solutions with salt content up to 25% or higher when combined with pre-concentration or crystallization stages.
- Anti-Scaling & Anti-Corrosion Design: All wetted parts are made from SS316L or duplex stainless steel, with optional Teflon coating or special surface treatment to resist scaling and corrosion in aggressive chemical environments.
- Smart PLC Control: Automated operation with real-time monitoring of temperature, pressure, flow rate, and concentration. Remote control and data logging are available for Industry 4.0 integration.
- Compact Footprint: Modular design reduces floor space requirements by up to 30% compared to conventional evaporators.
- Low Operation & Maintenance Cost: Fewer moving parts, simple structure, and long service life (typically >15 years with proper maintenance).

Advantages for Chemical Industry Clients
- Significant Energy Savings: MVR technology reduces steam consumption by 80% compared to single-effect evaporators; electricity consumption is typically 15-30 kWh/ton of evaporated water.
- Zero Liquid Discharge (ZLD) Ready: Can be integrated with crystallizers or dryers to achieve complete solid recovery, meeting the strictest environmental regulations.
- Customizable for Various Chemicals: Suitable for sodium chloride, sodium sulfate, magnesium chloride, ammonium sulfate, and many other high-salt solutions.
- Stable Operation under Fluctuating Feed: Advanced PID control and surge protection ensure stable performance even when feed concentration or flow rate varies.
- Quick Return on Investment: Typical payback period of 1-3 years based on energy savings and reduced waste disposal costs.
- Eco-Friendly: Closed-loop system minimizes emissions and wastewater discharge; contributes to carbon reduction targets.
