Product Description
Multiple Effect MVR Dimple Plate Evaporator for Pulp Black Liquor
This advanced evaporator system is specifically designed for processing black liquor in paper production facilities, enabling efficient chemical recovery and steam generation while reducing operational costs.
Black Liquor Processing
Black liquor is a by-product from pulp mills containing lignin, hemicellulose, sodium hydroxide (NaOH), and sodium sulfide (Na2S). According to the International Energy Agency, black liquor represents the fifth most important fuel source globally, with significant potential for biofuel production.
Multiple Effect Evaporation Technology
Our system connects multiple evaporators in series, where only fresh steam is added to the first effect. The generated secondary steam then serves as heating steam for subsequent effects, dramatically reducing both heating steam consumption and cooling medium requirements.
Key System Advantages
- Electric-powered MVR system with energy consumption of only 2.2kWh per ton of water evaporation
- Minimal fresh steam requirement - only for initial pre-heating
- No independent condenser needed, eliminating circulating cooling water requirements
- Small temperature difference enables moderate evaporation, improving product quality and reducing fouling
- Precise temperature control suitable for heat-sensitive products

Falling Film Evaporation Technology
Our falling film evaporator efficiently cools liquids to as low as 0.5°C with high-performance heat exchange and reliable operation. The laser-welded heat transfer plates create optimal turbulent flow for maximum efficiency.
Application Industries
Cold storage for agricultural products, poultry processing, food and dairy processing, seafood processing, meat processing, beverage industry, and concrete cooling applications.
Advanced Laser Welding Technology
Heat transfer plates are manufactured using automated laser welding processes, creating a special pillow structure that ensures optimal fluid turbulence, high heat transfer efficiency, and resistance to fouling and high temperatures.
