Read More →As one of South America's most dynamic industrial economies, Chile faces unique challenges that demand highly advanced thermal separation technologies. The country's vast mining sector, particularly in the arid northern regions like the Atacama Desert, operates under severe water scarcity. Consequently, the demand for high-efficiency industrial evaporators has surged, driven by the critical need for water recovery, lithium brine concentration, and Zero Liquid Discharge (ZLD) compliance.
Globally, the industrial evaporation market is undergoing a massive transformation. Driven by stringent environmental regulations and carbon-neutral mandates, manufacturers are shifting away from traditional, steam-heavy multi-effect evaporators toward Mechanical Vapor Recompression (MVR) and waste heat integration systems. These technologies align with Chile's national green transition goals, helping heavy industries minimize their environmental footprint while optimizing operational costs.
In the Salar de Atacama, our customized MVR and Forced Circulation Evaporators are utilized to concentrate lithium-bearing brines. By utilizing mechanical vapor recompression, we help operators achieve high concentration ratios while drastically reducing electricity and steam consumption.
Copper mining operations generate complex, high-salinity wastewater. Our forced circulation crystallization evaporators are designed to handle scaling-prone calcium sulfate and silica-rich streams, recovering pure distillate water and converting dissolved solids into manageable dry solids.
In regions like Biobío, fishmeal production generates large volumes of stickwater. Our falling film evaporators concentrate these protein-rich streams, enabling nutrient recovery and preventing environmental discharge, while preserving the nutritional value of the concentrate.
| Evaporator Type | Primary Heat Source | Energy Efficiency | Fouling Resistance | Best Applications in Chile |
|---|---|---|---|---|
| Mechanical Vapor Recompression (MVR) | Electricity (Compressor) | Ultra-High (COP 10-20) | Moderate (Depends on design) | Lithium brine, large-scale wastewater recovery, starch concentration. |
| Falling Film Evaporator | Steam / Waste Heat | High (Multi-effect configuration) | Low (Requires clean liquids) | Fruit juices, dairy, chemical solutions with low viscosity. |
| Forced Circulation Evaporator | Steam / Thermal Oil | Moderate | Excellent (High shear velocity) | Crystallization, mining tailings, high-fouling wastewater, ZLD. |
