Product Description
Titanium MVR Evaporation System for NaCl Crystallization
The Titanium (Ti) MVR evaporation and crystallization system is engineered specifically for table salt and industrial salt production. By mechanically recompressing and reusing latent heat, this system significantly reduces specific energy consumption and fresh steam requirements while delivering consistent crystal quality with narrow size distribution.
Key System Advantages
- Significant energy savings: Primarily electric-driven with fresh steam used mainly during start-up or for trim under extreme conditions
- Superior chloride corrosion resistance: Titanium (Gr.2/Gr.12) on critical heat-transfer and pressure parts minimizes pitting and crevice corrosion
- Consistent crystal quality: Controlled supersaturation and residence time yield uniform NaCl crystals
- Extended operational campaigns: Sanitary design and CIP capabilities shorten downtime and extend heat-exchanger cleanliness intervals
Energy Performance
Typical power consumption ranges from 15-35 kWh per ton of water evaporated, depending on compression ratio, temperature differential, and heat-transfer area. The system greatly reduces cooling water and boiler load requirements.
Crystal Quality Control
Forced-circulation crystallizer maintains stable heat-transfer coefficients and slurry density, producing a tight particle size distribution ideal for table-salt fractions.
Material Reliability
Titanium tube bundles and Ti-clad plate exchangers handle critical duties, while duplex stainless steel may be used for structural frames to optimize cost efficiency.
Process Flow Overview
- Brine make-up & purification: Dissolution → softening (Ca/Mg removal) → coagulation/clarification → polishing filtration
- Preheating & de-aeration: Stabilizes driving force and reduces corrosion/foaming
- MVR forced-circulation evaporation & crystallization: Compressed vapor returns to shell side with supersaturation and slurry density control
- Solid-liquid separation: Peeler or pusher centrifuge removes mother liquor with recycling to increase overall yield
- Drying & classification: Vibrating/fluid-bed drying → screening → polishing to achieve target size bands
- Iodization & anti-caking: In-line dosing and mixing to meet regulatory requirements
- Packing: Flexible packaging from 1 kg retail to 25-50 kg bags or bulk with metal detection and weight control
