    Multi Effect Mvr Falling Film Vacuum Evaporator Sodium Chloride Salt Line

    Multi-Effect MVR Falling Film Vacuum Evaporator — Sodium Chloride Salt Line
    Multi-effect MVR falling-film vacuum evaporator line for sodium chloride refining

    Engineer-to-order multi-effect falling film evaporator integrated with MVR (Mechanical Vapor Recompression) for sodium chloride (NaCl) refining lines. Operating under vacuum, the hybrid MEE+MVR train achieves high thermal efficiency, precise supersaturation control, and continuous crystal quality for edible and industrial salt production.

    Key Benefits
    • Energy efficiency: MVR recycles latent heat; multi-effect staging lowers specific energy use and fresh steam demand.
    • Crystal quality: Controlled nucleation/growth delivers narrow size distribution for table, fine, or coarse grades.
    • Stable vacuum duty: Falling film with low ΔT preserves heat-transfer coefficients and limits fouling.
    • Food-grade compliance: 316L/duplex materials, drainability, CIP-ready design supporting HACCP/ISO.
    • Line integration: Seamless tie-in with brine purification, centrifugation, drying, sizing, iodization, and packing.
    Process & Thermal Economy

    Secondary vapor is mechanically recompressed and reused as the primary heating medium, while upstream/downstream multi-effect falling film effects cascade energy. Tight control of ΔT/LMTD, residence time, and recirculation stabilizes supersaturation for repeatable NaCl crystallization and low OPEX.

    Materials & Hygiene

    Wetted parts in SS316L/duplex (Ti/Hastelloy on request), sanitary finishes, sloped/drainable piping, validated CIP, and material traceability for food-contact applications.

    Process Overview — Refined NaCl Line
    Flow: brine make-up/purification → multi-effect + MVR falling-film evaporation → crystallization → centrifugation → drying/sizing → iodization/packing
    • Brine make-up & purification: dissolving, softening (Ca/Mg removal), clarification/filtration, polishing.
    • Multi-effect + MVR evaporation (vacuum): staged effects with recompressed vapor to drive heat duty.
    • Crystallization control: supersaturation setpoints for target grain bands (fine/table/coarse).
    • Solid–liquid separation: peeler/pusher centrifuge; mother liquor recycle.
    • Drying & sizing: fluid-bed/vibratory drying; sieving/polishing to spec; optional iodization & anti-caking.
    • Packing: retail (1 kg) to bulk (25–50 kg) with weight checks and metal detection.
    Key Components
    • Multi-effect falling film evaporator bodies with preheaters/condensers
    • MVR compressor (turbo/Roots) with VFD for ΔT/capacity control
    • Vapor–liquid separator, main heater, vacuum/NCG handling system
    • Brine purification skid (dissolver, softening, clarification, filtration)
    • Peeler or pusher centrifuge; fluid-bed/vibratory dryer; sieving/polisher
    • PLC/HMI/SCADA, instrumentation (T/P/flow/cond/level), historian & remote access
    • CIP skid; iodization and anti-caking dosing modules
    Performance & Sizing
    ParameterTypical Target / Range*
    NaCl purity (dry)≥ 99.2% (up to 99.7% with enhanced purification)
    Moisture (final)≤ 0.2% (grade-dependent)
    Crystal sizesFine 0.2–0.5 mm; Table 0.5–1.2 mm; Coarse 1.2–2.5 mm
    Line capacity5–500 t/day (modular trains)
    Electric use (MVR)~15–40 kWh per ton H₂O evaporated
    Fresh steam demandVery low after start-up (backup/ancillary only)
    Campaign length≥ 10–20 days between CIP (feed-dependent)

    *Performance depends on feed composition, scaling tendency, compression ratio, and heat-exchange area.

    FAQ
    Why combine multi-effect with MVR?

    The hybrid layout merges the low utility demand of MVR with the thermal economy of MEE, balancing CAPEX and OPEX.

    Can you supply food-grade documentation?

    Yes—material traceability, surface finish records, and CIP validation support HACCP/ISO 22000 programs.

    What product grades are supported?

    Fine, table, and coarse salt with optional iodization and anti-caking, plus industrial grades on request.

    Application
    Applications: refined edible salt, industrial NaCl, brine upgrading with hybrid MEE+MVR
