    High efficient Double effect crystallization system for multiple salts

    High-Efficient Double-Effect Crystallization System for Multiple Salts
    Hanpu designs and supplies double-effect evaporation & vacuum crystallization systems for multi-salt applications such as NaCl, KCl, (NH4)2SO4, Na2SO4, sodium acetate, and mixed brines. Our compact two-effect layout delivers strong energy savings, precise crystal size control, and reliable operation for both new plants and brownfield upgrades.
    Technology Parameters
    ModelDE-500DE-1000DE-1500DE-2000
    Evaporation (kg/h)500100015002000
    Steam Consumption (kg/h)≤250≤500≤750≤1000
    Dimensions L×W×H (m)4×1.5×3.35×1.6×3.56×1.6×3.76.5×1.7×4.3
    Cycle Water Consumption (t/h)6121518
    Operating Ranges (common to all models)
    Evaporation Temperature — First Effect (°C)80–90
    Evaporation Temperature — Second Effect (°C)55–70
    Vacuum — First Effect (MPa)0.02–0.04
    Vacuum — Second Effect (MPa)0.05–0.06
    Steam Pressure (MPa)<0.25
    Concentration Ratio1.2–1.3
    Energy Efficiency
    Typical steam economy of ~1.8–2.2 kg water/kg live steam (higher with TVR), cutting utility cost vs. single-effect systems.
    Crystal Quality
    Tight control of supersaturation, magma density, residence time, and seeding to hit target PSD and purity.
    Low Fouling & Easy CIP
    Optimized velocities and heat flux reduce scaling on heat surfaces; automated CIP quickly restores U-value.
    Flexible to Multiple Salts
    Process recipes switchable for chloride, sulfate, phosphate, and acetate systems; compatible with upstream RO/NF and downstream centrifuges/dryers.
    How the Double-Effect Crystallization Works
    1. Preheat & Deaerate: Feed is preheated using condensate/flash vapors; non-condensables removed to stabilize boiling points.
    2. Effect 1 (Higher T/P): Falling-film or forced-circulation evaporation raises concentration near the metastable zone.
    3. Effect 2 (Lower T/P, Vacuum): Secondary vapor from Effect 1 heats Effect 2; controlled flash cooling and/or evaporative cooling develop supersaturation.
    4. Crystallizer: OSLO/FC or draft-tube-baffle configuration manages magma density and growth, limiting fines.
    5. Solid–Liquid Separation: Centrifuge or pressure filter recovers crystals; mother liquor is recycled or purged based on impurity build-up.
    6. CIP & Turnaround: Automated alkaline/acid cycles with conductivity endpoints; short downtime between campaigns.
    Delivery Workflow
    Feed analysis & targets → Thermal design & heat/mass balance → Pilot validation (as needed) → Detailed engineering → Fabrication & FAT → Installation & commissioning → Performance testing & training → Lifecycle service & spares.
    Performance figures are indicative. Final design is confirmed by laboratory data, BPE/viscosity curves, corrosion/scaling assessment, and site utility conditions.
