    Tubular Type Exchanger Forced Circulation MVR Evaporator

    Tubular Type Exchanger · Forced Circulation MVR Evaporator
    Tubular shell-and-tube MVR evaporator with forced-circulation loop and mechanical vapor compressor

    Engineer-to-order tubular (shell-and-tube) MVR evaporator with a forced-circulation loop for high-salinity, viscous, and solids-bearing feeds. Mechanical Vapor Recompression (MVR) recycles latent heat as the primary duty, delivering low OPEX, robust heat transfer, and stable 24/7 operation for chemical, food, and environmental services.

    Key Benefits
    • Rugged thermal core: Tubular exchangers tolerate scaling/erosion better than narrow-gap plates.
    • Stable with solids: High-velocity forced circulation maintains ΔT/LMTD and limits deposition.
    • Energy saving: Electric-driven MVR minimizes fresh steam after start-up.
    • Wide duty window: Fits concentration, mother-liquor recovery, and ZLD pre-crystallization.
    • Serviceability: Straight/U-tube bundles, large clean-outs, CIP-ready design.
    Process & Thermal Economy

    Secondary vapor is mechanically compressed to elevate saturation temperature and reused as the heating medium. The forced-circulation loop provides high shear at tube walls, protecting heat-transfer coefficients across variable chemistry and viscosity while keeping specific energy low.

    Materials & Cleanability

    Wetted parts in SS316L/duplex; titanium/Hastelloy options for chloride or aggressive feeds. Drainable layouts, removable channel heads, CIP skid, and antiscalant dosing extend campaign length.

    Process Overview — Tubular FC MVR
    Flow: feed conditioning → tubular heater (forced circulation) → MVR compression → condensate polishing → concentrate handling
    • Feed conditioning: screening/filtration, softening or pH trim to mitigate scaling/corrosion.
    • Tubular heater + separator: high-velocity loop under vacuum for efficient, gentle evaporation.
    • MVR compression: VFD-driven compressor sets discharge pressure (ΔT) and capacity.
    • Condensate polishing: filters/RO/AC to reuse or compliant discharge (conductivity/TOC guard).
    • Concentrate routing: to crystallizer/centrifuge/dryer or recycle per ZLD/production needs.
    Key Components
    • Tubular shell-and-tube heater (straight/U-tube) with forced-circulation pump
    • MVR mechanical vapor compressor (turbo/Roots) with VFD
    • Vapor–liquid separator, surface condenser, vacuum/NCG handling skid
    • Preheaters/heat-recovery HX; PLC/HMI/SCADA with historian
    • CIP skid; antiscalant dosing; instrumentation (T/P/flow/cond/level)
    Performance & Sizing
    ParameterTypical Range*
    OperationContinuous, vacuum duty
    Electric use (MVR)~15–40 kWh per ton of water evaporated (duty/CR dependent)
    Shell pressure~6–25 kPa(abs), feed/ΔT dependent
    Turndown50–100% with stable ΔT and quality
    MaterialsSS316L / duplex; Ti/Hastelloy on request

    *Performance depends on feed salinity/viscosity, fouling tendency, compression ratio, and exchanger design.

    FAQ
    When choose tubular over plate/pillow plate?

    For scaling, particulates, or erosion risk, tubular exchangers provide higher robustness and allow mechanical cleaning.

    Can it integrate into our ZLD train?

    Yes—commonly paired with RO/NF upstream and crystallization/solids handling downstream.

    How is scaling managed?

    Optimized ΔT/LMTD and velocity, antiscalant dosing, scheduled CIP, and corrosion-appropriate materials (e.g., Ti for chlorides).

    Application
    Applications: high-salinity concentration, viscous feeds, and ZLD pre-crystallization with tubular forced-circulation MVR
