Tubular Type MVR Evaporator System Exchanger Forced Circulation 480V

Tubular Type MVR Evaporator System Exchanger — Forced Circulation · 480V
Tubular MVR evaporator system with shell-and-tube exchanger, forced circulation, 480V power

Engineer-to-order tubular (shell-and-tube) MVR evaporator with forced circulation for high-salinity, viscous, and solids-bearing streams. A mechanical vapor compressor recycles latent heat as the main duty, while tubular exchangers deliver robust heat transfer and fouling resistance. Designed for 480 V grids with fully automatic 24/7 operation.

Key Benefits
  • Durable heat exchange: Tubular exchangers tolerate scaling/erosion better than plates on difficult feeds.
  • Stable with solids: High-velocity forced circulation maintains ΔT/LMTD and limits deposition.
  • Low OPEX: Mechanical vapor recompression minimizes fresh steam after start-up.
  • Wide duty window: Configurable for concentration, mother-liquor recovery, or ZLD pre-crystallization.
  • Easy maintenance: Straight-tube or U-tube bundles, clean-outs, and CIP-ready design.
Process & Thermal Economy

Secondary vapor is mechanically compressed to elevate saturation temperature and reused as the heating medium. Forced-circulation loops keep tube wall shear high, protecting heat-transfer coefficients across variable chemistries.

Electrical Integration — 480V

Low-voltage integration for 480 V / 60 Hz (50–60 Hz configurable). VFD-driven compressor and pumps, soft-start, and optional AFE/harmonic filters for grid compliance. MV transformers available on request.

Materials & Cleanability

Wetted parts in SS316L/duplex; titanium/Hastelloy options for chloride/corrosive service. Drainable layouts, removable channel heads, CIP skid, and anti-scale dosing for long campaigns.

Process Overview — Tubular MVR
Flow: feed conditioning → tubular heater (forced circulation) → MVR compression → condensate polishing → concentrate handling
  • Feed conditioning: screening/filtration, softening or pH trim to reduce scaling/corrosion.
  • Tubular heater + separator: high-velocity loop under vacuum for gentle, efficient evaporation.
  • MVR compression: compressor discharge sets ΔT; shell vacuum defines boiling point.
  • Condensate management: polishing (filters/RO/AC) for reuse or compliant discharge.
  • Concentrate routing: to crystallizer/centrifuge/dryer or recycle per flowsheet/ZLD.
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, condenser, vacuum/NCG handling skid
  • PLC/HMI/SCADA; instruments (T/P/flow/cond/level); historian & remote access
  • CIP skid; anti-scale dosing; optional condensate polishing filters/RO

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

FAQ
When choose tubular over plate/plate-and-frame?

Tubular exchangers are preferred for scaling, particulates, or erosion risk—offering higher robustness and easier mechanical cleaning.

Can it integrate into our existing ZLD train?

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

How is scaling managed?

Optimized ΔT/LMTD and velocity, anti-scale dosing, scheduled CIP, and materials upgrade (e.g., Ti) for aggressive brines.

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