Product Description
MVR Evaporators for inorganic salt mother-liquor reduction are engineered to cut disposal volume, recover reusable water and valuable salts, and lower energy bills for crystallizer mother liquors and high-TDS process streams.
Inorganic salt production often leaves large volumes of mother liquor with high TDS, high boiling point elevation (BPE), and severe scaling tendencies. Traditional thermal methods depend on costly steam and vast utility capacity. Our MVR-centered EPC/turnkey solutions bring factory-grade control to evaporation and concentration, delivering electricity-driven heat recycling, compact layouts, and reliable anti-fouling performance.
Key Advantages
- High Volume Reduction - Reduce disposal volume by 70-95%, enabling ZLD or near-ZLD targets
- Energy Efficient - Electrical SEC typically 8-20 kWh/m³ evaporated; lower OPEX vs. steam-only systems
- Anti-Fouling Design - Forced-circulation, optimized ΔT (≈3-8 K), demister & NCG management for long runs
- Right Materials - 316L / 2205 / 904L / Ti / Hastelloy per chloride & corrosive load; proven for brines
EPC/Turnkey Delivery Benefits
- Measurable Cost Reduction: MVR electrification replaces fresh steam; typical utility savings vs. single-effect steam are 30-60%
- Water & Salt Recovery: Recover reusable condensate water and route concentrated brine to crystallization for saleable salts or safe disposal
- Stable, Clean Operation: CIP-ready layouts, velocity windows, and entrainment control secure compressor reliability and product consistency
- Compact & Retrofit-Friendly: Modular skids shorten installation and minimize production downtime
Delivery Workflow
Feed & BPE Analysis → Process Design & Simulation → Pilot / Bench (optional) → Detailed Engineering → Fabrication & FAT → Installation & Commissioning → Performance Test & Training → O&M / Spares / Remote Support
Typical Design Specifications
| Parameter | Specification |
|---|---|
| Operating Temperature / Pressure | ~60-90 °C under ~20-80 kPa(abs), product & BPE dependent |
| Temperature Lift (ΔT) | ~3-8 K across calandria (smaller ΔT → higher COP & cleaner surfaces) |
| Heat Exchanger | Falling-film for cleaner feeds; Forced-circulation for fouling/viscous or crystallizing duties |
| Electrical SEC | ~8-20 kWh per m³ evaporated (≈0.03-0.08 kWh/gal), site-dependent |
| Materials | 316L / 2205 / 904L / Ti / Hastelloy as required by chloride/corrosion |
* Ranges are typical; final design depends on your feed composition, BPE curve, fouling/foaming tendency, utilities and product specs.
Applications
- Sodium Sulfate / Glauber's Salt Mother Liquor - pre-concentration and recycle to crystallizers
- Sodium Chloride / Vacuum Salt Lines - brine concentration and mother-liquor reduction ahead of centrifuge & dryer
- Soda Ash / Chlor-Alkali - high-chloride brines with anti-fouling forced-circulation designs
- Phosphate / Fluoride-Bearing Liquors - materials upgrade and condensate polishing options
- Potash & Mixed-Salt Systems - hybrid MVR+MEE integration and crystallizer coupling
- RO Reject / ZLD Brines - volume minimization and water reuse
Frequently Asked Questions
Q1: How do you prevent scaling (e.g., CaSO₄, silica) inside the heater?
We combine forced-circulation velocities, optimized ΔT, demister/entrainment control, and tailored CIP regimes (alkali/acid). For crystallizing duties we separate crystal growth in a downstream crystallizer rather than inside the main exchanger.
Q2: Why choose MVR over MEE for mother-liquor reduction?
MVR recycles its own vapor using electricity, typically lowering utility costs and shrinking the boiler load. For very high BPE or extreme scaling we often deploy a hybrid MVR+MEE train to balance SEC and reliability.
Q3: What condensate quality can we expect?
For inorganic systems, distillate is usually low-conductivity and reusable; where volatiles exist we add condensate polishing (stripping, carbon, ion-exchange) to meet reuse/discharge specs.
Q4: What information do you need for a proposal?
Feed flow & composition, TDS and BPE curve, target concentration, scaling/foaming tendency, utilities (power tariff/steam/cooling), footprint limits, and desired payback. We'll return an SEC/TCO estimate and a preliminary PFD.
