MVR Three Effect For 80 Tonnes Evaporation Capacity In Hungary

• Location:Hungary
• Medium：citric acid
• Evaporator Style : MVR Three Effect Plate Evaporation Capacity:20*4 T/H
• Production:62%
• Main Material:316L

1. System Overview

Type: Mechanical Vapor Recompression (MVR) Three Effect Plate Evaporator

Application: Concentrating citric acid solution to 62% solids content.

Evaporation Capacity: 80 T/H total (4 units × 20 T/H each).

Location: Hungary (customized for local climate/water quality).

Material: 316L stainless steel (corrosion-resistant for citric acid).

2. Key Components & Design Features

MVR Technology：

Energy Efficiency: Reuses secondary steam (compressed via centrifugal compressor) to reduce energy consumption by ~70% compared to traditional evaporators.

Compressor Type: Likely a single-stage centrifugal compressor (suited for 80 T/H capacity).

Three-Effect Design

Multi-Stage Evaporation:

1st Effect: Uses live steam or MVR-compressed vapor.

2nd & 3rd Effects: Reuse latent heat from previous effects, improving thermal efficiency.

Temperature Gradient: Typically 70–90°C per effect (optimized for citric acid’s thermal sensitivity).

Plate Evaporator Configuration

Advantages: Compact, high heat transfer efficiency, easy maintenance.

Plate Material: 316L SS for acid resistance.

3. Performance Parameters

Feed Concentration: ~20–30% citric acid (typical inlet).

Output Concentration: 62% (adjustable via flow rate/steam pressure).

Steam Consumption: ~0.1–0.15 kg steam/kg water evaporated (MVR advantage).

Power Consumption: ~15–25 kWh per ton of evaporated water (compressor + pumps).

4. Material & Corrosion Protection

316L Stainless Steel: Superior resistance to citric acid’s low pH (~2–3).

Gaskets: EPDM or PTFE for acid compatibility.

Surface Finish: Electropolished to minimize scaling/fouling.

5. Customization for Hungary

Climate Adaptation: Insulation for winter operation (if ambient <0°C).

Water Quality: Pretreatment (e.g., softening) to reduce scaling.

Automation: Compliant with EU standards (e.g., CE, PED).

6. Advantages vs. Traditional Evaporators

Energy Savings: MVR reduces operating costs significantly.

Compact Footprint: Plate design saves space vs. shell-and-tube.

Environmentally Friendly: Lower CO₂ emissions due to energy recovery.

7. Typical Workflow

Feed Inlet: Citric acid solution enters preheater.

Evaporation: Sequential concentration through three effects.

Vapor Reuse: Compressor recycles vapor to 1st effect.

Product Outlet: 62% concentrate discharged for further processing.
