Extra information

This machine (Elemetal Zinc Sulphate MVR System) is an evaporation/crystallization unit that concentrates zinc sulphate solution past saturation so zinc precipitates as ZnSO₄·1H₂O crystals. The crystals are then separated from the mother liquor in a decanter centrifuge, producing a solids cake for downstream drying and clean condensate that can be reused.

The complete plant/module consists of (main machines/equipment):Feed section: feed pump and feed preheater:
Feed to the module: 1065 kg/h, 50°C, 29% TDS.
Feed is preheated in PH01 (TL6 PHE, 28 plates, C276 plates, EPDMP gaskets) to about 76°C using hot condensate (heat recovery).

Evaporation/crystallization: AlfaFlash plate evaporator/heat exchanger, separator vessel, recirculation pump, condensate pump, de-superheating/condensate spray arrangement:
Main evaporator/heat exchanger: E10-W10 AlfaFlash PHE (M15, 78 plates: 74× C2000 + 4× Titanium, EPDMP gaskets).
Flashing and separation: slurry flashes after an orifice and enters cyclone separator E10-SE10 (vapour out top, liquid/slurry out bottom).
Recirculation pump E10-P10: 100 m³/h, 2.1 bar, 22 kW.
Condensate pump E10-P11: 1 m³/h, 3.6 bar, 2.2 kW.
De-superheating spray: small condensate stream sprayed into vapour before MVR (flow indicator range 60–160 L/h).

MVR/steam section: MVR blower/compressor (steam used mainly for start-up/makeup)

Condenser section: condenser with condensate pump:
Condenser pump CO50-P50: 0.1 m³/h, 2.0 bar, 1.1 kW

Vacuum section: liquid-ring vacuum pump with seal-water cooler and vacuum separator vessel :
Vacuum pump VA60-VP60: liquid-ring, 30 m³/h, 1.1 kW.

Solids recovery: decanter centrifuge, centrate tank and centrate pump:
Centrate pump PD70-P70: 5.0 m³/h, 1.2 bar, 1.5 kW

Condensate handling/cooling: condensate cooler and condensate/hot-water tank:
Condensate cooler PD70-W70: PHE M6, 12 plates, 316 plates, EPDMC gaskets.

Utility/CIP system (outside battery limits but part of the overall plant): seal-water tank (310-TK01) and pump, rinse/wash-water tank (310-TK03) and pump, CIP tank (310-TK04) and pump:
CIP connections provided: CIP liquid and hot water can be fed into the module for cleaning.
CIP modes listed: hot water, caustic, caustic + acid.

Control system: control panel with HMI/SCADA
