WHAT IS A FORCED CIRCULATION EVAPORATIVE CRYSTALLIZER (FCEC)?
A Forced Circulation Evaporative Crystallizer is designed for continuous concentration and crystallization of salts or solutes from industrial solutions by:
Heating the feed under controlled vacuum or atmospheric pressure.
Evaporating the solvent (usually water).
Supersaturating the solution to form crystals.
Circulating the slurry at high velocity through an external heat exchanger to prevent fouling.
Separating crystals in a centrifuge or thickener.
🔬 WORKING PRINCIPLE
Feed enters a circulation loop with a heat exchanger and crystallizer vessel.
Circulation pump ensures high flow velocity (1.5–3.0 m/s).
Steam (or MVR vapor) heats the solution → evaporation occurs.
Supersaturation forms crystals → they grow in the crystallizer body.
Slurry is withdrawn → separated via centrifuge or settler.
Mother liquor is recycled for maximum yield.
