Engineer-to-order MVR (Mechanical Vapor Recompression) evaporator integrated with an FC (Forced-Circulation) crystallizer for potassium chloride (KCl) concentration and crystal production. The train is sized for a nominal 3 t/h water removal, delivering stable supersaturation control, narrow crystal size distribution, and low OPEX for potash brines and carnallite conversion lines.
Potash brine is purified and concentrated under vacuum in the MVR body. The forced-circulation crystallizer runs at controlled slurry density and ΔT/LMTD; recompressed vapor provides the primary duty, achieving low specific energy while promoting predictable KCl crystallization and clarity.
Wetted parts in SS316L/duplex (Ti/Hastelloy on request) for chloride-rich brines. Drainable layouts, large clean-outs, and validated CIP extend campaign length and simplify turnarounds.
| Parameter | Typical Target / Range* |
|---|---|
| Evaporation rate | 3 t/h (water removal), adjustable via compressor VFD |
| Operating mode | Vacuum, continuous |
| KCl purity (dry) | ≥ 98–99% (feed-dependent, with proper purification) |
| Crystal size bands | Fine 0.3–0.6 mm; Standard 0.6–1.0 mm; Coarse 1.0–2.0 mm |
| Electric use (MVR) | ~15–40 kWh per ton H₂O evaporated (duty/CR dependent) |
| Fresh steam demand | Very low after start-up (backup/ancillary only) |
| Materials | SS316L / duplex; Ti/Hastelloy on request |
*Performance depends on brine composition (K⁺/Mg²⁺/Na⁺), scaling tendency, compression ratio, and crystallizer design.
Yes—flowsheets can include Mg control and hot leach steps; the FC crystallizer is tuned for KCl selectivity and PSD.
Optimized ΔT/velocity, antiscalant dosing, and scheduled CIP maintain heat-transfer coefficients and crystal purity.
Yes—the MVR+FC module ties into upstream purification and downstream centrifuge/dryer/screening with minimal retrofit.
