Control architecture for evaporation plants: four-module closed loop, MVR compressor temperature-rise window, seven multi-effect control indicators, counter-intuitive diagnostics, anti-surge logic, and globe valve selection.
Representative configuration of a 22 t/h MVR forced circulation crystallizer in Southwest China (Chongqing) treating a chloride-free ammonium sulfate mother liquor at 15-22% salt,
Triple-effect counter-current evaporation with flash and cooling crystallization for barium chloride: solubility-driven process design, DTB versus FC crystallizer selection and byproduct recovery.
Feed water quality decides whether your evaporator runs clean or scales shut: MVR inlet limits (Ca/Mg <100 mg/L, silica <30 mg/L, pH 5-8), hardness
Representative configuration of a Canadian brine-to-lithium plant producing 99.9% battery-grade lithium carbonate, with UF/RO preconcentration ahead of evaporation and sodium carbonate precipitation crystallization.
Continuous zinc chloride production: multi-effect falling film evaporation, thermal-oil or molten-salt melt dehydration near 290 C, and flaking of high-purity solid ZnCl2 – engineered
How to select evaporator and crystallizer materials: titanium vs duplex vs 316L for chloride service, zoned construction cost savings, corrosion phenomena in MVR duty,
Compressor-oriented reference case: a 32 t/h ammonium sulfate wastewater MVR evaporation crystallization service in China built around a centrifugal steam recompressor — the machine
Fumaric acid evaporation and crystallization solutions: recovering saleable acid from mother liquors and saline wastewater by three-effect or MVR concentration into external-circulation crystallizers, with
