Technologies and process installations for processes of evaporation and crystallization from solutions

Manufacturer: HPD S.A.

Application:

• evaporators, concentration systems and crystallizers (water vapor, operation under vacuum)
• heat exchangers, condensers, distillation columns, degassers
• auxiliary equipment (filters, centrifuge, driers)
• stripping columns (control and elimination of odors)
• non-waste installations for treatment of liquid sewage in power industry, refineries
• recovery of substances contained in circulating waste streams (profitability improvement, limiting negative influence on environment)
• recovery of salt contained in chemical wastes (also organic)
• systems for volume reduction of poisonous and radioactive liquid wastes
• neutralization of saline liquid wastes for salt recovery
• concentration systems for spent beer, whey (in ethanol, biofuel production)
• crystallization of ammonium sulfate, potassium and sodium nitrate, phosphoric acid (fertilizers)
• crystallization of lithium salt, titanium, magnesium and zinc; vanadium, molybdenum, tungsten  crystallization products, concentration of cleared aluminum oxide liquid, recovery of oxalates
• preliminary processing of solutions from extracted natural ores,
• crystallization of sodium carbonate and bicarbonate, minimizing wastes and lye recovery
• herbicides, aminoacetic acid, synthetic sweeteners, bisphenol-A, thiocyanate
• industry for processing chlorides, lye and carbonates: purification of NaCl solution (periodical, constant), vaporization of NaCl solution, crystallization of NaCl, concentration of NaOH solution to 50% concentration,
• purification of sulfates through crystallization (Glauber's salt Na2SO4 x10H2O, anhydrous Na2SO4), sodium chlorate NaClO3
