In the field of vacuum salt processing GEA Messo PT has designed and supplied various refining concepts as listed below:
- Vacuum salt plants using raw brine by ESCHER WYSS technology for Gypsum slurry operation (multiple effect, thermal- and mechanical vapour recompression).
- Vacuum salt plants using purified brine for high grade salt 99.99% NaCl (multiple effect, thermal- and mechanical vapour recompression).
- Combined sodium chloride / sodium sulphate plants developed by GEA Messo PT with recovery of sodium sulphate by the technology utilizing high / low temperature circuit for high purity requirements
- Recrystallization plants for rock salt and solar or other raw salt suitable for human consumption and industrial use
- Complete vacuum salt plants with brine purification, storage and bagging facilities, logistical equipment
The most common crystallizer type used for salt is the Forced Circulation Crystallizer (FC- type). The average particle size can be adjusted between 0.3 to 0.5 mm. For granular qualities Oslo crystallizers are in use with particle sizes up to 2.5 mm. Plant capacities vary from 2 to 15 tons/hr based on solar salt and up to 200 tons/hr based on rock salt.
GEA Messo PT has extensive know how and experience in designing the components in special material of construction like monel, titanium, special alloys and stainless steel.
