Thermal Kinetics Engineering has recently completed design and supply of equipment for the production of anhydrous sodium sulfate. Our involvement included preparation of the processing plant’s material and energy balance, design layout of all major equipment from receipt of raw ore, ore dissolving, purification, clarification, crystallization, centrifugation, and drying operations.
We designed and supplied the evaporative crystallization equipment including heat exchangers, crystal bodies, axial flow pumps, controls, and supporting equipment. The system was configured as a quadruple effect operation for minimum steam usage. Advanced controls and processing allows crystal size distribution to be managed by operations. Each effect operates at a different temperature influencing crystal growth and nucleation kinetics. Control of slurry density and crystallizer body levels for each effect balances the temperature impact for consistent crystal size control in each effect.
The plant is nearing completion of construction for Somin Compañia Minera in Hermosillo, Sonora, Mexico.
