Filtration and washing
of an amino acid with BoHiBar drum filters
For the filtration of an amino acid, a Chinese producer has been operating three BoHiBar Drum Filters M12 (each 12 m² filter area) for about two years. They are operated for the filtration of the crude product. Due to the reliable, economical operation and the good process results of these three BoHiBar drum filters, the customer decided to use BoHiBar drum filters also for the filtration of the pure product.
After filtration of the crude product, the amino acid is recrystallized to produce the pure product. The separation and washing of the pure product was previously performed on nine centrifuges. The customer has now ordered two BoHiBar Drum Filters M12 for this task. They will replace the nine centrifuges in the future. The BoHiBar drum filters enable the customer to carry out the separation and washing of the pure crystals in a gentle way. In addition, the Chinese producer was impressed by the excellent adaptation of the filter operation to different challenges due to changing product characteristics and the significant savings in investment and operating costs.
In the future, only BOKELA filters will be used in the production of this amino acid for all challenging separation stages.
