Asos Process GmbH
About
ASOS Process GmbH, based in Düsseldorf, Germany, designs and manufactures crystallization, evaporation, drying, and granulation systems for the chemical, fertilizer, mining, and environmental sectors. Their crystallization line includes DTB (draft tube baffle) crystallizers for producing large uniform crystals, Oslo-type crystallizers for classified-suspension growth with minimal fines, and forced-circulation MSMPR crystallizers for continuous high-throughput production. The evaporation portfolio spans falling film evaporators for heat-sensitive solutions, forced circulation evaporators for viscous or scaling feeds, multi-effect systems for energy-efficient concentration, and both thermal vapor recompression (TVR) and mechanical vapor recompression (MVR) units that recycle process vapor to reduce energy consumption. For drying, ASOS offers fluidized bed dryers, belt dryers, spray dryers, rotary dryer-calcinators for combined drying and thermal treatment, paddle dryers for sticky high-moisture materials, flash dryers for rapid pneumatic drying, and plate coolers. Granulation equipment includes fluidized bed granulators, rotary granulators, and mixer granulators for fertilizer and mineral agglomeration. The company provides turnkey delivery from pilot testing through commissioning and after-sales support, with reference projects including lithium carbonate production plants, monoammonium phosphate (MAP) fertilizer facilities, and sewage sludge fluidized-bed drying systems. Clients include Ege Kimya, Cargill, Çimsa, and Şişecam.
Key Products
Draft tube baffle crystallizer for producing large, uniform crystals from solution in chemical and fertilizer production with controlled crystal size distribution.
Oslo-type crystallizer producing crystals with controlled growth in a classified fluidized bed for high-purity crystal production with minimal fines.
Mixed-suspension mixed-product removal crystallizer with forced circulation for continuous crystal production at high throughput rates.
Thin-film evaporation system where liquid flows downward as a film on heated tube surfaces, achieving high heat transfer efficiency for concentration of heat-sensitive solutions.
Evaporation system using forced recirculation of process liquid through a heat exchanger, suited for handling viscous, scaling, or fouling-prone solutions.
Energy-efficient evaporation system using multiple sequential stages where vapor from one effect provides heating for the next, significantly reducing steam consumption.
Evaporation system that reuses process vapor through steam jet compression to achieve moderate energy savings for concentration applications.
Evaporation system using a mechanical compressor to recycle process vapor, achieving the highest energy efficiency for industrial concentration operations.
Industrial dryer using hot air to fluidize and rapidly dry granular materials including sewage sludge, with excellent heat transfer and uniform moisture removal.
Continuous conveyor belt dryer that passes material through a heated drying chamber for consistent, gentle drying of sludge, sludge granules, and other bulk materials.
Atomization dryer that transforms liquid feeds into dry powder by spraying into a hot air stream for instant moisture removal, used in chemical and mineral processing.
Rotating drum dryer that performs both drying and calcination of bulk materials through direct or indirect heat transfer for thermal treatment applications.
Indirect dryer using rotating paddle elements for heat transfer, suited for pasty, sticky, or high-moisture materials that require gentle handling.
Rapid pneumatic drying system that suspends material in a high-velocity hot air stream for instantaneous moisture removal with very short residence time.
Heat exchange device using plate surfaces for cooling process streams after drying or other thermal operations to prepare materials for downstream handling.
Granulation system using fluidized bed technology to agglomerate fine particles or powder into larger, uniform granules with controlled size.
Drum-based granulation system that forms and rounds granules through rotation and binder application for fertilizer and mineral products.
High-shear mixer that combines powder ingredients with binder liquid to form granules in a single vessel for chemical and fertilizer production.
