Niro offers a broad range of technology and tailor-made applications to
meet the various property requirements.
THE GROUP
Apart from dyestuffs, polymers and
agrochemicals, which are all discussed elsewhere, organic chemicals
also entail:
- Organic acids: amino acids, salicylic acid, citric acid, maleric
acid, and ascorbic acid
- Organic salts: phthalates, stearates, salicylates, benzoates,
butyrates, gluconates, lactates, saccarates, sorbates and many others
- Nitrogen-containing compounds: hydrazines, chloramines and
ureas
The majority of organic chemicals that maintain solid form during
atmospheric conditions can be transformed to powders or granulates. The feed
material may be present as either solution, suspension of
crystals, or solids. Following the melting stage, solids as fatty acids
and waxes, can be turned into prills in a spray congealing operation.
Solutions and slurries of fine crystals can be dried to free flowing
products in a spray dryer, or to coarse granulates (1- 2 mm) in a spray
fluidizer. The remaining cakes of crystals from filters or decanters can be
dried and cooled in fluid beds.
