Information about Organic Chemicals

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. For further information please refer to "Spray Cooled Products".

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.
