Products Produced from the Melamine Reactor System
Melamine (60,000 tons/year)
By-Products: Ammonia and Carbon Dioxide (2 tons/ton of Melamine)
Two Methods of Melamine Production
Conventional Melamine Process
New Integrated Urea-Melamine Process
This Process Produces High Quality Melamine and Has Lower Investment and Energy Costs Than Conventional Production Methods
The main improvements of the newly developed integrated urea-melamine process compared with the conventional
gas- phase melamine process are:
heat recovery from the by-products ammonia and carbon dioxide
export of water-free by-product gases to the urea plant without a concentration unit
synthesis of melamine melt instead of melamine vapor
integrated purification of the melamine melt without a re-crystallization unit
water-free quench process producing directly dry powder
low cost ammonia recovery due to separation of by-product gas before the quench
Melamine Application Areas
The main application for melamine is a raw material for the production of melamine formaldehyde resins, which are used as an adhesive for wood-chips; giving laminated panels and floors their unique surface properties and attractive finishes.
