Water recycling in a melamine production process |
| abstract |
The present invention relates to a method for recycling water in a melamine production process comprising - a wet process comprising the steps of aqueous treatment of a melamine melt from a melamine synthesis plant with an aqueous alkali containing solution and crystallisation for providing solid melamine and a triazine containing alkaline mother liquor, - a wastewater treatment process comprising the steps of thermal treatment of said triazine containing alkaline mother liquor, and - a recycling process, whereby at least parts of the thermally treated alkaline mother liquor are being recycled to the wet process. |
