HEXAMINE PLANTS
ATEC posseses the complete technological know-how and basic design / detailed
engineering expertise to build Hexamine Plants based on both Liquid Phase Ammoniation and Vapour Phase Ammoniation variants of the manufacturing process.
HEXAMINE PRODUCT / PROCESS OVERVIEW
“Hexamine”
(produced by reaction between Ammonia
and Aqueous Formaldehyde) is the short form of Hexa Methylene Tetra Amine (C6H12N4).
It has also other names like Urotropin, Methenamine, Aminoform, Crystamin,
Formin, Uritone etc. Hexamine is a solid
crystalline or granular white powder
generally having an average particle size of 40 to 60 meshes per linear
inch. It is soluble in water, spirit, chloroform etc. Hexamine is the
amino – analogue of Trioxane. In the
liquid phase process Hexamine is produced by reaction of Aqueous Formaldehyde
(AF 37) and anhydrous Ammonia in liquid forms. In a slightly different process
vapour phase Ammoniation of Formaldehyde can also be carried out. A basic flow
diagram is given below :
