Description
We are offering a quality assured range of Melamines. The chemicals offered by us are prepared using urea, which simplifies the recovery of melamine, carbamate and ammonia from a fluidized bed reactor effluent stream with the process at a pressure between 1.4 and 2 MPa. Without an intervening concentration step, a carbamate solution can be produced sufficiently high concentration in such a manner for use in a urea plant. In addition, to permit easy separation of noncondensables such as oxygen,. which used in the process as a passivator for carbamate corrosion inhibition, ammonia recycled as a fluidized gas can be condensed against cooling water. Free of melamine solids, this product is produced as an aqueous solution. Further, heat is recovered from the carbamate condensation, which is used for evaporating ammonia that is recycled to the reactor for fluidization.
