METHOD AND DEVICE FOR THE TREATMENT OF AN AMMONIUM CARBONATE SOLUTION

摘要

The invention relates to a method and a device for the treatment of an ammonium carbonate solution, characterized in that the ammonium carbonate solution (11) is fed into a distillation column (30) operated under pressure, wherein an ammonium carbamate melt (41) with an ammonia-to-carbon dioxide mol ratio of between 0.9:1 und 6:1 and with a water content of 2 to 20% per mass of water is condensed at the head of the distillation column (3). Thus, efficient separation is made possible.
