Abstract
Disclosed is a method for treating or using offgases obtained in a melamine plant comprising at least one melamine synthesis reactor and at least one washing unit in an integrated process for urea and melamine production, wherein the offgases leaving the melamine synthesis reactor are fed into the washing section and the washed offgases leaving the washing section are transferred from the washing section via at least one pipeline connecting the washing section and the at least one urea synthesis plant to the at least one urea synthesis plant. The washed offgases leaving the washing section are mixed with at least one carbamate solution immediately downstream of the washing section by feeding the carbamate solution into the pipeline connecting the washing section to the urea plant.
