Abstract: PROBLEM TO BE SOLVED: To provide a process for increasing the capacity of a urea plant including a compression section, a high-pressure synthesis section, a urea recovery section in which a urea melt is formed, and optionally a granulation section.
SOLUTION: By the additional installation of a melamine plant to the urea plant, a urea melt from the urea recovery section of the urea plant is fed wholly or partly to the melamine plant, and the residual gases (containing carbon dioxide and ammonia) from the melamine plant are returned wholly or partly to the high-pressure synthesis section and/or the urea recovery section of the urea plant, whereby the production capacity of urea is increased.
