Abstract
Disclosed is a urea plant comprising an additional reactor. With reference to the regular components of a urea plant, including a recovery section and a high pressure carbamate condenser, the additional reactor is positioned between the recovery section and the high pressure carbamate condenser. The invention also relates to a process for the synthesis of urea, comprising an additional reaction step converting, at an earlier stage than conventional, recovered carbamate into urea.
