Abstract: The present invention presents a stripping process for urea production with a total recycle. An important characteristic of the described urea process is a substantially complete CO 2 conversion, which eliminates the need for carbamate recycle from the recovery section to the synthesis section. This increases the overall conversion and reduces operation costs.
