In a process for the production of urea, substantially pure ammonia and carbon dioxide are reacted in a reaction space wherefrom there exits a reaction mixture which is sent to a urea recovery section. From the recovery section, a carbamate diluted solution is obtained which is submitted to stripping with recycling of vapours to the reaction space, on prior condensation of the same. This process allows to achieve a high conversion yield at low energy consumption and implementation costs.
