Abstract: A process for the production of urea from ammonia and carbon dioxide via synthesis where the urea formation takes place in a synthesis zone (or zones) in which an excess of free ammonia is kept to favor high conversions, said synthesis zone (or zones) being followed by an ammonia separation and direct recycle to the reaction step, where the urea solution from said reaction zone (or zones) is intimately contacted for a short duration time with a minor portion of the fresh CO.sub.2. The separation step is followed by a CO.sub.2 stripping step where the residual carbamate is removed using a countercurrent fresh CO.sub.2 stream.

Abstract: One approach to improving storage stability, particularly that attribute characterized by reduction in the tendency for caking during storage of freshly prepared urea particles such as granules, is to treat the surface areas of the freshly prepared particles/granules with appropriate amounts and kinds of conditioning agents. This approach does not address the problem of increasing the hardness of the particles to impart improved high-strength characteristics thereto. A second approach to this problem of improving storage stability of urea granules is to admix and/or react certain anticaking and hardness improving additives into or with the urea melt prior to the solidification of urea particulates therefrom. The instant invention is directed to this second approach of imparting to the ultimately prepared urea particles both improved anticaking and hardness (as opposed to being easily crushed, i.e., friable) characteristics by means of addition to the urea melt of certain additives.
