Disclosed is a method for the integrated production of two different urea products. One is an aqueous urea solution suitable for use in NOx abatement (generally indicated as Diesel Exhaust Fluid DEF). The other is a solution used as a fertilizer, viz. Urea Ammonium Nitrate (UAN). The production of DEF and UAN are integrated as follows: ammonia recovered from the production of urea is used as a feed to the production of ammonium nitrate. At least part of an aqueous urea stream from urea production, is mixed with ammonium nitrate so as to obtain UAN.

The present invention provides solvent-limited processes for the preparation of an existing crystalline solid form of an active pharmaceutical ingredient comprising mixing, in the presence of solvent vapour, of a solid active pharmaceutical ingredient and a pharmaceutically acceptable entity that is either a high-boiling liquid or a solid. Also provided is the use of a standard rotary apparatus, such as a rotary cone dryer, for application of the processes herein.
