Abstract: Disclosed is a novel method of controlling the formation of biuret in urea production, and particularly reducing, preventing or reversing such formation. This is accomplished by adding liquid ammonia to a urea aqueous stream. This addition is done at one or more positions downstream of a recovery section in a urea plant. The addition of liquid ammonia serves to shift the equilibrium of biuret formation from urea, to the side of the formation of urea from biuret and ammonia. The invention can be accomplished also in pre-existing urea plant, by the simple measure of providing an appropriate inlet for liquid ammonia, in fluid communication with a source of such liquid ammonia.

Abstract: 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.

Abstract: Disclosed is a process for the preparation of a urea product suitable for being diluted with water so as to form an aqueous urea comprising solution for use in a unit for the reduction of NOx in combustion engine exhaust gases, also known as Diesel Exhaust Fluid (DEF) or to be used in De NOx systems of exhaust vapor from industrial furnaces. The process comprises obtaining an aqueous urea solution from or after a recovery section in a urea production process. This solution, which has a low content of impurities, is subjected to flash crystallization at a low pressure, so as to obtain a solid crystallized urea containing product, which is a free-flowing powder containing less than 0.2 wt.% water. This product is packaged under conditions such that the water content in the packaged product is maintained below 0.2 wt.%. The invention can also be used in a method of increasing the capacity of an existing urea plant.

Abstract: Disclosed is a method for the removal of soluble particulate matter from a gas stream, such as urea dust from the off-gas of a finishing section of a urea production plant. The method comprises subjecting the off-gas to at least two quenching stages an aqueous quenching liquid. The quenching liquid used in a first, upstream quench stage, is allowed to have a higher concentration of dissolved particulate matter than the quenching liquid in the second, downstream quench stage. The quenched gas is led through a particle capture zone, typically comprising one or more of a wet scrubber, a Venturi scrubber, and a wet electrostatic precipitator.
