摘要： 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.

摘要： Disclosed is a catalyst suitable for the catalytic oxidative cracking of a H 2 S-containing gas stream, particularly in the event that the stream also contains methane and/or ammonia. The catalyst comprises iron and molybdenum supported by a carrier comprising aluminium. The carrier preferably is alumina. The iron and molybdenum preferably are in the form of sulphides. Also disclosed is a method for the production of hydrogen from a H 2 S-containing gas stream, comprising subjecting the gas stream to catalytic oxidative cracking so as to form H 2 and S 2 , using a catalyst in accordance with any one of the preceding claims.

摘要： Disclosed is a novel method of controlling the formation of biuret in urea production. This is accomplished by reducing or preventing the formation of biuret in a concentration section, particularly in one or more concentrators or evaporators. The method comprises controlling the residence time of a urea aqueous stream treated in such concentration section in a manner independently of the volume flow per time interval of said stream into said concentration section. The residence time can be controlled, e.g., by providing the concentration section with an adjustable volume or by adding a gas to the urea stream to be treated. A combination of such measures can also be applied.

摘要： The invention relates to the production of hydrogen by steam reforming comprising the steps of (i) providing a fossil fuel, preferably methane, and steam, (ii) conducting a steam reforming reaction between the fossil fuel and the steam under heating, wherein a reaction mixture is formed comprising hydrogen and carbon dioxide, (iii) separating hydrogen from the reaction mixture by membrane separation, wherein a permeate is formed comprising hydrogen and a retentate comprising carbon dioxide, (iv) purifying carbon dioxide from the retentate, and (v) using said carbon dioxide as a heat exchange medium to supply heat at least for the steam reforming reaction (ii). The method of the invention can also be used for the production of pressurised carbon dioxide characterised by a high purity. Further, the invention relates to a system for hydrogen production and to the use of pressurised carbon dioxide as heat exchange medium.
