• Plant Manager+ Problem No. 56: Oil fouling from ammonia plant
  One of the most important control parameters in urea plant operation is the synthesis pressure and a sharp increase of this pressure is very dangerous for the urea plant. One cause for an increase of the synthesis pressure is oil contamination in the urea process which causes many abnormal variations in many sections of the plant. This problem can be recognised by taking a sample from the ammonia feed and observing the colour change of the urea product. These samples and observations can prevent much confusion in determining the cause of the problem.

• Preventing ammonium nitrate misuse
  The US has been pursuing regulation on controlling the misuse of ammonium nitrate-based compounds for nearly two decades, and arguably longer, but so far progress has been very slow.

• The future of gasification
  While gasification, especially of coal, remains a common route to producing syngas, concerns over carbon emissions are slowly edging out new projects. But gasification remains a versatile process, and use of municipal waste, biomass and possibly carbon capture may yet see it flourish.

• High temperature hydrogen attack
  High temperature hydrogen attack (HTHA) is a damaging form of corrosion of steels that occurs in high temperature, hydrogen rich atmospheres. While it was characterised in the 1940s via the so-called 'Nelson curves', recent incidents have indicated that the issue may be more complex than previously thought.

• Green ammonia for a more sustainable future
  As the interest in sustainable ammonia, renewable energy and power-to-ammonia continues to grow, we report on some of the latest developments and technological advances that were presented and discussed at the 3rd European Power to Ammonia® Conference, organised by Proton Ventures BV.

• Next generation catalyst gauzes for nitric acid plants
  New designs of catalyst gauze packages and improved production technologies have been developed to meet the increasing demands from nitric acid producers. Tailor-made designs according to specific customer requirements have led to catalyst gauzes with improved overall performance and minimise the total cost of ownership for customers. New and improved catalyst gauze systems from Heraeus, Johnson Matthey and Sabin Metal Corporation are discussed.

• A unique alternative to RCF is born
  When it comes to lining fired heaters in the petrochemical industry, refractory ceramic fibre (RCF) has been the go-to material, but it has its drawbacks. Steve Chernack of Morgan Advanced Materials' Thermal Ceramics business looks at how these can be mitigated and discusses a new alternative material that meets stringent health and safety requirements.

• A flexible concept for ammonia production
  K. Wawrzinek and C. Brunazzi of Linde describe the benefits and features of the Linde Ammonia Concept for large-scale and small-scale ammonia production. Recent ammonia plants built by Linde demonstrate the flexibility of the concept, which can be adapted for different feedstocks, to produce co-products such as industrial gases and methanol or for small-scale modular plants.
