Optimisation of the nitric acid process depends on good process visualisation tailored to the specific process parameters of the plant, improvements in combustion efficiency, reduction of N2 O emissions and the optimal use of platinum group metals.
Most nitric acid is used for production of fertilizer nitrates and ammonium nitrate explosives, but it is also used in polyamides, polyurethanes and aniline dyes as well as a number of industrial processes including ore treatment. High ammonia prices have pushed nitric acid prices to record levels this year, but growth predictions remain robust.
Casale reviews urea plant revamping process schemes and successful case studies for energy savings and TOYO discusses its latest revamping technologies including application of the new generation low-pressure, energy-saving ACES21-LP™ process.
The war in Ukraine has severely affected the supply of ammonium nitrate and CAN from Russia and Ukraine, with particular potential impact on Europe and Latin America. Can urea make up the difference?
The fertilizer price and supply chain shocks caused by the war in Ukraine have supercharged the debate about the shift to more sustainable and efficient crop nutrition – with farmers and governments urgently looking for different approaches to maximise crop productivity.
A record rise in gas prices at the end of August triggered a spate of ammonia production curtailments across Europe. These included major shutdown announcements from CF Fertilisers UK, Grupa Azoty, Yara International and others.
Nowadays, fertilizers can be produced in many different colours. But what is the significance of colour and its role in improving fertilizer product quality? In this article, Jervis Bao (Jiabin Bao), R&D director, Arkema-ArrMaz China, explores some common questions about colourants and their use in the fertilizer industry.
Applying dissolved fertilizers via micro-irrigation systems or leaf sprayers offers commercial fruit and vegetable growers clear-cut gains – in terms of input costs, nutrient use efficiency, labour, time and energy.
The Broadfield process has remained a mainstay of the global phosphate industry since its introduction in the 1930s. Ian Hancock, vice president sales & operations, Bradley Pulverizer, explains it continuing success in superphosphate production worldwide
The drive for ever higher crop yields is shifting the focus onto secondary nutrients such as calcium and magnesium. In this article, we look at the role of magnesium and calcium in crop nutrition and the main fertilizer product options.
