Industrial plants using synthesis gas at elevated temperatures risk metal dusting attack on the equipment, which are typically made of steels or Ni-based alloys. Parameters which impact the metal dusting risk are discussed and factors affecting the material selection and processing are described. One important focus is surface preparation, showing that grinding (40 grit) improves the metal dusting resistance compared to glass bead blasting and brushing. The surface treatment outweighs the impact of welds or the manufacturing route.

In 1967, Stamicarbon revolutionised the urea production process with the invention of the HP CO2 stripper by Mr Petrus JC Kaasenbrood. At a time when there was an energy crisis in many parts of the world, the HP CO 2 stripper led to three main benefits:

Indian producers have begun producing nanofertilizers at scale with the backing of the national government, as part of efforts to improve nutrient use efficiency, limit fertilizer subsidies and reduce fertilizer import dependency. But some scientists have questioned the claimed benefits and the overall efficacy of these novel crop nutrient products.

Levity Crop Science has a growing reputation as a leader in functional fertilizers, offering novel products that boost nitrogen and calcium efficiency and the crop uptake of micronutrients such as boron, molybdenum and silicon. This has culminated in the recent completion of a new research and development centre near Preston in the UK.

Dr Setareh Jamali Jaghdani and professor Jóska Gerendás of K+S Group outline how micronutrient management, by positively influencing plant physiology and development, helps maximise crop yields.

The newly-patented SWIFT process is designed to sequester fluorine at phosphoric acid plants in an environmentally responsible way. It can also offset the costs of fluorine management by generating a saleable dicalcium phosphate (DCP) end-product as an additional revenue stream. A number of capex and opex advantages provide the SWIFT process with highly favourable economics, as James Byrd of JESA Technologies explains.

We highlight recent innovations, including fertilizers recovered from industrial residues, novel controlled-release coatings, and products that incorporate biological components designed to benefit both crop nutrition and soil heath.

Sulphur plays an important role in crop nutrition. Indeed, sulphur is increasingly being recognised as the fourth major crop nutrient alongside N, P and K. However, a combination of intensive agricultural practices, increasing application of high-analysis fertilizers and tighter air quality regulations has led to increasing sulphur deficiency in soils. In this insight article, CRU’s Peter Harrisson looks at what’s driving sulphur deficiency and whether there’s a gap in the market for sulphur fertilizers.

Urease and nitrification inhibitors are cost efficient and easy to implement solutions for improving the nitrogen use efficiency (NUE) of urea ammonium nitrate (UAN). The use of inhibitors enables farmers to substantially reduce nitrogen losses and achieve their environmental targets, explains Thomas Profitt , Syensqo’s Global Enhanced Efficiency Fertilizer Manager, while improving crop yields and generating a positive return on investment.

Sulphur is a necessary nutrient for strong and healthy plant-growth and disease resistance. Fertipaq manufactures the liquid suspension fertilizer S-600 using sulphur recovered wastewater and biogas streams. This organic product is an ideal nutrient source for crops with a high sulphur requirement.
