Plant operators require effective and efficient equipment for cooling the solid materials generated during fertilizer production. The main options include fluid bed coolers, rotary coolers and bulk flow coolers.

We profile a selection of the leading players in India’s large and dynamic domestic fertilizer industry.

ICIS, the independent commodity intelligence company, provides an overview of the nitrogen market. The world supply of urea looks set to outpace market demand in 2021, as several new projects come on-stream. Global ammonia demand, in contrast, is expected to rebound strongly this year after a difficult 2020. The flurry of recent green ammonia projects announcements is another significant market development.

Globally, thyssenkrupp Industrial solution (tkIS) has engineered and built nine urea granulation plants during the last 10 years. Based on this experience, Benedict Jass, Marc Wieschalla and Ivo Mueller of tkIS describe two different cooling concepts for urea granules – fluid bed cooling and bulk flow cooling – and their contrasting advantages and disadvantages.

An industry-wide push for greater environmentally accountability is driving the need for improved fertilizer cooling methods. Not only is indirect cooling technology more environmentally-friendly, says Igor Makarenko of Solex Thermal Science, it also provides fertilizer manufacturers with a better product.

The economic conversion of phosphogypsum waste into a valuable product has been pursued for decades. Results of intensive research by thyssenkrupp Industrial Solutions (tkIS) in this area are presented by Peter Stockhoff, Dirk Koester, Stefan Helmle and Carsten Fabian. The approach developed by tkIS shows great potential as a controlled treatment process for phosphogypsum.

We highlight recent advances in ammonia and dust scrubbing systems for urea plants from Stamicarbon, thyssenkrupp Industrial Solutions and Toyo Engineering Corporation.

Phosphogypsum is finding increasing use in plaster and cement manufacture, roadbed construction and afforestation. We look at how previously unwanted solid waste generated by the phosphate industry is being turned into a valued resource.

Fertilizer coatings play an integral role in minimising the degradation of fertilizers during transport, handling and storage. Increasingly, customers also want to know if the coatings they buy are sustainable too. But what exactly is a sustainable fertilizer coating – and how can its sustainability be properly defined and measured? Lucas Moore , director of coatings technology at Arkema-ArrMaz, weighs up these thorny questions and provides some clear-cut answers.
