The quality of finished fertilizers can be maintained during transport, handling and storage by protecting the surfaces of granules and prills with coating agents. Valuably, fertilizer coatings can also be used to control the release of nutrients in the field.
As part of the expansion of the Shah gas plant (SGP) in the United Arab Emirates, a new 12-inch pipeline was designed and commissioned in January 2020. Hassa Al Mulla, Ravi Srinivas and Alsail Al Jaberi of ADNOC Sour Gas highlight the best practices implemented in the newly commissioned liquid sulphur pipeline.
Advances in technology, equipment and reagents are enhancing phosphate fertilizer production. Optimisation of standard equipment is also vital for ensuring process efficiency.
NORAM has recently introduced a patented acid entrainment mitigation device (EMD) to deal with acid mist carryover from sulphuric acid towers.
The purpose of this article is to emphasise the lessons learned by ADNOC Sour Gas in the material upgrading of the Shah sulphur granulation plant due to severe corrosion of the aluminium components. The sulphur granulation plant was commissioned in 2015 and consists of a total of 12 granulating systems used for solidifying and granulating the liquid sulphur. The study focused on the corroded areas, namely the GX plenum chambers, the lower section of the granulator exhaust stack, the scrubber inlet and the discharge ducting.
Ammonia synthesis catalysts have seen major improvements over the last 100 years, and they are highly optimised with respect to activity, thermal stability, and poisoning resistance. Improving such catalysts even further requires a deep understanding of their structure and the impact of different parameters on performance. Clariant, Johnson Matthey and Topsoe report on their studies and developments in ammonia synthesis catalysts.
The precision mixing and granulation of mineral and organic fertilizer ingredients are essential to meet growing market demand for high-value, complex crop fertilizers. Furthermore, the ability to mix and granulate in a single machine offers fertilizer manufacturers both operational and product quality advantages over traditional granulation methods.
Efficient size preparation and ore transport are key prerequisites for successful potash and phosphate production. We highlight the range of equipment options.
Improvements to equipment and materials are driving greater operational performance and higher efficiencies at urea plants. Recent advances are reviewed.
