We profile leading suppliers of tailor-made pumps and pipes to the phosphates and sulphur industries.

Erosion and corrosion are two of the biggest challenges faced by equipment used in phosphate fertilizer production. This harsh operating environment requires exceptionally well-designed pumps made from sophisticated and robust construction materials. Hani Tello of ITT Rheinhütte and Harvinder Bhabra of ITT Goulds Pumps outline the range of options.

Newly developed flotation reagents are improving the selectivity and grade/recovery of phosphate and potash concentrates.

Conventional fertilizers can be transformed into enhanced efficiency fertilizers (EEFs) using coating agents and inhibitors. Greater use of EEFs, by preventing nutrient losses and avoiding excess nutrient supply, can help global agriculture become more sustainable, as Urvi Mathur of Neelam Aqua explains.

As sulphur recovery units operate at progressively higher temperatures, creep stress in the furnace refractory lining can lead to deformation or even failure of the bricks and require the shutdown of the SRU. UK-based DSF Refractories have developed a product which minimises creep stress damage at high temperatures, for a longer-lived furnace lining.

New low-cost metal oxide solid scavengers for hydrogen sulphide (H2 S) removal from wet and dry natural gas have been developed and deployed at commercial scale. The desulphurisation process uses a proprietary sorbent chemistry to achieve a high sulphur capacity and removal efficiency. G. Alptekin, F. Kugler and M. Schaefer of SulfaTrap LLC describe the new technology and its performance.

T. Hentrich and B. Nowak of VDM Metals provide an overview of the development of VDM® Alloy 699 XA, a new generation, metal dusting resistant alloy, available in a wide range of product forms, for demanding applications in the chemical process industry.

With demand for conventional fuels projected to peak and fall over the next decade, some refiners are looking to petrochemical production as a way of diversifying their product slate.

Filters can be a common bottleneck in overall plant operations. Jerold Johnson and Brad Bentley of WesTech outline how upstream modernisation or upgrades to the thickener can have significant benefits for the efficiency of filter operations downstream. Results are applicable to the dewatering of phosphate tailings and other fine particle tailings.

Philippe Malsan of Technip Energies explains how high recovery Diplo phosphoric acid technology can generate phosphogypsum suitable for industrial reuse. Industrial cases studies for Senegal and Austria show how phosphogypsum from this process has been successfully recycled on a large scale for cement, plaster and other end uses.
