Phosphate and potash mining update
We look at state-of-the-art technology used in phosphate and potash mining, including equipment and systems for excavation, tailings thickening, transport, tunnelling and processing.

The Ma’aden Wa’ad Al Shamal Phosphate Company (MWSPC) has signed a service agreement for a period of three years with DuPont Clean Technologies for its sulphuric acid plant at Sirhan. The service programme will include activity testing of catalyst samples, evaluation of catalyst performance, plant optimisation, troubleshooting and management of catalyst replacement. DuPont says that it will also track plant performance and assess its overall health using pre-agreed metrics and its proprietary PeGASyS™ gas chromatography system, which can be used to detect possible leaks in gas-gas heat exchangers, identify SO2 gas bypassing and measure overall plant conversion in order to optimise plant operation, reduce SO 2 emissions, increase production and improve converter performance.
M. van Son and S. Sreejit of Comprimo present a case study involving the design and potential integration of the sour water and acid gas treatment units for a renewable diesel facility with an existing refinery sulphur complex. The case study evaluates the potential for operating cost reduction by integrating an enrichment loop in the acid gas treatment plant as well as for using the existing infrastructure of the refinery to limit emissions.
Using case studies of a refinery amine unit and a sour water stripper (SWS), U. M. Sridhar of Three Ten Initiative Technologies LLP, N. A. Hatcher and R. H. Weiland of Optimized Gas Treating Inc. demonstrate the capabilities of a mechanistic, chemistry-based, truly predictive model for calculating corrosion rates for various amines and for sour water. At a time when asset integrity is much sought after, the utility of this fully predictive model is to prevent failures before they occur, rationally select materials of construction, enhance plant safety, and mitigate risk.
Sulphuric acid plant operators juggle multiple issues trying to keep their plants running efficiently and reliably. With the revolutionary ClearView™ process health monitoring solution, as well the DynSOx™ software for simulating dynamic operation, Haldor Topsoe strives to bring digital services with real and tangible operational benefits to the sulphuric acid industry. P. Szafran and M. Granroth discuss how together these digital services can help acid plant operators meet their daily targets.
thyssenkrupp Industrial Solutions (tkIS) offers and builds Power-to-X plants and can provide all processes of the value chain, from water electrolysis and CO2 recovery to green ammonia, green methanol and green SNG. Renewable methanol production, which combines the application of carbon capture and utilisation with chemical energy storage, is a particularly promising sustainable solution.
