When digitalisation meets reality

In 2019 Topsoe launched its ClearView™ technology for WSA and SNOx sulphuric acid plants. ClearView™ is a revolutionary process health monitoring software solution to help sulphuric acid plant operators ensure plants run better, more stable and with less downtime. Now, three years later, ClearView™ has been successfully implemented at two WSA plants and several other chemical plants of Topsoe’s design, with many others in the pipeline. This article focuses on the results and learnings from the first implementation of ClearView™ at a new WSA plant at Anglo American Platinum’s Polokwane smelter in South Africa.

Market Outlook

Indonesian imports have increased in 2023 so far on a year earlier. As new nickel high pressure acid leach projects ramp up, demand for sulphur is expected to increase further. Swing buyers have been importing significant volumes of sulphuric acid, affecting short term sulphur demand in the second quarter. It remains to be seen if this will continue, we expect sulphur demand to ramp up further in the second half of the year, bringing import expectations for the year to around 2 million t.

The age and friability for different forms of elemental sulphur

Aged sulphur products can be friable and fragile, which can lead to sulphur dust during handling. Because sulphur dust can lead to dust explosions and excessive wet sulphur contact corrosion, shipping and handling specifications for the safest products are used by producers, shippers and consumers to limit dangerous incidents. Metastable polymeric sulphur in the solid product limits friability and is rarely cited as a measured quantity within sulphur specifications, but often discussed when explaining best handling and forming practices. In this article, ASRL discusses why sulphur tends to be friable and explores several measurements cited in many specification documents, with the purpose of focusing on several modern solid forms. In addition, the measurement of total and extraneous water is explored.

Metso Outotec’s annual general meeting (AGM) in early May approved the board of directors’ proposal to change the company name to Metso Corporation. “After the successful integration of Metso and Outotec, we will focus on growing a strong unified Metso company and brand,” says President and CEO of Metso, Pekka Vauramo. “We have combined two valuable companies into one strong Metso. Our focus is clear: we continue enabling sustainable modern life and transforming the industry with a clear strategy and strong culture, supported by a name that is short yet established and well recognized among all our stakeholders.
