Meena Chauhan, Head of Sulphur and Sulphuric Acid Research, Argus Media, assesses price trends and the market outlook for sulphur.

After two years of virtual events, the CRU Sulphur + Sulphuric Acid 2022 Conference & Exhibition will return to an in-person event at the World Forum, The Hague, 24-26 October 2022. CRU will be welcoming the global sulphur and sulphuric acid community to this premier annual event for networking and essential updates on the markets and technical developments that are influencing the industry.

By recovering waste heat as process steam or electrical energy, technologies are available that can help sulphuric acid plants meet their energy goals. Colin Shore of Elessent Clean Technologies discusses how MECS® HRS™ technology can offer a sustainable solution to enhance sulphuric acid plant performance, while lowering its carbon emissions.

Wet process phosphoric acid plants require reliable cooling water facilities. Jan Tytgat, engineering manager, De Smet Agro, shares his insights on the design and operation of cooling water networks, pumps and towers.

The phosphate fertilizer industry is turning to production methods that are able to consume low-grade phosphate rock and/ or generate pure gypsum as a by-product. Gypsum-free processes, and technologies that capture phosphorus from waste streams, are also on the rise.

At the end of June a three day strike among workers at Chilean state mining company Codelco paralysed copper output at the world’s largest copper producer. The strike was in protest at the threatened closure of the Ventanas smelter, which was the site of an alleged leak of sulphur dioxide on June 6th. Chile’s environmental regulator subsequently provisional measures for both Codelco and power company AES Chile after numerous people in the nearby towns of Quintero and Puchuncavi in central Chile, including hundreds of high school students and staff, showed signs of sulphur dioxide poisoning. The measures include the installation of a new temperature sensor to measure potential thermal inversions. Both companies have denied responsibility for the leak; Codelco says that its air quality stations recorded normal levels of SO2 during the time of the incident.

The ongoing recovery from Covid-19 has led to an uptick of sulphur from refineries in regions including the US compared with a year ago. As travel around the global improves, increasing fuel demand points to higher operating rates and improved sulphur recovery.

The Sulphur Institute’s (TSI’s) annual Sulphur World Symposium was held in Tampa, Florida this year, from May 9th-11th.

E. Almeida and B. Ferraro of Clark Solutions discuss how regular monitoring by simple testing of the towers in sulphuric acid plants can improve the reliability and lifespan of the plant.
