Last year attention was drawn to the potential for large scale decarbonisation to leave the world short of the key resources of sulphur, and hence sulphuric acid. But is there a global sulphur shortage on the distant horizon?
The world has seen a number of hydrogen explosions in double absorption plants mostly in the intermediate absorption tower (IAT). To review this increase and to determine the causes, an International Hydrogen Safety Workgroup was formed including major acid plant contractors, major acid producers, and consultants in the sulphuric acid arena. Workgroup member Rick Davis of Davis & Associates Consulting explores some of the findings.
NORAM has recently introduced a patented acid entrainment mitigation device (EMD) to deal with acid mist carryover from sulphuric acid towers.
In its final report on the June 2019 explosion and fire at Philadelphia Energy Solutions in southwest Philadelphia, the US Chemical Safety Board has said that US refineries need to strengthen their safeguards surrounding the use of hydrofluoric acid, and has also recommended that the US Environmental Protection Agency take steps to improve its oversight of the chemical, which is used as an alkylation agent.
A report on CRU’s annual Sulphur + Sulphuric Acid conference, which returned to being face to face meeting at the end of October 2022.
The energy transition has already commenced and while sulphuric acid production is already virtually carbon free, there will likely still be impacts on the sulphuric acid industry resulting from this energy transformation. Hannes Storch, Shailesh Chandrol, Collin Bartlett and Jens Kleiber of Metso Outotec present their view on a roadmap to sustainability, preparing for energy transition in the sulphuric acid industry through permanent product development, digitalisation and new technologies.
New supply-side capacity additions in 2023 will increase export availability from the Middle East. Projects have already been ramping up in Qatar, Saudi Arabia and Kuwait.
With energy prices skyrocketing, sulphuric acid plant operators face a heightened challenge to improve plant efficiency. Martin Alvarez from Topsoe discusses how the company’s new high-activity catalyst, VK38+, can help acid plants maximise energy efficiency to secure important economic benefits while simultaneously reducing their carbon footprint.
At the organisation’s first face to face meeting since covid, in Vienna in early October, OPEC+ ministers agreed to cut global oil supplies by 2 million bbl/d in November. OPEC+ is a group of 24 oil-producing nations, made up of the 14 members of the Organisation of Petroleum Exporting Countries (OPEC), and 10 other non-OPEC members, including Russia. In a statement, the group said the decision to cut production was made “in light of the uncertainty that surrounds the global economic and oil market outlooks.”
Meena Chauhan, Head of Sulphur and Sulphuric Acid Research, Argus Media, assesses price trends and the market outlook for sulphur.
