Sulphur production continues to expand in the Middle East and China both from new refineries and major sour gas projects.

The sulphuric acid process is virtually carbon free and, as such, it is important to consider the energy requirements of the associated industrial complex before deciding upon what form the energy should be exported from the acid plant. In this article, Stefan Braeuner, Stefan Mohsler and Anne Mohsler of Metso Outotec use case studies to exemplify the need to fully analyse the local conditions at site before a decision is taken on a specific flowsheet.
Suncor has selected Rich Kruger to be the company’s next president and CEO, effective from April 3rd, according to the company. Kruger will also join the Suncor board of directors. The announcement follows a search process conducted by a special committee of the board. Rich Kruger previously worked for ExxonMobil for 39 years, and was the chairman and CEO of Imperial Oil Ltd from 2013 through 2019 before retiring from the company, where he focused on safety, reliability and operational excellence. Kris Smith, who has been interim CEO since July 2022, will work with Kruger to ensure a smooth transition before assuming the role of Chief Financial Officer and Executive Vice President of Corporate Development, at the conclusion of Suncor’s annual general meeting on May 9, 2023. Alister Cowan, the current CFO, plans to retire but has offered to remain with the company through the end of the year to support the transition to Mr. Smith and to provide advisory services. Smith replaced previous CEO Mark Little, who resigned in July 2022 following investor pressure after a series of safety incidents and fatalities.
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.
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.”
Marco van Son and Frank Bela of Comprimo share lessons learned from SRU war stories, including: inadvertent NH3 destruction in an oxidising atmosphere, rich amine emulsion, SWS fixed valve trays, H2 spiking of SRU feed, rich amine flash drum early warning, V-ball fuel gas safety shutoff valves, TGTU methyl mercaptan, and commissioning and Murphy’s Law.
The past couple of years have been quite the wild ride, with major global events dominating markets outside of the usual concerns of broad market supply and demand. It seems like a long time ago now, but this time last year, the price of a barrel of Brent crude was about $75. Go back two years, in the wake of the onset of covid restrictions, and that barrel would have cost you $40 (and just $25 a couple of months before that). In the wake of Russia’s attack on Ukraine, you could easily have paid $130, and it has been hovering around $110/bbl for the past few months. The last time oil spent any time at that level was in 2014, just before the Chinese economy ran out of steam and prices slumped by 70%.
Copper leaching and smelting projects in Zambia and Zimbabwe continue to dominate acid production and consumption, with output expected to increase from the Kamoa-Kakula project.
Researchers from Australia’s Monash University say that they have created a new generation of lithium-sulphur batteries which could provide a cheaper, cleaner and faster-charging energy storage solution that outlasts lithium-ion alternatives and is rechargeable hundreds of times without failing. The team has creating a new interlayer which allows for exceptionally fast lithium transfer, as well as an improvement in the performance and lifetime of the batteries.
US refiners have upgraded to take advantage of generally cheaper, sourer crude feeds. However, a ban on oil imports from Russia may make that harder to come by.
