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.”

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.

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.

The trend for multicomponent analysis of emissions from sulphur recovery units is becoming more widespread. David Inward of Sick reports on a recent field trial to test the suitability of a hot extractive infra-red analyser for this application. In addition to reliably measuring and reporting emissions to air, the analyser is also capable of contributing to reducing overall tail gas emissions by supporting enhanced optimisation of the thermal oxidiser.

The fourth SulGas Conference organised by Three Ten Initiative Technologies took place 1-4 February as a virtual event. Selected highlights from some of the presentations from SulGas 2022 are given below.

As the world looks to a lower carbon future, refineries are having to examine their operating models, and look to, for example, renewable hydrogen production for desulphurisation technologies.
