As Comprimo celebrates its 100th anniversary, we explore the group’s history from its earliest days in the Netherlands in the 1920s to its current status as a global leader in gas treatment and sulphur recovery technology.

Sulphur prices in China are expected to recover with downstream demand anticipated to surge in the second half of the year and good affordability to support raw materials purchasing. Chinese nitrogen, phosphate, and potash prices have surged, driven by heightened demand for the summer corn application season. In particular, average 11-44 MAP prices jumped 16% from $390/t ex-works to $463/t in Hubei province. However, sulphur prices have taken a while to follow the trend on phosphate prices. Port prices have fluctuated in the range of $126-130/t c.fr since late March, and import prices fell from a high of $112/t c.fr to $100/t c.fr, capped by high port inventory and sufficient supply. Port inventories in China remain around 2.8 million tonnes, well above the 2022 average of 1.4 million tonnes and the 2023 average of 2.07 million tonnes. These elevated stock levels limited the upside for prices in China and provided buyers with options. At the start of July, Sinopec’s Puguang, the largest sulphur producer in China, increased its sulphur sales prices at Wanzhou port up $4/t RMB980/t, while its factory price at Dazhou was up RMB20/t at RMB950/t ex-works. These prices are considerably down from RMB1,600/t in December 2022 and RMB 2,945/t from mid-June 2022 and are the lowest since July 2023, but are still up from a low of RMB605-655/t at the end of August 2020.

Aparna Saiju and Nishevitha U G of SLB-MPS explore the concept of energy optimisation using power recovery turbine (PRT) technology in amine sweetening units, focusing on its potential benefits, implementation strategies, and environmental implications.

A plant operating a spent acid decomposition furnace as part of its sulphuric acid production facility desired to increase acid production primarily by processing additional spent acid while making minimal modifications to the plant equipment and operations. The Messer solution entailed introducing oxygen in two steps, both as an enrichment to the combustion air and by direct injection into the furnace. The resulting performance improvements exceeded the project objectives for acid production and spent acid decomposition, without increasing NOx emissions. This paper provides a summary of the system start-up and tuning and presents the resulting improvements and lessons learned.

Ganank Srivastava of Bryan Research & Engineering examines ways to reduce carbon footprint in sour gas facilities.

While the events of the past few years have been difficult for Europe on many fronts, including a wholesale realignment of its energy sources with the restriction of access to Russian oil and gas, the effect on Europe’s sulphur production seems likely to be just as profound.

Desmond Long has been appointed as Chief Executive Officer of BASF Shanshan Battery Materials Co., Ltd effective April 1, 2024. In his new role, Desmond will lead the business management of the company.

Sulphur benchmarks firmed around the globe in April. Although availability remains ample, downstream production is expected to rise in the weeks ahead and further upside for prices is expected, at least in the short term. Prices increased the Middle East, Indonesia, India, Brazil, and the Mediterranean. The Middle East spot price was assessed up an average $3/t at $83-88/t f.o.b. The previous low end of the range was no longer considered achievable. The price has climbed 27% since mid-February this year. The benchmark is down 53% from early December 2022, but had climbed 47% from the end of July 2023 to its mid-October average of $110/t f.o.b. before declines set in once again. Chinese buyers returned to the international spot market in late April following weeks of inactivity, lifting c.fr prices.

Though production, particularly from sour gas in Alberta, has declined, Canada remains the world’s second largest exporter of sulphur.

Dundee Precious Metals says that it has sold the Tsumeb smelter, including all associated assets and liabilities, to China’s Sinomine Resources Group for $49 million. Sinomine Resources Group is a Chinese company founded in 1999. Its main business and operations cover four segments: EV-lithium material development and utilisation, rare and light minerals (caesium and rubidium) development and application, geo-tech services and mining property development. Dundee Precious Metals will transfer all assets debt-free and cash-free, subject to normal working capital adjustments. The transaction is subject to customary closing conditions, including approval under the Namibia Competition Act and approvals required from Chinese regulatory authorities for overseas investments, and is expected to close in Q3 2024.
