A selection of innovative products and technologies that have recently been brought to market.

Some 410 delegates from 208 companies and 45 countries participated virtually in the IFA Global Sustainability Conference, 28-31 March 2022. We report on the main highlights of this four-day event.

The economic conversion of phosphogypsum waste into a valuable product has been pursued for decades. Although phosphogypsum is still generally disposed of as waste, industry attitudes are changing and greater use of phosphogypsum will be expected in a circular economy.

The CRU Nitrogen + Syngas Conference returns to Berlin for a live event from 28-30 March 2022. The conference will be run as a hybrid event giving participants the option to attend live in-person or online via the virtual platform.

More than 230 delegates from 45 countries participated in CRU’s Sustainable Fertilizer Production Technology Forum, 20-23 September 2021. To highlight this successful virtual event, we report on keynote and selected technical presentations.

Like the vital nitrogen fertilizer they handle, seasonal cheer will be in short supply for Europe’s ammonia producers and buyers this festive season, after many difficult months in which upward price trajectories showed no sign of slowing.

Johnson Matthey and MyRechemical have formed an alliance to commercially develop waste to methanol technology. In this article, two different approaches to waste disposal and chemical production are analysed: a post combustion scenario with waste incineration and hydrogenation of the CO2 recovered from flue gas to produce methanol, and a precombustion approach with waste gasification followed by conversion of synthesis gas into methanol.

MegaZonE™ is a newly introduced layered loading technology for boiling water-cooled reactors used for methanol synthesis. This new concept is one of the latest results of the long-standing collaboration between Air Liquide Engineering & Construction and Clariant Catalysts to improve the methanol process flowsheet and optimise catalyst performance in the complete reactor system.

Production has begun at Ivanhoe Mines’ Kakula copper mine in the DRC. The company says that total production for this year is expected to be 80-95,000 t/a of copper in concentrate, with a phase two expansion to 400,000 t/a due to be completed by Q2 2022. Ivanhoe is working with China’s Zijin Mining on the development plan for phases 2 and 3 of the mine, as well as a feasibility study for the Kipushi zinc mine further to the east. Both projects lie close to the DRC’s southern border, with Angola and Zambia respectively. Phase 3 of Kamoa will lift capacity to an anticipated 600-800,000 t/a of copper in concentrate, making it the second largest copper mine in the world after Escondida in Chile. Canadian-based Ivanhoe expects to be digging 3.8 million t/a of ore at Kakula with 6% copper content in Phase 1.

The Abu Dhabi National Oil Company (ADNOC) has awarded a $510 million engineering, procurement and construction (EPC) contract to Italy’s Saipem to expand production capacity at the Shah sour gas plant, as the UAE looks to increase its output of gas by 2030. The Optimum Shah Gas Expansion (OSGE) & Gas Gathering project has been awarded by ADNOC Sour Gas, a joint venture between ADNOC and US energy major Occidental. The contract will increase gas processing capacity at the Shah plant by 13% per cent to 1.45 bcf/d from 1.28 bcf/d by 2023 and supports ADNOC’s objective of enabling gas self-sufficiency for the UAE. The Shah gas plant currently meets 12% of the UAE’s total supply of natural gas, as well as producing 5% of the world’s elemental sulphur. The expansion will cumulatively represent a 45% increase on the plant’s original capacity of 1.0 bcf/d when it came on-stream in 2015.
