New concepts focused on the transfer and combination of existing sulphur and sulphuric acid technologies to support decarbonisation of the sulphuric acid industry are being investigated. In this article three research projects are discussed: sulphur dioxide depolarised electrolysis for green regeneration of spent acid, use of renewable heat and catalyst to the splitting process from sulphuric acid to SO2 for reduction of fossil fuel consumption, and sulphur as an energy vector.

We look ahead at fertilizer industry prospects for the next 12 months, including the key economic and agricultural drivers likely to shape the market during 2025.

12 Dec 2024 On 8 December, Syrian rebel forces led by Islamist group Hayat Tahrir al-Sham (HTS) ousted the government of Bashar al-Assad. The now thirteen-year long civil war in the Middle Eastern nation has proven hugely disruptive to its phosphate rock production. During the 2020s exports recovered strongly amid Russian intervention and a lull […]

NextChem has been awarded two contracts to upgrade and expand the capacity of the Heydar Aliyev Oil Refinery (HAOR) industrial complex in Baku by state oil company SOCAR. As part of the contract, NextChem will conduct a technological assessment and deliver a process design package to upgrade the existing sulphur recovery unit (SRU) with oxygen enriched air, a cost-effective and flexible solution for expanding its current sulphur production capacity. Additionally, NextChem will provide the licensing and the process design package based on its proprietary NX SulphuRec TM technology for a new SRU. NX SulphuRec TM is a portfolio of proprietary sulphur recovery technologies, based on the integration of modified Claus and tail gas treatment processes, aimed at reducing the environmental impact of acid and sour gases produced during the refining process.

Beyond its use in the manufacture of sulphuric acid, sulphur dioxide also has many industrial uses, especially in the food, paper, pharmaceutical and refining industries.

Sachin Nijhawan has been appointed as the new CEO of thyssenkrupp nucera US, and Juergen Grasinger was named Chief Operating Officer to advance the company’s international growth strategy and expand its global leadership in the manufacturing and supply of hydrogen production technology. Based out of the thyssenkrupp’s Houston office, Nijhawan will be responsible for the business activities of the US operations.

One of the key challenges of producing RFNBO (renewable fuels of non-biological origin) compliant ammonia is managing the intermittency associated with renewable energy sources for hydrogen production. Furthermore, the additional costs associated with managing this intermittency can be significant. In this article, Dr Solomos Georgiou of AFRY Management Consulting explores those additional costs as well as potential ways to achieve cost savings and make RFNBO-compliant ammonia production competitive against conventional ‘grey’ ammonia.

As the oil and gas industry focus on new requirements for CO2 recovery, cryogenic processes come under the spotlight. Mahin Rameshni and Stephen Santo of RATE USA discuss the importance of cryogenic processes in acid gas sweetening. Liquefied H2 S and CO2 reinjection is proposed as a cost effective alternative to large sulphur plants.

Revamping aging urea plants with the latest urea technology brings many benefits. Not only can greenhouse gas emissions be reduced, but the overall performance and sustainability of these facilities can also be optimised. Hiroo Kunii of Toyo Engineering Corporation discusses TOYO’s approach to urea plant revamping.
