Decarbonisation in the sulphuric acid industry

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.

Nitrogen+Syngas 2025

CRU’s 38th Nitrogen+Syngas Expoconference will be held on 10-12 February 2025 in Barcelona. The most respected technical event for the global nitrogen and syngas community offers an ideal platform for industry professionals to connect, do business and learn about the latest innovations in operations, technology, process and equipment. The annual meeting attracts a global audience of producers, licensors and materials and equipment providers representing an unparalleled opportunity for business networking and peer-to-peer knowledge sharing.

Conversion into hybrid ammonia plants

One challenge of a green revamp by stepwise injection of green hydrogen into existing ammonia/urea complexes is to cover the nitrogen demand for the ammonia synthesis while stepwise reducing the front-end load, usually by applying a cost-intensive air separation unit (ASU). thyssenkrupp Uhde GmbH has developed an advantageous concept whereby, instead of an ASU, the nitrogen gap is closed by the introduction of pretreated reformer flue gas back into the ammonia process, with the side effect to also enhance CO2 production.
