Metso launches Cu POX leaching process for copper extraction industry - solution maximises copper recovery while reducing environmental impact
Days 2 and 3 of the CRU’s 38th Nitrogen+Syngas 2025 Expoconference turned to the technical sessions, organised in three parallel streams covering: green ammonia technology, nitric acid and ammonium nitrate, plant operations and reliability, urea technology, digitalisation, carbon capture, emissions reduction and sustainable fertilizer production, and fertilizer finishing.
Blue hydrogen has emerged as a crucial technology for decarbonisation as nations around the world work towards net-zero carbon targets. By decarbonising hydrogen production and exploring clean hydrogen sources we can fully harness the potential of hydrogen in the global energy transition. Johnson Matthey, Topsoe and Casale report on their strategies and advanced technical solutions for large scale blue hydrogen production.
Syngas generation units (SGU) represent a large portion of the capital and operational expenditure of ammonia plants and are critical from a mechanical reliability standpoint. Related capex/opex optimisation and mitigation of possible operational problems are key targets for ammonia plant owners. Giovanni Manenti introduces NITROQUENCH® technology which focuses on these key targets for ammonia SGU.
Toyo Engineering Corporation has developed two new digital solutions, MethaMaster™ and MethaDynamics™ , which enhance the operational efficiency of e-methanol production from variable renewable energy.
Marcus Weber of Fluor discusses degassing units for large scale sulphur recovery units, evaluating the pros and cons of various available commercial technologies with the emphasis on mega size sulphur recovery units and focussing on how technology can lower degassing capex via economy of scale for new facilities or existing facilities undergoing expansion.
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.
In Part 3 of this series on stripper efficiency issues, we continue the discussion on some some of the many causes of lower stripper efficiency. Here we discuss liquid divider fouling and bad installation of liquid dividers.
Urea revamp activities are performed to achieve improvements of the urea plant. Besides the typical capacity increase there are many options to reduce operation costs, increase plant availability or reduce environmental impact. In this article Marc Wieschalla of thyssenkrupp Uhde GmbH provides an overview of some of the options from an EPC contractor point of view.
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.
