A European ammonia plant, has successfully restarted following a revamp of the process gas cooling section, executed by Casale. Casale replaced the outdated boilers located downstream of the secondary reformer with three new double-tube type boilers supplied by Arvos. The new boilers were installed in the same location as the previous ones, minimising investment costs and plant modifications. The more robust and reliable design of the Casale-Arvos boilers has resulted in enhanced overall performance and reliability of the ammonia plant.

Maire Group says that its nitrogen fertilizer technology licensor Stamicarbon has been awarded new contracts related to its NX STAMI UreaTM technology in Canada. The first award is a process design package and the licensing of an integrated urea and diesel exhaust fluid (DEF) production plant currently being developed by Genesis Fertilizers, a farmer-owned consortium, at Belle Plaine, Saskatchewan. The plant will have a urea melt capacity of 2,500 t/d, with operations expected to begin by 2029. Also thanks to a carbon capture and sequestration unit, it will be the first proposed low-carbon nitrogen fertilizer plant in Canada. Stamicarbon will apply its proprietary flash urea melt technology to enhance operational efficiency and reliability while minimising process steam consumption. The plant will also include a DEF facility with a production capacity of 1,500 t/d.

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.

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.

This article dives into Chemetics’ rich history and key innovations that have shaped and moulded the industry.

Methanex Corporation has entered into a definitive agreement to acquire OCI Global’s international methanol business for $2.05 billion. The transaction includes OCI’s interest in two world-scale methanol facilities in Beaumont, Texas, one of which also produces ammonia. The transaction also includes a low-carbon methanol production and marketing business and a currently idled methanol facility in the Netherlands.

Transporting sulphur as a dry bulk solid can lead to it breaking into small particles which create dust. Over the years, various forming processes have been developed to try and minimise dust formation and produce the strongest, most resilient formed sulphur particles.

Join us at the CRU Sulphur + Sulphuric Acid 2024 Conference and Exhibition in Barcelona, 4-6 November, for a global gathering of the sulphur and sulphuric acid community. Meet leading market and technology experts and producers, network, share knowledge, and learn about market trends and the latest developments in operations, process technology and equipment.

With green ammonia from renewable energy facing cost hurdles to adoption, thoughts have turned to using nuclear energy as a carbon free alternative.

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.
