CS Combustion Solutions outlines retrofit options that use improved atomisation, air-side mixing and modular burner inserts to boost sulphur furnace reliability, flexibility and capacity with minimal equipment changes.

Germany's thyssenkrupp Uhde, working with Johnson Matthey, has completed a major ammonia converter revamp for İGSAŞ at its Kocaeli, Turkey, complex, restoring original nameplate capacity while cutting energy demand and pressure drop.

Maire Group subsidiary KTKinetics Technology says that it has completed work on the Rijeka Refinery Upgrade Project in Croatia, having completed the engineering, procurement and construction activities. The scope of work included a new delayed coking unit to process heavy residue and eliminate the production of fuel oil while increasing refinery efficiency capacity, the revamping of the process units and the utility network and the implementation of the latest solutions for coke handling and storage and sea jetty construction and shipping loading facilities.

Transformational beneficiation improvements are presented in this case study by Keenan Collins, Jayden Ladebruk and Edward DeRose of Hatch.

PT Pupuk Kalimantan Timur (Pupuk Kaltim) says that it has begun work on a revamp to its number 2 ammonia plant. The plant, which was originally constructed in 1984, has a capacity of around 1,500 t/d of ammonia. The revamp, which is being carried out internally by Pupuk Kaltim, aims to improve energy efficiency at the ageing plant and reduce carbon emissions, according to the company. The revamp is expected to extend the plant’s operational life, improve production reliability, and support Indonesia’s long-term fertilizer supply amid rising domestic demand.

thyssenkrupp Uhde says that it has successfully commissioned a hydrogen recovery unit (HRU) at the Fertil ammonia-urea plant in Ruwais, owned by Fertiglobe, a global exporter of urea and ammonia. The scope of work included engineering, procurement and site supervision during installation and start-up of the units.

KPI describes the systematic revamp of a Benfield CO2 removal unit at a high-throughput ammonia plant, emphasising simulation-driven diagnostics and customised engineering solutions.

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 Casale replaced the outdated boilers located downstream of the secondary reformer with three new double-tube type boilers supplied by Arvos.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.

NextChem subsidiary Stamicarbon has been selected to provide the process design package to upgrade the Hulunbuir New Gold Chemical Co., Ltd.’s urea plant in Hulunbuir, Inner Mongolia, using its proprietary NX STAMI UreaTM technology. The upgrade will integrate Stamicarbon’s EVOLVE MELT MP flash design to enhance operational efficiency and reliability while minimizing process steam consumption. Following the upgrade, the plant’s capacity will be increased by about 26% to 3,600 t/d, with an expected high-pressure steam reduction of 15%.
