Casale’s integrated revamp solutions for ammonia and urea plants are designed to unlock latent potential and boost operational performance.

Stamicarbon is pioneering future-proof solutions for low-carbon production with two ammonia process designs.

Revamping existing urea plants can deliver significant improvements – including higher capacity, lower costs and reduced emissions.

Casale has signed two contracts with Xin Lian Xin Chemicals Group Co.,Ltd for the implementation of ammonia and urea technologies in the company’s new urea complex in Henan province. Capacities for the two plants will be 2,700 t/d of ammonia and 3,500 t/d of urea. Casale says that the complex will be its first grassroots […]

AMETEK Process Instruments has collaborated with Worley Comprimo, part of Worley’s Technology Solutions, to provide sulphur recovery unit (SRU) stakeholders with critical analytical measurements combined with advanced burner control technology to deliver enhanced automated air control management. The companies say that their 2ACT™ Solution is a fully automated system that minimises SRU upsets, enhances reliability, and delivers strong returns on investment. At the heart of this partnership, the innovative 2ACT™ Solution offers an all-in-one approach to advanced air control – significantly boosting SRU performance and efficiency while reducing operational costs. 2ACT uses AMETEK’s IPS-4 ultraviolet and infrared analyser to measure H2 S, CO2 , NH3 , H2 O and total hydrocarbons (THCs) by continuously sampling the acid gas upstream of the SRU. The change in air demand requirement is then calculated, with main and trim air adjustments implemented automatically by the feed forward control scheme designed by Worley Comprimo. The companies say that the benefits of the 2ACT Solution include maintaining an optimal H2S to SO2 ratio at the outlet of the Claus Plant to maximise recovery efficiency, mitigating damage to tail gas treatment unit (TGTU) components, lowering SO2 emissions and carbon footprint with improved uptime and plant throughput.

Topsoe has been selected by Zhongneng Yida New Energy Co., Ltd to deliver technology for production of sustainable aviation fuels (SAF) at a new facility to be located at the city of Shijazhuang in the Shenze Economy Development Zone of Hebei province. Zhongneng Yida plans to export the produced SAF to European and local Chinese markets. Topsoe will provide its HydroFlex® technology and catalysts as part of the agreement. The facility will produce 400,000 t/a of SAF, utilising used cooking oil for the feedstock.
