Casale Ammonia converter engineered for an environmentally friendly plant


23 February 2022

Casale is committed to study the application of its technology, mainly in connection with the well know state-of-art Casale Ammonia Converter, to a Yara ammonia factory at Herøya (Norway). The existing plant, being one of the sources of CO2 emissions in Norway, is assessing the opportunity to replacef the current hydrogen feedstock via liquefied fossil gas, with  “Green Hydrogen” based on renewable energy, in view of obtaing emission-free Ammonia. As part of this initiative, Casale is studying to apply its own technology, including the design of a brand-new ammonia converter internals. Casale is committed to deliver better conversion reactors, intrinsically providing GHG emission reduction. Furthermore, Casale is designing its reactor in order that the Herøya's  synthesis loop be able to initially work with the traditional feedstock. After the decarbonization of the plant, the Casale  reactor will allow  switching directly to the new source of green hydrogen without any additional modification. In this first decarbonization step, the plant will produce enough hydrogen equivalent to 20,500 tonnes of green Ammonia per year, which will be converted into  60,000 to 80,000 tonnes of green, fossil-free mineral fertilizers.
