Casale to design new ammonia converter for Yara facility

Published by , Editor
World Fertilizer,

Casale has said it will redesign its Ammonia Converter currently in operation at a fertilizer plant operated by Yara in Herøya, Norway.

The existing plant will be converted by replacing the current hydrogen production process through liquefied fossil gas with green hydrogen based on renewable energy. By so doing, Yara will be able to create emission-free ammonia.

As part of this initiative, Casale has committed to applying its own technology, including the design of brand-new ammonia converter internals. Furthermore, Casale is designing its reactor in order to let the Herøya plant synthesis loop be able to initially work with the traditional source. After the decarbonisation of the plant, the Casale design of the reactor will allow the ammonia synthesis to switch to the new source of green hydrogen without any additional intervention.

In this first decarbonisation step, the plant will produce enough hydrogen equivalent to 20 500 tpy of green ammonia, which converts into between 60 000 and 80 000 t of green fossil-free mineral fertilizer.
