Successful Application of Clariant's New Ammonia Catalyst, AmoMax-Casale

On June 27th, Clariant announced that the new AmoMax-Casale catalyst, developed in collaboration with Casale, has been successfully utilized in Nutrien's plants in Trinidad and Tobago, Mosaic's plant in Louisiana, USA, and Yara's plant in the Netherlands.

Han Jie'an, Vice President of Clariant's Catalyst Business Unit for Synthesis Gas and Fuels, stated, "Ammonia will play a crucial role in future hydrogen energy ecosystems, and high catalytic activity and energy-efficient ammonia synthesis catalysts are essential for accelerating the achievement of net-zero emissions. AmoMax-Casale will also play a decisive role in promoting energy transition."

It is reported that AmoMax-Casale is a customized improvement based on Clariant's well-recognized AmoMax 10 catalyst, which has a successful operational track record in over 120 installations worldwide. The new AmoMax-Casale catalyst has been specifically optimized for Casale's reactor design, further increasing its efficiency index by up to 30% compared to AmoMax 10. In 2021, the AmoMax-Casale catalyst achieved its first commercial operation in Nutrien's ammonia plant in Trinidad and Tobago. The plant has already achieved annual energy cost savings of approximately $500,000 and a reduction of 4,700 tons of CO2 emissions per year. The second customer of AmoMax-Casale is Mosaic's plant in Louisiana, USA. After the modification of their ammonia plant, significant improvements were observed, including a decrease in operating pressure by approximately 12% and an increase in ammonia concentration at the reactor outlet by around 9%, showcasing the excellent performance of the catalyst and the new reactor.
