Metso Outotec and thyssenkrupp Uhde have signed a Memorandum of Understanding (MOU) with Ma’aden in Saudi Arabia for developing a novel circular concept to improve the sustainability of Ma’aden’s phosphate operations.
The aim of the MOU is to design a groundbreaking integrated complex for processing of phosphogypsum, a waste by-product from phosphoric acid production, to reduce the amount of solid waste and allow the capture of CO2 emissions, Metso said in a statement posted on its website.
“The new circular process will be incorporated into Ma’aden’s phosphate operations to support the company in achieving their ambitious sustainability goals aligned with the Kingdom’s objectives,”
“We are honored to be part of this unique initiative. Decarbonization and circularity are relevant for all industries, and the new concept to be developed for phosphogypsum processing will be a major step forward in the fertilizer industry, contributing to efforts limiting global warming,” comments Hannes Storch, Vice President for Metals and Chemicals Processing at Metso Outotec.
For the development of this process, Metso Outotec’s extensive know-how and experience in the field of fluid bed and sulfuric acid solutions will be used.
The company’s portfolio includes plants based on elemental sulphur combustion and metallurgical off-gas handling, as well as plants for special processes such as the thermal decomposition of iron sulfate and spent sulfuric acid.
These are complemented by processes for the production of liquid SO2 and SO3, various concentrations of oleum, and special high-grade sulfuric acid.
Metso Outotec is a world leader in sulfuric acid plant design and implementation, with a successful track record stretching back over 90 years.
