JET initiated the research and development of the EADS technology in August 1998 and has successfully addressed the ammonia slip and aerosol issues, which has been the key technical challenges of the ammonia-based desulfurization process.
The 4th generation of EADS technology is capable to meet the most stringent air quality regulations in the world at significantly lower lifecycle cost. The EADS technology delivers a 25-35% reduction in operating costs with no additional carbon dioxide (CO2) emissions.
As a green technology, The EADS process generates no wastewater or solid waste streams, while generating a saleable ammonium sulfate fertilizer by-product.
