GEA Messo PT has combined successfully its extensive evaporation and crystallization know-how with new research, to develop and establish innovative process solutions in the field of straight fertilizers. Messo-designed installations manufacture such compounds through new processing routes, such as recycling of by-products from waste management facilities, or by improving time-tested ones, as the reactive crystallization of granular ammonium sulphate from spent sulphuric acid and ammonia.
Besides granular production of ammonium sulphate, of newer methods of production of potassium chloride and potassium nitrate from ores, and the crystallization of ammonium sulphate and ammonium chloride from inductrial byproducts, GEA Messo PT has strong background in several niche activities. Messo crystallizers produce biuret-free urea, recover potassium sulphate (by metathesis) from sodium sulphate solutions, and more recently, combine the scrubbing of urea prilling tower exhaust gases with integrated recovery of ammonium sulphate-urea fertilizer mixtures.
GEA Messo PT plants, producing industrial-grade-quality straight fertilizers are found around the globe, from the Atacama desert of Chile to the European sylvinite and carnallite mines, and from the Dead Sea in the near East to caprolactam and methylmetacrylate facilities in Asia and North America.
