Title: Innovations of Wilhelm Wengeler
Introduction
Wilhelm Wengeler is a notable inventor based in Bochum-Stiepel, Germany. He has made significant contributions to the field of phosphate rock treatment, holding a total of four patents. His innovative methods focus on the efficient conversion and treatment of phosphate rock, particularly those containing magnesium compounds.
Latest Patents
Wengeler's latest patents include a method for the treatment of phosphate rock that has a magnesium content exceeding 0.3%. In this method, crushed and screened phosphate rock is mixed with water in a 1:5 weight ratio. The mixture is then acidified with sulfuric acid, followed by filtration and washing before reaching the neutralization point. Another significant patent involves the conversion of magnesium-bearing phosphate rock into phosphoric acid. This process ensures that no difficult-to-dispose-of by-products are produced. The crushed rock is mixed with water and acidified with nitric acid, leading to a reaction product that is filtered and washed before neutralization. The wet and filtered rock is treated with nitric acid to produce phosphoric acid and a slurry of calcium nitrate tetrahydrate. The previously formed filtrate is combined with the calcium nitrate tetrahydrate slurry, which is then reacted with ammonia and carbonic acid to yield ammonium nitrate, magnesium carbonate, and calcium carbonate. These products are subsequently separated into an ammonium nitrate solution and a mixture of magnesium and calcium carbonates.
