Title: Dirk C Vermaire: Innovator in Phosphoric Acid Processing
Introduction
Dirk C Vermaire is a notable inventor based in Middelburg, Netherlands. He has made significant contributions to the field of chemical processing, particularly in the removal of hazardous materials from phosphoric acid. With a total of 2 patents to his name, Vermaire's work addresses critical environmental concerns.
Latest Patents
Vermaire's latest patents include a process and plant for removing lead, cadmium, and zinc from dusts produced in the electrothermal production of yellow phosphorus. This innovative method involves digesting the dusts with phosphoric acid containing at least 25% by weight of P₂O₅ at elevated temperatures in a ventilated reaction zone. The resulting digest solution is then filtered to separate an essentially lead-, cadmium-, and zinc-free solid residue from a phosphoric acid solution containing dissolved heavy metals.
Another significant patent focuses on the removal of lead and cadmium from phosphoric acid. In this process, an alkali solution and aqueous sulfide solution are introduced simultaneously into phosphoric acid with specific chemical properties. The temperature is carefully controlled to facilitate the precipitation of sulfides, which are then separated from the phosphoric acid.
