Latest Patents

Berit Hillbrecht holds a patent for a method and system for producing crystalline calcium carbonate by the combined use of two gases with different CO content. This invention relates to a particularly energy-efficient, two-step method for the continuous or semicontinuous production of precipitated calcium carbonate (PCC). The process involves reacting calcium hydroxide, in the form of lime milk, with carbon monoxide (CO). In the first step, the CO source is exclusively flue gas with a CO content ranging from 4-25%. The second step involves the complete conversion of the lime milk reacted in the first step, achieving a maximum of 90% conversion, preferably between 10-90%, using a rich gas that comprises 30-99% CO, ideally utilizing biogas.
