Title: The Innovations of Hans M. Stonner

Introduction

Hans M. Stonner, an accomplished inventor hailing from Eschborn, Germany, has made significant contributions to the field of chemical engineering. With three patents to his name, he has played a crucial role in developing methods for recovering ammonia from aqueous effluents, showcasing his innovative approaches to environmental sustainability and resource recovery.

Latest Patents

Stonner's most recent patents include a method for recovering ammonia from an aqueous effluent that contains ammonia (NH₃). In this innovative process, an aqueous effluent is supplied to a total stripping column, where a mixture rich in NH₃, carbon dioxide (CO₂), and hydrogen sulfide (H₂S) is extracted as a head product. This mixture undergoes separation in an additional stripping column, resulting in a concentrated ammonia mixture and a mixture containing the sour gases CO₂ and H₂S. Further, the ammonia-rich mixture is scrubbed with liquid ammonia, enhancing the recovery process. The overhead product from the total stripping column is cooled in a condenser under a pressure of 1 to 7 bars, yielding a liquid phase that comprises 70 to 100% of the supplied ammonia. This liquid phase is then directed to a second ammonia stripping column, where a gas mixture rich in NH₃ is collected as a head product through scrubbing and condensation.

Additionally, Stonner has developed a process for treating aqueous effluent liquors from the gasification or de-gasification of coal. This innovative method involves extracting the effluents with a water-insoluble solvent, processing the extract to recover the solvent, and treating the aqueous residue to eliminate ammonia in a driving-off column.
