Title: Harold F. Porter: Innovator in Sodium Cyanide Processes
Introduction
Harold F. Porter is a notable inventor based in Hockessin, Delaware. He has made significant contributions to the field of chemical engineering, particularly in the production and shipment of sodium cyanide. With a total of 4 patents to his name, Porter has developed innovative processes that enhance the efficiency and safety of handling this critical chemical.
Latest Patents
One of Porter's latest patents is titled "Process for Shipment of Sodium Cyanide Slurries." This process involves manufacturing, shipping, and unloading a substantially solid, ice-like sodium cyanide dihydrate that contains essentially no liquid water. The method allows for a slurry of 58 weight percent or higher sodium cyanide to be rapidly cooled to the anhydrous/dihydrate transition temperature while minimizing the settling out of sodium cyanide crystals. The dissolution prior to unloading is achieved by adding heat and water or a dilute sodium cyanide solution. Another significant patent is "Process for Production of Sodium Cyanide," which describes a method for producing anhydrous sodium cyanide crystals. This process involves absorbing hydrogen cyanide synthesis gas containing oxides of carbon and water in aqueous sodium hydroxide and crystallizing the resulting sodium cyanide solution without removing the sodium carbonate formed during absorption.
