Title: Innovations of John B Johnson
Introduction
John B Johnson is a notable inventor based in Sedgefield, GB. He has made significant contributions to the field of chemical engineering, particularly in ammonia synthesis and gas separation technologies. With a total of four patents to his name, Johnson's work has had a considerable impact on industrial processes.
Latest Patents
One of Johnson's latest patents focuses on ammonia synthesis. This process involves creating ammonia synthesis gas from a raw gas that includes hydrogen, carbon dioxide, and medium boiling point gases, primarily nitrogen. The method utilizes a pressure swing adsorption process, ensuring that the volume ratio of hydrogen to medium boiling point gases is maintained between 1.25 to 2.5. This innovation emphasizes the purity of the product gas and the recovery of useful heat.
Another significant patent pertains to gas separation. In this invention, a raw ammonia synthesis gas, which preferably contains an excess of nitrogen, is transformed into synthesis-ready ammonia synthesis gas through two successive pressure swing adsorption (PSA) stages. The process includes the chemical removal of carbon monoxide, if present, and employs a system where waste gas from the second PSA stage is recycled back to the first stage for efficiency.
