Title: Innovations of John D Swift
Introduction
John D Swift is a notable inventor based in Hindhead, GB. He has made significant contributions to the field of chemical engineering, particularly in the production of methanol and para-xylene. With a total of 4 patents to his name, Swift's work showcases his innovative approach to solving complex industrial challenges.
Latest Patents
One of his latest patents is the "PSA process with reaction for reversible reactions." This process discloses a method for producing methanol from a synthesis gas stream comprising hydrogen and carbon dioxide. The innovation involves conducting the reaction and product separation in a pressure swing adsorption and reaction zone. This zone contains a uniformly distributed adsorbent for the selective adsorption of methanol and a catalyst for the equilibrium conversion of the synthesis gas to methanol. The process achieves methanol production by reacting hydrogen and carbon oxide while simultaneously adsorbing the product at the same temperature and pressure. The synthesis stream is then purged and depressurized to desorb the methanol product, resulting in higher conversion rates and reduced operational costs.
Another significant patent is the "Integrated selective adsorption and crystallization process for para-xylene." This innovation overcomes the eutectic limit of para-xylene crystallization by enriching the concentration of para-xylene in the crystallization feed. The process involves passing the feed stream through a selective adsorption zone, producing a para-xylene-enriched stream and a depleted stream. The depleted stream is then sent to an isomerization zone to re-equilibrate the xylene mixture, leading to additional para-xylene production. The enriched stream is directed to a crystallization zone, resulting in high purity para-xylene and increased overall recovery.
