Latest Patents

Among his latest patents, Jessup has developed a process for removing dioxane from a composition. This innovative apparatus utilizes an evaporator with an inlet chamber and heated channels. The process involves heating the composition upstream of a flow restriction to a temperature above the flashing temperature of water, while applying pressure to prevent flashing. Additionally, the process includes passing the heated composition through the evaporator and can involve injecting vapor into the channel. The end result is a purified, concentrated product that can be diluted to a desired concentration.

Another significant patent by Jessup is focused on the quantitative conversion of urea to ammonia on demand. This process includes receiving a demand rate signal for ammonia and feeding reactants, such as urea and water, into a reactor. By controlling the temperature and pressure within the reactor, a gaseous product stream containing ammonia and carbon dioxide is produced at consistent concentrations. This innovative approach also allows for the feeding of molten or solid urea into the reactor, enhancing the efficiency of ammonia production.
