Latest Patents

Fukunaka's latest patent focuses on a urea synthesis process and apparatus. In this innovative method, urea is produced by reacting ammonia and carbon dioxide within a specialized apparatus that includes a vertical condensation and synthesis column and a stripper. The process involves transferring a urea synthesis solution, which contains urea, unreacted ammonia, unreacted carbon dioxide, and water, from the top of the column to the stripper. Carbon dioxide is introduced at the bottom of the stripper, facilitating the separation of unreacted ammonia and carbon dioxide from the urea. This results in a mixed gas that is cycled back into the synthesis column, where it reacts with liquid ammonia to form urea. The uncondensed gases are absorbed in a medium that is recycled, enhancing the efficiency of the process.
