Title: Innovations in Urea Production by Keigo Sasaki
Introduction
Keigo Sasaki is a notable inventor based in Narashino, Japan. He has made significant contributions to the field of chemical engineering, particularly in the production of urea. With a total of 6 patents to his name, Sasaki's work focuses on improving the efficiency and sustainability of urea synthesis processes.
Latest Patents
Sasaki's latest patents include a process and apparatus for urea production that aims to enhance temperature distribution in submerged condensers. The first patent describes a urea synthesis process that involves synthesizing urea from NH3 and CO2 to generate a urea synthesis solution. By heating this solution, ammonium carbamate is decomposed, and a gaseous mixture containing NH3 and CO2 is separated. This process results in a solution with a higher concentration of urea. The use of a submerged condenser, which includes a shell and tube heat exchange structure, allows for the absorption and condensation of the gaseous mixture, generating steam through the heat produced during condensation. Additionally, a portion of the liquid obtained from the shell side is recycled back to the synthesizing process.
The second patent presents a novel process and apparatus for urea production that enables heat recovery from relatively low-temperature fluids. This process includes several steps: heat-exchanging steam condensate with another fluid to cool it, further heat-exchanging to raise the temperature of the condensate, and supplying the condensate to the condensation step for generating low-pressure steam. This innovative approach enhances the overall efficiency of urea production.
