Title: Yasuo Ogawa: Innovator in Chemical Engineering
Introduction
Yasuo Ogawa is a prominent inventor based in Kawasaki, Japan, known for his significant contributions to the field of chemical engineering. With a total of 10 patents to his name, he has made remarkable advancements in various technologies, particularly in the production of acrylamide and heat pump systems.
Latest Patents
One of Yasuo Ogawa's latest patents is a method for producing acrylamide using a microorganism. This innovative method involves producing acrylamide from acrylonitrile through the action of a microorganism with nitrilase activity in an aqueous medium. The process is conducted in the presence of an alkali metal sulfate while controlling the pH of the medium between 7 and 9 using an alkali hydroxide.
Another notable patent is for a heat pump system designed to utilize a non-azeotropic refrigerant mixture. This system enhances heat transfer efficiency and minimizes pressure loss by incorporating a refrigerant extracting mechanism. This mechanism effectively removes refrigerant stagnating in the system, whether in vapor form in the condenser or liquid form in the evaporator, and returns it to the refrigerant circulating passage. The evaporator is constructed as a flooded type, particularly near the refrigerant outlet.
