Title: Innovations of Yoshie Nakai in Phosphorus Removal Technologies.
Introduction
Yoshie Nakai is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of metallurgy, particularly in the area of phosphorus removal from industrial substances. With a total of 4 patents to her name, her work has implications for both environmental sustainability and industrial efficiency.
Latest Patents
One of her latest patents is a method for removing phosphorus from phosphorus-containing substances. This innovative method is designed for industrial applications and aims to effectively reduce phosphorus levels in materials used for metal smelting or refining. The process involves reacting the phosphorus-containing substance with a nitrogen-containing gas at a treatment temperature lower than the melting temperature of the substance. This reaction allows phosphorus to be removed in the form of phosphorus nitride (PN). Additionally, the method emphasizes controlling nitrogen and oxygen partial pressures to optimize the dephosphorization process.
Another notable patent by Nakai is focused on the dephosphorization of hot metal. This method involves adding a refining agent, which serves as both a lime source and an oxygen source, to hot metal in a holding container. The refining agent is characterized by an Ig-loss value ranging from 4.0% by mass to 35.0% by mass and must contain at least 60% by mass of quicklime. This innovative approach enhances the efficiency of the dephosphorization treatment.
Career Highlights
