Title: The Innovative Contributions of Edward K Liu
Introduction
Edward K Liu is a notable inventor based in Houston, TX, who has made significant contributions to the field of technology through his innovative patents. With a total of 3 patents, Liu has focused on processes that enhance efficiency and reduce environmental impact.
Latest Patents
One of Liu's latest patents is a process and apparatus for the removal of oxygen from seawater. This invention aims to reduce the dissolved oxygen content in seawater from about 8 ppm to 10 ppb or less. The process utilizes a separator in horizontal alignment to maximize gas-liquid contact area, thereby increasing throughput. Additionally, heating seawater to temperatures between 30°C and 60°C enhances the removal of oxygen. The use of once-through fuel gas as a stripping gas, which is subsequently combusted for heating, contributes to high efficiency and minimizes fouling. This innovative combination allows for the reduction of residual oxygen in deoxygenated seawater to below 10 ppb, and as low as 2 ppb.
Another significant patent by Liu involves an ebullated bed process with a recycle eductor. In this process, the feedstock conduit is maintained at a pressure of at least 50 psi in excess of the liquid-vapor separation pressure. This excess head is utilized in conjunction with an eductor to recycle reactor effluent liquid, maintaining the expanded catalyst bed at 110% of the settled catalyst volume without the need for a separate pump.
