Title: Dirkson D Liu: Innovator in Hydroconversion and Anemometry

Introduction

Dirkson D Liu is a notable inventor based in Ottawa, Canada. He has made significant contributions to the fields of hydroconversion and anemometry, holding a total of 2 patents. His innovative work has implications for both energy production and fluid dynamics.

Latest Patents

One of Liu's latest patents is focused on an antifoam to achieve high conversion in the hydroconversion of heavy oils. This process describes the conversion of heavy hydrocarbon oil in the presence of hydrogen and a catalyst or additive. It has been demonstrated that conversion rates can be enhanced by injecting an anti-foaming agent or a solution of this agent in light oil directly into the reactor. Remarkably, better results are achieved when the anti-foam or its solution is injected into the top section of the reactor.

Another significant patent is the multiple measuring control volume laser Doppler anemometer. This device includes a laser that provides an optical beam, which is transformed by an optical arrangement to create multiple measuring control volumes. Each control volume features two focused optical beams intersecting at a unique predetermined angle. A detector collects the scattered light from these measuring control volumes to determine the velocity at each control volume.
