Title: Innovations by Inventor Ying H Li
Introduction
Ying H Li is a notable inventor based in Plano, TX (US). He has made significant contributions to the field of environmental technology, particularly in the treatment of hydrocarbon-contaminated materials. With a total of 6 patents to his name, his work focuses on innovative methods for processing crude oil sludges and other contaminated materials.
Latest Patents
One of Ying H Li's latest patents is an apparatus for treating crude oil sludges and similar heavy hydrocarbon liquid sludges. This invention involves mixing these sludges with diatomaceous earth or perlite to create a friable and flowable solids mixture. This mixture is then conveyed to a combustion unit, such as a rotary kiln or calciner, where the hydrocarbons are combusted to produce gaseous combustion products and a substantially hydrocarbon-free solids mixture. The solids discharged from the combustion unit can be recycled back into the mixing process, reducing the sludge to a friable material for further treatment.
Another significant patent addresses the treatment of sludges and soil materials contaminated with hydrocarbons. In this system, oily sludges containing volatile hydrocarbons are mixed with diatomaceous earth or perlite in an indirect dryer that vaporizes liquids with a boiling point of less than about 700°F. The dried solids are then conveyed to an oxidation unit, where they undergo further processing. This system can also be adapted to treat hydrocarbon-contaminated soils and other earth-like materials with varying particle sizes.
