Title: Shiao-Hung Chiang: Innovator in Environmental Applications
Introduction
Shiao-Hung Chiang is a notable inventor based in Pittsburgh, PA (US). He has made significant contributions to environmental technology through his innovative patents. With a total of 2 patents, his work focuses on improving processes related to waste treatment and mineral recovery.
Latest Patents
One of his latest patents is the "Multi-stage flotation column." This invention discloses an apparatus and method for environmental applications such as wastewater treatment, de-inking of recycled paper, chemical and biochemical waste clean-up, and mineral beneficiation. The design features a series of draft tubes arranged axially and separated by baffles, which provide individual mixing stages in the flotation column. A special gas distributor generates fine gas bubbles, creating a repetitive loop flow of the feed fluid in each flotation stage. This design enhances the uniform distribution of gas bubbles throughout the column, significantly improving the mixing and contact of gas bubbles with impurities that need to be removed.
Another significant patent is the "Process for removing mineral matter from coal." This process employs liquid carbon dioxide to remove mineral matter from feed coal. A water slurry of pulverized feed coal is mixed with liquid carbon dioxide, allowing demineralized coal to be collected in the liquid carbon dioxide phase while separated mineral matter concentrates in the water phase. The two liquid phases are then separately drawn off, and their solid contents are recovered.
