Latest Patents
One of his latest patents is titled "Method for withdrawing and dewatering slag from a gasification system." This invention relates to an apparatus and method designed to withdraw and dewater slag from a gasification system. The apparatus includes a conveying lockhopper that collects slag and other waste byproducts from the gasifier. The lockhopper is engineered to receive slag, extract and dewater it, and then expel the processed slag into a container for transport. The housing of the lockhopper is inclined, allowing for efficient movement of the slag through an auger or similar mechanism.
Another significant patent is "Ammonia injection for minimizing waste water treatment." This invention involves injecting ammonia into the stream of soot water exiting the gasification reactor. The elevated pH of the soot water helps retain more metals in the filter cake, thereby reducing the metals content in the grey water. This innovation allows for more grey water to be recycled back to the gasification unit, minimizing the burden on wastewater treatment facilities.
