Latest Patents
One of his latest patents involves the treatment of waste sludge to produce a non-sticking fuel. This process subjects a waste sludge containing water, oil, and solids to filtration under vacuum or applied inert gas pressure, preferably no more than 50 psia, while utilizing a filter aid. This method retains the maximum amount of oil in the filter cake, which is then dried at a relatively low temperature to selectively remove water and produce a high heating value non-sticking solid. The resulting product is suitable for use as a solid fuel in cement kilns or other combustion facilities. The applied pressure can be varied to retain different amounts of oil, thus producing different heating values in the final solid fuel.
Another significant patent by Humbert H Chu focuses on cyanide removal from oily solid waste using a solvent extraction process. This innovative process is performed in a single processing zone where multiple steps are carried out to remove contaminants. These steps include reducing the size of the contaminated oily solid waste, adjusting its pH, dewatering or deoiling the waste, and drying the resulting solid. The dried solid is then extracted with an organic solvent, followed by further drying to remove residual moisture, cyanide, solvent, and volatile organics.
