Patent number: 9249305Abstract: This invention is based upon the discovery that activated carbon can be used to sequester polycyclic aromatic hydrocarbons that may be present in asphalt and creosote compositions. The treatment of asphalt and creosote compositions with activated carbon accordingly reduces the level of free polycyclic aromatic hydrocarbons in such compositions by sequestering them therein or removing them from the composition. After being sequestered the polycyclic aromatic hydrocarbons remain trapped in the asphalt or creosote composition, and are not available to the environment during normal processing into useful industrial products. This sequestration reduces the risk of exposing humans and the environment to the polycyclic aromatic hydrocarbons which would otherwise be free to migrate from the asphalt or creosote product during manufacturing and the service life of the product.Type: GrantFiled: October 3, 2014Date of Patent: February 2, 2016Assignee: Flow Polymers, LLCInventors: Aaron S.

The dry-separating system includes a dry separator, a circulating fan, and a cyclone deduster, which is used for separating dried raw coal into fancy coal, middling coal and coal gangue. A method for dry-separating and drying raw coal using the apparatus is also provided.Type: GrantFiled: November 19, 2010Date of Patent: June 3, 2014Inventor: Gongmin Li

Publication number: 20140144812Abstract: The present invention provides methods and systems for reducing moisture in mineral slurries, particularly mineral slurries containing minerals of small particle diameter, using a granular drying material. The invention also relates to novel mineral products and intermediates useful in connection with the process. The method and system reduced moisture by contacting the mineral slurry with the granular drying material. The granular drying material is selected to be readily separated from the dried minerals using a size separation technique such as a sieve screen. The granular drying material is the regenerated, preferably using a process involving heat exchange and cross-flow air. The granular drying material is preferably capable of regeneration and recycling in a continuous process with minimal attrition.Type: ApplicationFiled: March 15, 2013Publication date: May 29, 2014Applicant: NANO DRYING TECHNOLOGIES, LLCInventors: Richard W.

Publication number: 20140110621Abstract: Methods for purifying one or more value materials are provided. The method can include contacting an aqueous mixture comprising a value material and a contaminant with a dispersant and a depressant to produce a treated mixture. A weight ratio of the dispersant to the depressant can be from about 1:1 to about 30:1. The method can also include recovering a purified product comprising the value material from the treated mixture. The purified product can have a reduced concentration of the contaminant relative to the aqueous slurry.Type: ApplicationFiled: October 17, 2013Publication date: April 24, 2014Applicant: Georgia-Pacific Chemicals LLCInventors: Michael S. Kerns, Pablo G. Dopico, John B. Hines

Patent number: 8696770Abstract: The present invention relates to an apparatus and method for recycling coal ash comprising an unburned coal ash recovery unit and a lightweight aggregate manufacturing unit and is provided in an existing thermoelectric power plant and in which coal ash generated in the thermoelectric power plant is completely recycled for specific purposes using the coal ash recycling apparatus. According to the invention, the surrounding environment can be prevented from being contaminated during the transportation of waste to a recycling factory and transportation expenses can be reduced. Moreover, coal ash is completely recycled for specific uses, such that unburned carbon contained in the coal ash can be used. Also, coal ash can be recycled even as concrete admixtures having strict standards. In addition, the present invention can prevent environmental contamination caused by the landfilling of waste and recycle waste, thereby reducing the loss of land and the waste of resources.Type: GrantFiled: July 3, 2009Date of Patent: April 15, 2014Assignee: Ceragreen Co., Ltd.Inventor: Young Ho Jeong

Publication number: 20140069848Abstract: Disclosed herein is the use of differences in x-ray linear absorption coefficients to process ore and remove elements with higher atomic number from elements with lower atomic numbers. Use of this dry method at the mine reduces pollution and transportation costs. One example of said invention is the ejection of inclusions with sulfur, silicates, mercury, arsenic and radioactive elements from coal. This reduces the amount and toxicity of coal ash. It also reduces air emissions and the energy required to clean stack gases from coal combustion. Removal of said ejected elements improves thermal efficiency and reduces the pollution and carbon footprint for electrical production.Type: ApplicationFiled: November 17, 2013Publication date: March 13, 2014Applicant: Mineral Separation Technologies Inc.Inventors: Charles E. Roos, Edward J. Sommer, JR.

Patent number: 8662310Abstract: The invention relates to a method for increasing the concentration of platinum group metals in urban waste material. The method comprises obtaining particles of urban waste material; screening the particles of urban waste material by size,—selecting particles of urban waste material that lie within a defined size range; and processing the selected particles using at least one physical or chemical technique whereby to increase the concentration of platinum group metals to at least 5 ppm. The invention also relates to an apparatus for increasing the concentration of platinum group metals in particulate urban waste material. The apparatus comprises: a drying unit (4), a particle size screening unit (5); and one or more processing units for effecting platinum group metal concentration of the particulate urban waste material by physical and/or chemical techniques, in particular a magnetic separation unit (7) and a froth flotation cell (9).Type: GrantFiled: March 25, 2010Date of Patent: March 4, 2014Assignee: The University of BirminghamInventor: Angela Janet Murray
