Sepn. of different scrap plastics by flotation - includes sepg. pelletised plastic in fluid-contg. tank with high energy stirrer, for e.g. polystyrene

Agglomerations of small plastic particles, esp. film and adherence of air bubbles is detrimental to sepn. quality. High energy stirrer is used to create turbulence to break up the agglomerations and release air bubbles. Actual sepn. of material occurs when the stirrer is switched off. Lighter material rises to the surface of the fluid and heavier material falls to the bottom. Appts. for sepn. comprises tank with high energy stirrer, outlet valve for heavier material in the base and overflow trough for removing lighter material at the surface. Process fluid is recirculated via valve producing laminar flow into the tank. USE/ADVANTAGE - The process separates different types of scrap plastic e.g. polystyrene, polyvinyl chloride, polyethylene from each other and improves purity of separation by breaking-up agglomerations and removing adhering air bubbles.

Systems for recovering the target material can comprise an extractant formulation comprising a light hydrocarbon solvent and a high molecular weight hydrophobic polymer, wherein the extractant formulation is mixable with the aqueous stream in a mixer to form an admixed solution having a hydrophobic portion and an aqueous portion, with the target material partitioning to the hydrophobic portion; a separator for isolating the hydrophobic portion from the aqueous portion; and a collector to which the hydrophobic portion is directed, wherein the target material is recovered from the hydrophobic portion.

Films containing foamable inks or coatings and process for separating similar density materials

The present invention is directed to films that are deposited with foamable inks or coatings. One purpose is to facilitate their separation for recycling purposes. The films are particularly useful as packaging labels. The inks/coatings are designed so that foaming is activated when the film is in the hot-wash stage of a typical recycle process. This provides added buoyancy to the film allowing it to float to the surface and be removed, thereby significantly improving the efficiency of the recycle process. A feature of the invention is that, prior to this hot wash, the inks/coatings remain substantially unfoamed and thereby do not negatively affect the aesthetics of labeled package. The foamable inks/coatings can be used with any type of film.

GREEN METHOD FOR PRODUCING A MIXTURE OF MULTIPLE NANO-CARBON POLYMORPHS FROM COAL

The present disclosure relates to a green method for producing and exploiting multiple nano-carbon polymorphs from coal commonly known as anthracite, meta-anthracite, and semi-graphite. The method disrupts the prevalent environmentally unfriendly practices of burning coal with poor profitability and sustainability because the method yields an unexpectedly rich mixture of high-performance nano-materials, comprising carbon nano-fibers, carbon nano-tubes, carbon nano-onions, nano-graphite-plates, and nano-graphene-disks, by simply mechanically-comminuting coal to nano-size, with minimal sorting efforts. The resulting total-yield of nano-carbon polymorphs is over 50% by weight from properly selected coal. Innovative means are added to the prevalent comminution and sorting practices to further reduce energy and chemical consumption. More importantly, the method also refines the comminution and sorting details for producing the best custom-made formulations. This holistic engineering approach eliminates unnecessary separation and sorting steps because a custom-made formulation typically requires blending the sorted components. Formulations with mixed nano-carbon polymorphs are engineered as new and high-valued-added composite ingredients to critically raise the performance of cement-based, polymer-based, and metal-based composites. 1. A method for extracting from coal more than one nano-carbon polymorphs , wherein the method uses no oxidation nor any chemical etch but uses environmentally friendly processes comprising:the selection of a proper coal source;dry mechanical pulverization of the selected coal;float-sink separation of organic constituents from inorganic mineral constituents;wet-comminution of the separated organic constituents to 200-1000 nm with no grinding grit;follow-up wet-comminution of the sub-micron comminuted organic constituents, with the assistance of grinding agents, to yield nano-carbon polymorphs smaller than-100 nm;sorting of multiple nano-carbon ...

Process for recovery of corn coarse fiber (pericarp)

A method of recovering corn coarse fiber by flotation, which features the use of a hydrocyclone, or other separating machinery, in which the specific gravity of the slurry contained therein has been increased to approximately 12-14 Baumé so that the corn coarse fiber is of a lighter density than the remainder of the slurry. Therefore, the corn coarse fiber can be separated from the remainder of the slurry because it floats to the top of the slurry. If the present pericarp recovery process is added to a modified dry-grind ethanol production line, a high value co-product (the pericarp) is added to the other co-products and the end-product of ethanol, which can all be sold, and the economic efficiency of the plant is increased. More specifically, the present invention provides a process for recovering corn coarse fiber including the steps of: soaking corn in water to loosen the attachments of various grain components therein to each other, degerminating the soaked corn to strip the corn coarse fiber and the germ away from the endosperm, recovering the germ, and recovering the corn coarse fiber by flotation.

SUBSTANCE: method of separating the hydrophobic particulate material and its hydrophilic contaminant dispersed in the aqueous suspension comprises the following steps: a) stirring the aqueous suspension under high shear mixing conditions in the presence of the first hydrophobic liquid to form agglomerates of the hydrophobic particulate material; b) separating the agglomerates from the aqueous liquid and the dispersed hydrophilic contaminant; c) dispersing the agglomerates separated from the aqueous liquid and the dispersed hydrophilic contaminant in the second hydrophobic liquid such that water trapped between the particles constituting the said agglomerates is released from the hydrophobic particles; and d) separating the hydrophobic particles from the second hydrophobic liquid and water released from the said agglomerates, thereby obtaining hydrophobic particles substantially free of hydrophilic contaminant and water. The method for removing water trapped in a filter cake from hydrophobic particles comprises the steps of: a) dispersing the filter cake in a hydrophobic liquid such that the entrained water is released; and b) separating the hydrophobic particles from the hydrophobic liquid and released water, thereby obtaining hydrophobic particles substantially free of hydrophilic contaminant and water. EFFECT: increasing the efficiency of separation of hydrophobic material, as well as the removal of water. 20 cl, 2 dwg, 11 tbl, 11 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 644 181 C2 (51) МПК B03B 5/28 (2006.01) B03D 1/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК B03B 1/04 (2006.01); B03B 5/28 (2006.01); B03B 9/00 (2006.01); B03B 9/005 (2006.01); B03D 1/00 (2006.01); C10L 1/324 (2006.01); C10L 1/328 (2006.01) (21)(22) Заявка: 2014152482, 11.06.2013 11.06.2013 (73) Патентообладатель(и): ВИРГИНИЯ ТЕК ИНТЕЛЛЕКТУАЛ ПРОПЕРТИЗ, ИНК.
