20150045462 | VAPOR PHASE ASSISTED POST-CONSUMER POLYMER PROCESSING APPARATUS AND METHOD - Embodiments of the invention provide a process for processing post-consumer polymer. The polymer is contacted with a control medium having a carrier gas and a reactive vapor. Such a process is useful for processing post-consumer polymers with lower energy and reactants than with liquid reactants, and also promotes decontamination of the recycled polymer during the reaction. | 02-12-2015 |
20130326935 | SYSTEM FOR TREATING BIOMASS - A system and corresponding process for treating biomass, including by use of a plurality of pyrolysis treatment steps. The process can be used to provide a first pyrolysis product (e.g., intermediate), in the form of a carbon enriched material that contains substantially less hemicellulose content than the initial biomass, while substantially retaining and optionally enriching cellulose and/or lignin content as compared to the initial biomass. The process also includes a second pyrolysis device, adapted to further pyrolyze the first pyrolysis product in order to provide one or more gasses and/or vapors (e.g., providing condensable or non-condensable bio-products) and solid ash byproduct. The process also permits gasses and/or vapors that are generated in the course of its operation to be used in a variety of ways, including by: (a) recycling the gas/vapor into the system, in order to faciliate pretreatment (drying) of biomass, (b) condensing and recovering the gas/vapor or components thereof, and (c) venting or otherwise disposing of the gas/vapor. | 12-12-2013 |

20130019492 | SYSTEM AND METHOD FOR THE CONTINUOUS TREATMENT OF SOLIDS AT NON-ATMOSPHERIC PRESSURE - Systems and processes may be used for continuously processing a solid material at a non-atmospheric pressure. In some examples, the material is delivered to a process vessel at substantially the same non-atmospheric pressure condition as the process vessel so as to avoid shearing the material. In some examples, the solid material is continuously fed into a process vessel, continuously processed in the process vessel, and continuously discharged from the process vessel. | 01-24-2013 |
20120138511 | SYSTEM AND METHOD FOR THE TREATMENT OF OIL SANDS - Extraction of bitumen from oil sands may generate oil sands tailings mixed with a liquid. Systems may be used to separate the liquid from the tailings so the tailings can be disposed or otherwise reclaimed. In some examples, a system includes a primary separation vessel configured to receive oil sands tailings mixed with water and to separate the oil sands tailings into a plurality of layers, where at least one of the plurality of layers includes a mature fines tailing material. The system may include an apparatus configured to receive the mature fines tailing material from the primary separation vessel and to mechanically separate a portion of the water in the mature fine tailings material. The system may also include an apparatus configured to receive a concentrated oil sands tailings material and to thermally evaporate water from the concentrated oil sands tailings materials, thereby producing trafficable dried oil sands tailings. | 06-07-2012 |
20120103325 | SYSTEM AND METHOD FOR THE CONTINUOUS TREATMENT OF SOLIDS AT NON-ATMOSPHERIC PRESSURE - Systems and processes may be used for continuously processing a solid material such as a solid starch-bearing material at a non-atmospheric pressure. In some examples, the material is delivered to a process vessel at substantially the same non-atmospheric pressure condition as the process vessel so as to avoid shearing the material. In some examples, the solid material is continuously fed into a process vessel, continuously processed in the process vessel, and continuously discharged from the process vessel. | 05-03-2012 |
20110219678 | MOLD FOR FORMING COMPACTED MASS HAVING A GROOVED SURFACE - A mold for use in a rotary compactor in order to form compacted mass products (e.g., briquets) from a compactable material, the mold having at least one roll pocket that is provided with a surface configuration adapted to impart corresponding grooves to the respective mass surface, and in turn, to provide a physical barrier to the flow of the compactable material adapted to impart an optimal balance between releasability and wear resistance as compared to a pocket previously known in the art. | 09-15-2011 |

20090059714 | GRAVITY FLOW PROCESSOR FOR PARTICULATE MATERIALS - The present invention relates to purge vessel apparatuses and methods for processing particulate material composed of powder particles. Some such purge vessel apparatuses include a housing having first and second opposite ends and an inner surface defining a material path from the first end to the second end. Some such purge vessel apparatuses also include a gas exposure mechanism that is adapted to expose particulate material on the material path to a processing gas. Some such purge vessel apparatuses further include an agitating mechanism adapted to disrupt and/or inhibit formation of gas channels and/or to disrupt and/or inhibit formation of material flow channels by agitating particulate material on the material path, thereby exposing substantially all of the powder particles to the processing gas, while substantially maintaining mass flow. Several illustrative purge vessel apparatuses and method are disclosed for processing particulate material composed of powder particles. | 03-05-2009 |
