| 141 | METHOD FOR SEPARATING UNDESIRED COMPONENTS FROM COAL BY AN EXPLOSION TYPE COMMINUTION PROCESS. | EP81900897 | 1981-03-04 | EP0047310A4 | 1985-09-26 | MASSEY LESTER G; BRABETS ROBERT I; ABEL WILLIAM A |
| Process for the fractionation of a porous or fluid-permeable hydrocarbonaceous solid, such as coal, containing an admixture of mineral matter and hydrocarbonaceous matter, into a separate mineral enriched fraction and a separate hydrocarbonaceous enriched fraction. In this process, the hydrocarbonaceous matter solid is comminuted to convert the hydrocarbonaceous matter in the coal into discrete particles having a mean volumetric diameter of less than about 5 microns without substantially altering the size of the mineral matter originally present in the coal. As a result of this comminution, the hydrocarbonaceous particles can be fractionated from the mineral particles to provide a hydrocarbon fraction having a lesser concentration of minerals than in the original uncomminuted material and a mineral fraction having a higher concentration of minerals than in the original uncomminuted material. A preferred method for comminuting the porros or fluid-permeable hydrocarbonaceous solid, i.e. coal, is to first form a slurry of coal and a fluid such as water or methanol. This slurry is then heated and pressurized to temperatures and pressures in excess of the critical temperature and pressure of the fluid. The resultant supercritically heated and pressurized slurry is then passed to an expansion zone maintained at a lower pressure, preferably about ambient pressure, to effect comminution or shattering of the solid by the rapid expansion or explosion of the fluid forced into the coal during the heating and pressurization of the slurry. The supercritical conditions employed produce a shattered product comprising a mixture of discrete comminuted hydrocarbonaceous particles having a volumetric mean particle size equivalent to less than about 5 microns in diameter and discrete inorganic and mineral particles having a mean particle size substantially unchanged from that in the original solid. This mineral fraction, in turn, is then fractionated from the hydrocarbonaceous fraction. The product hydrocarbonaceous fraction has a lower density, greater solvent solubility and different reactivity to oxygen than does the feed solid. This hydrocarbonaceous fraction also includes a subfraction of particles having a mean particle size, by volume distribution, equivalent to less than about 2 microns in diameter which contain substantially no sulfur compounds. | ||||||

| An autoclave (2) is charged with waste material to be treated and supplied with steam from a steam accumulator (18) to produce in the autoclave a temperature in excess of 130° C at a pressure in excess of 2 bar for at least 20 minutes whilst the waste material is processed. The autoclave rotates and vanes (31) in its interior, together with said rotation, help the steam to treat the material, which after removal from the autoclave is conveyed to a rotary screen (3) to separate out particles of the treated material having a size less than 25 mm. A steam generation system incorporating the steam accumulator is preferably used with the autoclave to allow the waste material to operate efficiently. | ||||||

| The invention is refered to the technology of obtaining solid dry materials, in particular, to the methods of getting dispersed-conditioning powder materials. It can be used in mining and construction industry. According to the invention, the method of getting dispersed-conditioning material, including electromagnetic conditioning of material polyfractional mechanical mixture, its separation, and collection of finished powder material, involves the conditioning by grinding conditioning mixture under its electroneutralization conditions. To achieve this, the conditioning mixture is undergone by electrical insulation with setting off the depolarizing electric potential in material polyfractional mechanical mixture. Here, the electric potential is in 10.0 60.0 range. | ||||||
| 149 | METHOD AND APPARATUS FOR EXTRACTING PLANT RESINS | EP98907619 | 1998-02-24 | EP1015118A4 | 2002-08-07 | DELP REINARD C |
| An improved method and apparatus for extracting resin from plant material. Conventionally, plant resins, which are useful in many products, are extracted using chemical solvents, which may alter the extract, and may produce a byproduct or residue that may be unusable or problematic. The present invention overcomes these drawbacks by using cold water in a wash process to cause the resins to become brittle, while the remaining plant material becomes more flexible. Separation is accomplished using an extractor (10) having a washing chamber (12) with an open top (14) and a screen filter (16) disposed above a settling chamber (18). A collection bottle (24) is placed below a valve (22), and may include a filter (26) to separate resin particles from the solute. The washing chamber is first filled with cold water and then a quantity of plant material (P) is placed therein, followed by an ice layer (30). An agitator (32) is then actuated to mix the contents to separate the resins. The settled resin is thereafter captured by the filter (26) upon opening the valve (22). | ||||||

| A method of recovering the different components of multiple layer materials, for instance consisting of pieces (20) of paper, plastic and aluminium foil, comprises delivering the material to the infeed zone (4) of a refiner or disperser (2) that includes mutually opposing discs (5; 6) which include material engagement surfaces or material engagement elements (5a; 6a) and which rotate relative to one another. The gap between the discs (5; 6) is adjusted so that the material present therebetween will be subjected to shear forces that result in rapid mutual separation of the various layers of material. Separated pieces (20'; 20'') of the various layers are pumped in the form of a suspension to a horizontal, rotating, perforated drum (3) which includes an inner screw feeder and to which further suspension or dilution liquid is supplied. Suspended readily slushed or pulped material pieces depart through perforations (3a), whereas layer material (20'') that is not readily slushed or pulped is discharged through one end of the drum. The invention also relates to plant that operates in accordance with the inventive method. | ||||||
| 151 | IMPROVED APPARATUS AND METHOD FOR PROCESSING MUNICIPAL SOLID WASTE | EP00936240.1 | 2000-05-24 | EP1196255A1 | 2002-04-17 | GARRISON, Roy; MALLEY, Donald |
| The present invention relates to an apparatus and method for separating and processing solid waste, often but not necessarily from municipalities (and so will be generically referred to herein as municipal solid waste or "MSW"), into useful products, and for reducing biohazards and putrid odors derived from MSW. The MSW is loaded into an elongated, generally cylindrically shaped rotating pressure vessel and is subjected to heat and pressure by the application of steam in specified amounts to break down the organic portion of the MSW into a cellulose feedstock, or a de-manufactured paper product, of uniform particle size and density. This product is then easily separable from other constituents of MSW, such as glass, aluminum and other metals, and plastics. The recyclables are recovered and sold in the market. The waste water from the process is reduced by processing through a water vamping apparatus. The apparatus and process disclosed herein, unlike any in the prior art, allows for an economically and technically viable industrial process and environmental solution, which have the potential to replace current landfill technology. | ||||||

| The invention concerns a process for the separation of viscoplastic materials such as plastics and rubber from materials, particularly paper, which can be shredded and defibrated by mechanical action, and a device to carry out the process. The process is chararcterised in that the mixture of the materials to be separated is subjected to radial, axial and tangential acceleration forces, with a mass flow of comminuted fibrous material and another mass flow of essentially intact plastic materials being drawn off separately. The device for carrying out the process consists of a strainer basket (1) of cylindrical or preferably polygon shape, the outer casing of which is provided with holes (2) to allow the fibrous materials to pass through. The inside of the strainer basket is provided with a coaxial drive shaft (3) with preferably rigidly mounted blades (4). | ||||||

The present invention refers to a process and relative plant for the disposal and recycling of waste, both of urban and industrial origins. The process and plants are based on cryogenic technology, that is on the principle of putting waste into contact with a cryogenic fluid, with the aim of weakening, separating and reducing in volume the waste to be disposed of and recycled. The process is intrinsically non-polluting, it permits the elimination and also the recycling of treated waste in the form of fertilisers, fuel, or as industrial material. |

| In a method of treating composite elements of solid organic and/or inorganic composite active substances - such as metal/metal, plastics/plastics or metal/plastics composites or mineral composites containing metals and/or plastics - solid particles are produced from the composite elements and added to a conveying fluid. At least one flow obstacle, such as a separating edge, disposed transversaly to the flow of the mixture of solid particles and conveying fluid, is moved relative to said flow in order to form eddies which accelerate and break up the mixture. The mixture is fed to the separating or breaking-up process at the separating edge(s) at an acceleration of 20 to 25 m/sec2 and the composite element is preferably desintegrated before the separating or breaking-up process. | ||||||
