Abstract:
A method of transporting solid refinery waste includes loading solid refinery waste into a mobile tank having at least one sloped floor wall and a plurality of compartments separated by at least one buffer. The method may also include maintaining a head space between a top level of the solid refinery waste and a top wall of the mobile tank. The method may also include delivering the mobile tank to a burning facility that maintains a reserve of diluent and that is equipped with an agitator configured for lowering into the mobile tank through a manhole opening, to thereby permit the diluent to be conveyed into the headspace and mixed with the solid refinery waste, thereby enabling a resulting mixture to be off-loaded for burning at the burning facility.
Abstract:
The subject of the present invention is a method for processing metallized packaging materials, especially beverage cartons, or blister packaging.According to the invention, the aluminum is dissolved with the aid of acid and separated from the plastic. The metal-containing acid solution then undergoes pyrohydrolytic treatment and the acid is thus recovered. The aluminum can be recovered as valuable aluminum oxide.
Abstract:
A method and apparatus for treating waste materials comprising, particulating the waste materials into discrete particles, heating and drying the particles in a non-oxidizing atmosphere in a drier at a temperature in the range of 800° to 860° C. for carbonizing the particles, crushing the carbonized particles and leaching the crushed carbonized particles in an acid solution for dissolution of heavy metals into the solution, separating the leach solution containing heavy metal from the carbonized particles, adding to the carbonized particles particulate sodium hydroxide, silica, feldspar and limestone in a ratio of 100:0.3-0.5:8-12:2-4, mixing said particles with 15 to 18% by weight water to form a wet mixture and continuously extruding the wet mixture to form an elongated continuous extrusion, severing the elongated extrusion into blocks or planks of predetermined length, drying the blocks or planks and heating the dried blocks or planks in a kiln at a temperature in the range of 1200° to 1300° C. for a time sufficient in an oxygen deficient atmosphere to sinter the blocks or planks and to form carbides, and separating and recovering CO2 gas from combustion gases in the kiln.
Abstract:
Waste or organic material is compressed at a pressure sufficient to burst cells, for example 50 bar or more, and separated into a dry fraction and a wet fraction. The wet fraction is treated in an anaerobic digester to produce biogas after removing grit. The wet fraction is diluted, preferably with sludge, before it is degritted. Optionally, floatables are removed from the fraction before it is added to the digester.
Abstract:
An aircraft collapsing device that collapses a fuselage of an aircraft inward, the system includes a gate-shaped shell formed to cover a circumference of both sides and an upper portion of a fuselage of an aircraft body from which horizontal wings and a vertical wing have been decoupled; a wedge-shaped pressing member that is mounted on an upper portion of the shell to press at least one portion of a circumference of at least one of annular frames juxtaposed in a longitudinal direction of the fuselage toward a center of the fuselage; a pair of sidewall pressing members that is mounted on both sides of the shell to press the fuselage simultaneously from two directions crossing a pressing direction of the wedge-shaped pressing member at the center of the fuselage after pressing by the wedge-shaped pressing member; and a moving unit that moves the fuselage of the aircraft and the shell relative to one another, wherein each of the pair of sidewall pressing members includes a plate-shaped pressing plate, and a projection member extends in a longitudinal direction of the fuselage and is formed on the pressing surface side of the plate-shaped pressing plate.
Abstract:
A wasted carpet and felt scrap recycling apparatus is provided. The waste carpet and felt scrap recycling apparatus includes a feeding unit that feeds a cut scrap while forming a feeding path and a supply unit that is connected to the feeding path and supplies the scrap that passed the feeding unit along the feeding path while pressing the scrap. A separation unit is spaced apart from the supply unit, and provides a frictional force to one surface of the scrap supplied from the supply unit through rotation of the supply unit and separates the scrap into fiber and recycled material.
Abstract:
A food waste management system includes a tank having an internal chamber for containing food waste and sufficient water for fully submersing the food waste. The system further includes a water supply system for supplying water to the internal chamber, a gas supply system for supplying a gas to the internal chamber, a discharge system for discharging water and food waste from the internal chamber, a grinder system for grinding the food waste, the grinder system being disposed in the internal chamber to be fully submersed in the water, a circulation system disposed in the internal chamber for circulating water and food waste and a control system for controlling operation of the food waste management system in accordance with a desired control process. The system further includes a nutrient additive to be supplied to the internal chamber in predetermined amounts at predetermined intervals.
Abstract:
An aircraft collapsing device that collapses an aircraft fuselage inward includes: a gate-shaped shell which covers a circumference of both sides and an upper portion of a fuselage of an aircraft body from which horizontal wings and a vertical wing have been decoupled, a wedge-shaped pressing member that is mounted to an upper portion of the shell to press at least one portion of a circumference of at least one of annular frames juxtaposed in a longitudinal direction of the fuselage toward a center of the fuselage, a pair of sidewall pressing members that is mounted to both sides of the shell to press the fuselage simultaneously from two directions crossing a pressing direction of the wedge-shaped pressing member at the center of the fuselage after pressing by the wedge-shaped pressing member, and a moving unit that moves the fuselage of the aircraft and the shell relative to one another.
Abstract:
Moisturized organic material is treated by communicating with a vacuum pump (44) to selectively reduce pressure within a vessel (12) below atmospheric pressure and to a vaporization point, such as at 30 to 17.8 C, for a period of time sufficient to create an internal pressure to rupture cell walls. While being subjected to vacuum below atmospheric pressure, the vessel (12) is rotated to homogenize the moisturized organic material. The organic material can be moisturized by non-potable water including moisture collected by a moisture collector (44b) in the conduit (44a) between the vessel (12) and the vacuum pump (44) and by chilled feed water acting as the seal fluid in the vacuum pump and heated while flowing through a heat exchanger (48) of the moisture collector (44b). Heat can be added by a heater (46) to raise the temperature of low ambient temperature moisturized organic material.
