The invention relates to the storage of contaminated material under a water layer, in particular the storage of bottom ash. The invention provides for this purpose a method for storing a contaminated material under a water layer, comprising the processing steps of supplying the contaminated material, supplying ground material, mixing the contaminated material with the ground material and arranging the mixture of contaminated material and ground material in or under a retention layer situated under a water layer, and wherein the mixture is not in contact with the water layer, and the retention layer comprises ground material. The invention also provides an installation for storing contaminated material and a composition comprising the contaminated material.

A ground cover in the form of a flexible substrate defining a plurality of compactly arranged extractable sections. The installation method involves passing the substrate material from a feed roll to an extraction site on a mobile installation apparatus. A plurality of drive pins are aligned with the substrate and, as the drive pins advance, the sections are extracted and driven into the soil. Various drive pins arrangements are shown and the drive pins may reciprocate along with a rotational or impacting stroke to penetrate the soil while implanting the substrate sections.

Industrial process for the treatment of RSW without selecting, that after being milled are added with sanitizing solutions, binders and hardeners which chemically immobilize them avoid the production of percolating liquids, leaching of heavy metals and generation of greenhouse gases. The resulting material—a grey, warm and malleable paste—forges, allowing diverse uses; it can be directly buried in the ground without special protections; can be used as construction material for urban furniture or architectural structures; or can be anchored in the ocean, building habitats of ocean ecosystems, if it is properly packaged in waterproof material.

A new system for underwater waste disposal is disclosed, consisting of a high-speed, hardened penetrator, optional rocket motor (or other compact propulsion device) and alternative mechanisms for eliminating water drag by surrounding the projectile with a gas layer.
摘要:
Disclosed is a system for sequestering carbon dioxide by combining sub-cooled carbon dioxide gas phase and liquid water (fresh or salt) in a reactor to form carbon dioxide clathrates in a continuous process at pressures from 3 to 20 atmospheres. The seawater feed for the clathrate reactor is pumped to the surface from a depth of approximately 1000 meters. A slip stream of the reactor feed water is used to pre-cool the carbon dioxide gases. The pre-cooled gaseous, or liquid carbon dioxide and the reactor surfaces are then sub-cooled by refrigeration to temperatures of -40.degree. C. to 0.degree. C., which is typically only 5.degree. to 45.degree. C. below ambient sea water temperatures at depths of 1000 meters. Forming clathrates in this manner is considerably less energy-intensive than CO.sub.2 compression and liquefaction at high pressures.

Disclosed are a method for the fixation of carbon dioxide which is characterized by the steps of bringing carbon dioxide and seawater or fresh water into contact with each other at a temperature and a pressure required for the formation of carbon dioxide hydrate, and sinking it in the seawater or fresh water satisfying certain conditions for the stability of carbon dioxide hydrate; a method for the fixation of carbon dioxide which uses a pressurized pipeline for producing and cooling the hydrate and releases the product hydrate at a position in the sea where the hydrate can remain stable; an apparatus for fixing and dumping carbon dioxide which is disposed in seawater or fresh water satisfying certain pressure and temperature conditions for the formation of carbon dioxide hydrate and which comprises a container for producing carbon dioxide hydrate, and a discharge means for discharging the hydrate produced out of the container; and an apparatus for the treatment of carbon dioxide which comprises a reaction device disposed on a deep ocean floor, a pipeline for sending concentrated carbon dioxide to the reaction device, an ejector type nozzle at an end of the pipeline, and a means for dispersing carbon dioxide hydrate produced in the reaction device over the deep ocean floor.
摘要:
Carbon dioxide gas collected from combustion exhaust gas or the like is transported in a liquefied gas state on the sea by means of ships up to a marine float installation provided with a throw-in pipe reaching to the deep sea, and then the liquefied carbon dioxide is thrown into the deep sea through the throw-in pipe.
摘要:
A method of disposal of waste material on subaqueous ground is disclosed, and comprises transporting the material to a location above a selected site for disposal, conveying the material in a vessel to a level at, or close to, the subaqueous ground, and depositing the material onto the subaqueous ground. The vessel travels under free-fall conditions for part of its descent. Also provided is a vessel which comprises a generally cylindrical body comprising a containment area having an opening at its upper end for receiving material which is to be transported by the vessel, and having at its lower end means for permitting egress of the material. The vessel is provided, at a position intermediate its upper end and its center of mass, with at least two [wing-like] wing members at diametrally opposed positions; and is also provided with means for pivoting the [wing-like] wing members between a first position in which they lie substantially flat against the exterior of the vessel and a second position in which they extend outwardly from the body of the vessel. In the second position, they present an increased surface area to the surrounding water and provide thereby a decelerating effect on the motion of the vessel when the vessel is moving downwardly within the body of water. A marine system for subaqueous waste disposal is also disclosed, which comprises a ship and a vessel generally as described above.
摘要:
This invention relates to a method of treatment and disposal of drilling waste, contaminated sediments and residual waste including the steps of providing drilling waste, contaminated sediments, residual waste or other disposable material, grinding or crushing the material, mixing the material with at least one binder, using material exhibiting a maximum particle size of less than 5 mm; transferring the mixture to a disposal device placed in a benthic zone and allowing the mixture to cure in the disposal device. A disposal facility formed by the method of this invention is described.
