摘要:
A process for the disposal of carbon dioxide in deep sea, which comprises compressing and dehumidifying gaseous carbon dioxide to be disposed of, passing the so compressed carbon dioxide gas through a cold sea water region where a temperature condition enough to liquefy the compressed carbon dioxide gas prevails via a pipe line to effect cooling of the gas by heat exchange with the cold sea water to thereby liquefy the compressed carbon dioxide gas, conducting the liquefied carbon dioxide through an extension of the pipe line to such a depth of sea water, that the specific weight of the liquefied carbon dioxide at such depth is greater than that of the ambient sea water of such depth, and then discharging out the liquefied carbon dioxide into such deep sea.

It is proposed to construct a large diameter subsea bore hole (e.g. about 10 to 50 meters in diameter) provided with a stable wall by a method which comprises drilling a number of bore holes around the circumference of a ring of large diameter, supplying to the ring bore holes material to locally stabilize the surrounding geologic formations, and forming a central bore hole, or shaft, within the perimeter of the ring by drilling and reaming or by excavation. The ring bore holes and locally stabilized geologic formations form a stable wall of large diameter for the central bore hole shaft. It is contemplated that a large diameter subsea bore hole of the type described above could be used for the safe emplacement and disposal beneath the seabed of a large waste job object such as the shielded reactor core of a decommissioned nuclear submarine, or of other waste objects containing radioactive material.

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.

An apparatus for reducing the amount of carbon dioxide released into the atmosphere by fixing and dumping carbon dioxide which is disposed in seawater or fresh water satisfying certain temperature and pressure conditions for the formation of carbon dioxide hydrate or its clathrate comprising:a) a transport pipeline equipped with a compressor;b) a carbon dioxide source connected to said transport pipeline upstream of said compressor;c) a plurality of ejector nozzles disposed at one end of the pipeline;d) a reaction housing which allows seawater or fresh water and carbon dioxide to react with each other and form the carbon dioxide hydrate or its clathrate;e) a dispersing propeller;wherein the reaction device is provided with the ejector nozzles and the dispersing propeller at the inlet portion of the device; the concentration of the carbon dioxide is supplied into the pipeline and is discharged by the compressor into the reaction housing from the ejector nozzles under pressure to form the carbon dioxide hydrate or its clathrate; the thus produced hydrate or its clathrate is dispersed by the propeller out of the reaction housing to the deep bottom of the sea.

A method for treating trash and waste tires provides a bag-like container for loading trash consisting of two "tire-nets" sandwiching a plastic layer therebetween. The tire-net is formed by a plurality of wires passing through a plurality of aligned waste tires. Trash is filled into the bag-like container via its open end to a pre-determined extent. Sea water is introduced into the container during and after trash-filling to sterilize the trash therein. The used sea water is pumped out of the container to a waste water treating apparatus to avoid pollution. After filling, the container is enveloped to form a sealed unit, and is then used to fill an area of sea to be reclaimed. The plastic layer is preferably made of acidproof and alkalineproof material to insure an effective and long-lasting sealing.

A method of disposal of waste solid material in an underwater geologic fotion on the continental margins comprises the steps of: drilling a large diameter hole into the geologic formation to a depth of several hundred feet in a single stroke operation; depositing a slug of a paste of waste material into the bottom of the hole thereby burying the slug; and permitting the geologic formation adjacent to the hole above the buried slug to fill the hole above the slug, thereby sealing the buried slug in the geologic formation. A continuous slug of waste material can be used, or the waste material can be formed into discrete charges of material.
摘要:
Method and apparatus for the disposal of solid waste material in which the refuse is transported out to sea to a disposal barge. The barge is provided with a large diameter telescoping pipe extending below the surface. The upper end of the pipe extends approximately 50 feet above the surface. The refuse is conveyed from the barge to the upper end of the pipe and discharged into the pipe. The accumulation of material in the pipe from the surface of the sea to the top of the pipe causes the material to be forced downward in the pipe until it reaches the 300 foot level below the surface. Water pressure at that level compresses virtually all of the refuse in the pipe so that it descends to the sea bottom. The end of the pipe is provided with a trap for any of the materials which will float even after being compressed at that depth.

The herein invention encompasses systems and processes required for the application of a sea freefall penetrators containing C-rich material allowing long-term C storage in deep sea sediments. The invention encompasses methods of manufacturing in the form of carbon made structure, the operational parameters such as the overall density, dimension and data obtained in field trials to successfully bury atmospheric carbon in deep-sea sediment, and the process acting in its geological storage.
