  • Method for the fixation of carbon dioxide
    Patent number: 5364611
    Abstract: 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 de

  • Method for the fixation of carbon dioxide, apparatus for fixing and disposing carbon dioxide, and apparatus for the treatment of carbon dioxide
    Patent number: 5304356
    Abstract: 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
