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 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 fo…
