BACKGROUND
It should be understood that any discussion of the background art throughout this specification should in no way be considered as an admission that such background is prior art nor that such background art is widely known or forms part of the common general knowledge in the field.
Given the ready availability of greenhouse gases such as carbon dioxide, especially sequestered carbon dioxide (C02), it would be desirable to provide a method of sequestration of carbon dioxide which comprises exposing carbon dioxide to a mineral. The mineral may be selected from the group consisting of a mineral comprising sodium carbonate.
Governments across the world are becoming increasingly concerned to meet international obligations on minimising carbon in the atmosphere so as to meet the requirements of international treaties such as the Rio Declaration (1992) and the Kyoto Protocol. Thus, an object of the method and system of this invention may include providing a method of sequestration of carbon dioxide and associated system which provides an alternative method when compared to the prior art.
SUMMARY OF THIS INVENTION
In accordance with an embodiment of this invention, there is provided a method of sequestration of carbon dioxide comprising:
a) introducing carbon dioxide and water into at least one underground salt formation; and
b) exposing the aqueous carbon dioxide with salt in the at least one underground salt formation to form carbonates within the underground salt formation.
The carbon dioxide may be pressurised or supercritical carbon dioxide. The at least one underground salt formation may be at least one underground salt cavern. Typically, there may be two, three or four or more underground salt caverns. The at least one underground salt formation or cavern may be in communication with each other. The plurality of underground salt formations or caverns may be connected by one or more channels. In a particular embodiment, there are two or more salt caverns are connected by one or more channels wherein the walls of the salt formations or caverns are adapted to increase the surface area of the walls of the underground salt formations or channels with the carbon dioxide.
The at least one underground salt formation or caverns may be surrounded by an underground halite body. The underground halite body surrounding the underground salt formation or caverns may comprise fractured halites so as to increase the exposure of the aqueous carbon dioxide to salt. The method may be conducted in at least two underground storage caverns where the storage caverns are in communication with each other by one or more channels. The channels may be porous so as to allow for in situ sequestration of carbon dioxide in the surrounding mineral formation which may be a halite body.
The underground mineral formation may be a mineral formation which comprises solid halite and fractured halite. The fractures halite may be produced by explosions in the underground solid halite body. The underground mineral formation may also comprise minerals which comprise one or metal ions selected from the group consisting of sodium, calcium, and magnesium.
In another aspect of this invention, there is provided a system for sequestration of carbon dioxide comprising:
a) an element for introducing carbon dioxide and water into at least one underground salt formation; and
b) at least one underground salt formation for exposing the aqueous carbon dioxide with salt to allow for sequestration of carbon dioxide by formation of carbonates within the underground salt formation.
BRIEF DESCRIPTION OF THE DRAWINGS
This invention will now be described, by way of example only, with reference to the accompanying drawings; in which:
Figure 1 depicts a method of sequestration of carbon dioxide in accordance with a first embodiment of this invention.
In Figure 1, there is shown a system and method (10) for sequestration of carbon dioxide. High pressure or supercritical carbon dioxide and water is introduced via injection pipes (12) and (14) respectively to a pair of underground salt caverns (16) and (18), respectively. The underground salt caverns are preferably underground salt caverns which are in communication with each other by way of a channel (20). It will be appreciated that there may be more than one channel (20) between respective underground salt caverns (16) and (18) respectively. It will also be appreciated that there may be more than two underground salt caverns.
The underground salt caverns and the channels are surrounded by an underground mineral formation (22) which may comprise one or more elements selected from calcium, magnesium and sodium. An example of suitable underground mineral formation includes a halite body. The halite body may comprise a portion of solid halite and a portion of fractured halite. The fractured halite may be produced by explosions of the solid halite body.
In use, the compressed and high pressure carbon dioxide is fed together with water into the injection pipes (12) and (14) to from aqueous carbon dioxide in the underground salt caverns (16) and (18) respectively. The source of carbon dioxide for the underground storage cavern may be pressurised, liquid or supercritical or sequestered carbon dioxide.
The aqueous carbon dioxide is exposed to the salt in the fractured and solid halite body along one or more surfaces (24) or (26) of the channel (20). The channel (20) or the wall of the underground salt caverns (16) and (18) may be treated in any manner which increases the surface area of the halite to the carbon dioxide. This may be effected, for example, by way of jagged walls. The channels may also be porous to increase the surface area and exposure to carbon dioxide.
Further, it is observed that the aqueous carbon dioxide reacts with the salt to form carbonates, particularly sodium carbonate, sodium bicarbonate and mixtures thereof.
The advantages of this invention include the sequestered carbon dioxide is captured in the underground mineral formation as a carbonate material, particularly sodium carbonate and sodium bicarbonate. Modifications and variations such as would be apparent to those skilled in the art are understood to be well within the scope of this invention. It will be understood that this invention should not be restricted to the particular embodiments described in the preferred embodiment.
