Definitions
- This invention relates to a process for storage and sequestration of carbon dioxide (C0 2 ). More particularly, this invention relates to a process for underground storage and sequestration of carbon dioxide in submerged sea areas of natural gas hydrate deposits.
- Carbon dioxide capture would be most efficiently applied to large "point sources” in order to gain economies of scale both in the capture process itself and in subsequent transportation and storage.
- sources include fossil-fuel power stations, oil refineries, petrochemical plant, cement works and iron and steel plants.
- transportation is most likely to be by pipeline in preference to batch handling, although liquefied gas tankers have been suggested as an option for a demonstration project.
- a range of storage options have been proposed, including injection into depleted oil and/or gas reservoirs, geological aquifers, deep unminable coal seams and on or below the deep ocean bed.
- FIG. 1 is a schematic diagram showing a laser imaging system employed for the purpose of verifying the concept of this invention
- Fig. 2 is a graphical representation showing conditions for methane hydrate formation as part of the conceptual verification;
- Fig.3 is a laser image showing methane hydrate embedded in sediment;
- Fig. 4 is a laser image showing methane hydrate embedded in the sediment near the sediment surface;
- Fig.5 is a laser image of the sediment after completion of a test to verify operability of this invention
- Fig. 6 is a diagram showing the gas chromatographic analysis of a gas phase sample (100 mole % C0 2 ) at the start of a test to verify operability of this invention.
- Fig. 7 is a diagram showing the gas chromatographic analysis of a gas phase sample after 68 hours (27.67 mol % of methane) of operation of a test to verify operability of this invention.
- the invention claimed herein is a method for sequestration and storage of C0 2 in which the C0 2 to be sequestered and stored is injected into a subterranean methane hydrate field whereby the methane in the methane hydrate field is displaced by the C0 2 and, in so doing, the methane is released for collection.
- the laser imaging tool comprises two primary components, a laser operation component 10 and an analytical component 11.
- the laser operation component 10 comprises an air-cooled, solid-state diode laser 13 operating with a peak power of 200W at a wavelength of 808nm with pulse energy up to 20mJ, available from Oxford Lasers Company, U.K., a high-pressure sapphire cell 12 into which a sample to be tested is introduced, a diffuser 14 intermediate laser 13, and a high-resolution digital camera 21 capable of image capture at up to 10,000 frames per second disposed on a side of sapphire cell 12 opposite laser 13.
- the analytical component 11 comprises a high resolution digital camera control unit 19 operably connected to camera 21 and laser control unit 16 operably connected to laser 13. Also included within the analytical component 11 are a PC monitor 17 operably connected to a computer processing unit (CPU) 18 to monitor and store data, a video monitor 20 operably connected to the high resolution digital camera control unit 19 and a video cassette recorder 22 to record the imaging events in the sapphire cell 12.
- the laser imaging system is capable of operating at high pressures (1500 psia) and low temperatures (- 40°C to 100°C).
- the high-pressure sapphire cell was packed with wet (water) sand sediment of about 30% porosity, similar to that of the Gulf of Mexico sediment, connected into the laser imaging system and charged with pure methane to a pressure of 700 psia.
- a NESLAB chiller available from Thermo NESLAB, Portsmouth, NH, was used to cool and heat the cell at programmed rates (0.1 ° C per minute). The temperature of the cell initially was reduced from about 25°C to about 2°C.
- the pressure and temperature in the sapphire cell were measured simultaneously using a digital pressure sensor and thermocouple, respectively. Laser pulses from the laser illuminated the sapphire cell.
- the laser beam acts as a very short- duration strobe lamp for the high-speed digital camera, freezing the rapid action of hydrate formation and dissociation in the sediments in the sapphire cell.
- the high-resolution digital camera recorded the imaging events.
- a computer controlled the system while also collecting and processing pressure, temperature, time, and image data. Temperature and pressure measurements were tracked in real time.
- Methane and C0 2 content were analyzed using a Hewlett Packard (HP) gas chromatograph three times: at the start, after 68 hours, and after 92 hours. The data were collected and analyzed. The results of these tests confirm that the methane gas released from the hydrate field was displaced by CO 2 .
- methane hydrate was formed, based upon the use of a calculated 0.0263 moles of methane, in the sediment at 3.5°C during the cooling run. The system was then cooled to about 2°C and held at that temperature for 2 hours.
- Fig. 6 shows the gas chromatographic analysis of the sample from the gas phase (a single peak representative of 100 mole % C0 2 ) at the start of the test.
- Fig.7 shows the gas chromatographic analysis of the sample from the gas phase after 68 hours (two peaks, one of which is representative of 27.67 mole % of methane). After the first sampling, thermodynamic material balance calculations indicated that 0.0235 moles (89.35 %) of methane were released out of the total 0.0263 moles of methane utilized in the hydrate sediment. At the end of 92 hours, gas chromatographic analysis of the gas-phase sample confirmed a methane content of 17.97 mol %.
- Implementation of the method of this invention may be carried out in a variety of manners.
- One of the simplest implementations involves the use of concentric conduits in which the carbon dioxide is injected through the inner conduit into the methane hydrate field and displaced methane is collected in the annular region between the inner and outer concentric conduits for transmission away from the resulting carbon dioxide hydrate field.
