  • the subsea base 2 is a minimal structure that protects the compressors 3 housed within.
  • the compressors 3 provide further pressure to the captured carbon dioxide from the pipeline 1. Power to the compressors 3 is provided by the diesel generators 5 housed within the taut moored structure 4. Power cables 6 lead from the diesel generators 5 to the compressors 3 (and to the pump 7).

  • the buoyant structure 4 consists of two tubular sections, one being a larger diameter storage chamber. Conical sections are used at the intersections of the tubulars and at the bottom of the structure, in order to reduce wave forces.
  • the larger diameter chamber is used to store power-generating equipment needed for the control, monitoring and power systems. This chamber is located below the water surface at a level designed to avoid large forces from wave action.
  • the upper surface piercing tubular section is small enough to minimise wave forces but large enough to allow access for maintenance.
  • the lower conical section is small enough to minimise wave forces, but large enough to allow storage of a quantity of fuel or ballast material.
  • the quantity of ballast material stored can be adjusted to suit localised wave conditions in order to stabilise the buoyant structure 4 motions.
  • the size of the tubular sections is designed to provide adequate buoyancy to maintain tension in the flexible connectors (providing the taut mooring) and dynamic stability during adverse weather conditions. Thus the structure 4 can be adjusted to suit different locations with differing wave climates.

  • the structure 11 can be formed using multiple chambers if desired and can be self buoyant for tow out purposes. It can be fixed to the seabed using pin piles, suction piles, or epoxy grout.
  • the power generators 13, the electrolysis equipment 14, and the methanol production equipment 15 are housed within the offshore structure 11.
  • the wind turbine 12 supplies power to the power generators 13 which provide power for the electrolysis equipment 14, methanol production equipment 15, and all pipeline transfer pumps (not shown).
  • An alternative back-up power supply can also be provided.
  • the electrolysis equipment 14 produces oxygen which is piped back to the power plant in the pipeline 17. Also produced is hydrogen which is piped into the methanol equipment 15 using pipeline 19.
  • Carbon dioxide from the power plant is piped into the methanol equipment 15 using pipeline 1.
  • the hydrogen and carbon dioxide are combined in the methanol production equipment 15 to produce the methanol which is then piped through pipeline 16 for storage or other use. Any excess carbon dioxide is transferred for storage into a depleted oil field using pipeline

Abstract

La présente invention concerne un moyen de capture du carbone en mer utilisant des structures en mer minimales. Ce moyen comporte un pipeline (1) fournissant le dioxyde de carbone séquestré, et une source de commande ou motrice (5) située dans une structure en mer minimale (4) reliée à un pipeline pourvu d'un accès à une formation géologique convenant au stockage de dioxyde de carbone. La formation géologique peut être un champ pétrolifère épuisé, une veine de houille, ou une couche rocheuse. Des compresseurs (3) placés en mer peuvent être utilisés pour pressuriser le dioxyde de carbone. La structure en mer minimale (4), qui peut être fixe ou flottante, peut être alimentée en énergie par des groupes diésel (5) ou une éolienne. L'invention peut également intégrer une récupération assistée des hydrocarbures ou "EOR" (Enhanced Oil Recovery), ou une récupération du méthane de houille ou "CBM" (Coal Bed Methane). On a également la possibilité de produire du méthanol en utilisant le dioxyde de carbone séquestré ainsi que de l'hydrogène produit par électrolyse.
