Abstract
A method of operating a hydrocarbon production system. The hydrocarbon production system including a gas turbine engine configured to combust hydrocarbon gas produced at the hydrocarbon production system and to provide power for the hydrocarbon production system as a result of the combustion. The method includes combusting produced hydrocarbon gas in the gas turbine engine, capturing carbon dioxide exhausted from the gas turbine engine as a result of the combustion of the hydrocarbon gas, storing the captured carbon dioxide at the hydrocarbon production system in a first set of storage pipes, and transporting the stored carbon dioxide away from the hydrocarbon production system for permanent storage.
Claims22
A method of operating a hydrocarbon production system, the hydrocarbon production system comprising a gas turbine engine configured to combust hydrocarbon gas produced at the hydrocarbon production system and to provide power for the hydrocarbon production system as a result of the combustion, the method comprising:
- combusting produced hydrocarbon gas in the gas turbine engine;
- capturing carbon dioxide exhausted from the gas turbine engine as a result of the combustion of the hydrocarbon gas;
- storing captured carbon dioxide as liquid at ambient temperature at the hydrocarbon production system in a first set of storage pipes;
- and
- transporting stored carbon dioxide away from the hydrocarbon production system for permanent storage.
A hydrocarbon production system, the hydrocarbon production system comprising:
- a gas turbine engine configured to combust hydrocarbon gas produced at the hydrocarbon production system and to provide power for the hydrocarbon production system as a result of the combustion;
- means for capturing carbon dioxide exhausted from the gas turbine engine as a result of the combustion of the hydrocarbon gas;
- a first set of storage pipes for storing captured carbon dioxide at the hydrocarbon production system, wherein the first set of storage pipes are configured to store the captured carbon dioxide as liquid at ambient temperature;
- and
- means for offloading stored carbon dioxide to a transportation vehicle configured for transporting the stored carbon dioxide away from the hydrocarbon production system for permanent storage.
A method of retrofitting an existing hydrocarbon production system, the existing hydrocarbon production system comprising a gas turbine engine configured to combust hydrocarbon gas produced at the hydrocarbon production system and to provide power for the hydrocarbon production system as a result of the combustion, the method comprises:
- installing means for capturing carbon dioxide exhausted from the gas turbine engine as a result of the combustion of the hydrocarbon gas;
- installing a first set of storage pipes for storing captured carbon dioxide at the hydrocarbon production system, wherein the first set of storage pipes are configured to store the captured carbon dioxide as liquid at ambient temperature;
- and
- installing means for offloading stored carbon dioxide to a transportation vehicle configured for transporting the stored carbon dioxide away from the hydrocarbon production system for permanent storage.
