摘要： Offshore systems and methods may be configured for oil production, offshore power generation, ammonia production, and carbon dioxide injection for EOR. For example, a method performed on an offshore facility may include: separating a produced hydrocarbon into a produced gas and a produced oil; combusting the produced gas to produce power and a flue gas; at least partially removing nitrogen from the flue gas to produce a carbon dioxide-enriched flue gas and a nitrogen-enriched flue gas; reforming a portion of the produced gas to produce a stream including hydrogen and carbon dioxide; at least partially separating the carbon dioxide from the stream to yield a carbon dioxide stream and a hydrogen stream; reacting the hydrogen stream and the nitrogen-enriched flue gas to yield ammonia; combining and compressing the carbon dioxide stream and the carbon dioxide-enriched flue gas; and injecting the compressed gas from the gas compressor into the gas reservoir.

摘要： Provided herein is process of obtaining hydrogen from a blue hydrogen production facility that meets a target carbon intensity (CIT), the process comprising: generating hydrogen from non-renewable feedstock; capturing and sequestering fossil CO2 derived from the non-renewable feedstock; and at least partially powering hydrogen production with renewable electricity, the renewable electricity being derived from biomass in which biogenic carbon produced therefrom (e.g., carbon dioxide, char and the like) is captured and sequestered; and wherein the use of the renewable electricity in the hydrogen production allows the carbon intensity of the hydrogen produced therefrom to be reduced sufficiently so that the target carbon intensity (CIT) is achieved.

摘要： The present disclosure relates to a processes and systems for producing fuels from biomass with high carbon conversion efficiency. The processes and systems described herein provide a highly efficient process for producing hydrocarbons from biomass with very low Green House Gas (GHG) emissions using a specific combination of components, process flows, and recycle streams. The processes and systems described herein provide a carbon conversion efficiency greater than 95% with little to no GHG in the flue gas due to the novel arrangement of components and utilizes renewable energy to provide energy to some components. The system reuses water and carbon dioxide produced in the process flows and recycles naphtha and tail gas streams to other units in the system for additional conversion to syngas to produce hydrocarbon-based fuels.

摘要： A process for producing syngas that uses the syngas product from an oxygen-fired reformer to provide all necessary heating duties, which eliminates the need for a fired heater. Without the flue gas stream leaving a fired heater, all of the carbon dioxide produced by the reforming process is concentrated in the high-pressure syngas stream, allowing essentially complete carbon dioxide capture.

摘要： A method and system for converting a syngas stream to a shifted syngas stream in a shift reactor comprising a first mode of operation and a second mode of operation. The first mode of operation uses heat from the shifted syngas stream to superheat steam in a heat exchanger. The second mode of operation uses the same heat exchanger to heat a partially shifted syngas stream while the shift reactor is heating up to a normal operating temperature.
