    • A method for in situ heating of a subsurface formation is provided. The method includes receiving hydrocarbon fluids produced from the subsurface formation as a result of heating. The method also includes processing the produced fluids to generate a hydrocarbon stream. A portion of the hydrocarbon stream is then delivered to a combustor along with an oxygen-containing stream as a combustion mixture. A diluent gas stream may also be provided for cooling. The mixture is then combusted to generate electricity, and to release an exhaust stream comprising carbon dioxide. The method also includes using at least a portion of the exhaust gas stream generated from the combustion for injection or for sequestration, thereby minimizing atmospheric release. In addition, at least a portion of the electrical power is delivered to a plurality of electrically resistive heating elements to deliver heat to the subsurface formation. A low emission power generation system is also provided.
    • 提供了地下地层加热的方法。 该方法包括接收由地下地层由加热产生的烃流体。 该方法还包括处理所产生的流体以产生烃流。 然后将一部分烃流与含氧流一起作为燃烧混合物输送到燃烧器。 还可以提供稀释气体流以进行冷却。 然后将混合物燃烧以发电,并释放包含二氧化碳的废气流。 该方法还包括使用从燃烧产生的排气流的至少一部分用于注入或隔离,由此最小化大气释放。 此外,电力的至少一部分被输送到多个电阻加热元件以将热传递到地下地层。 还提供了低排放发电系统。
