    Abstract: In one aspect, a gasification system for use with low rank fuel is provided. The system includes a first gasifier positioned to receive a feed of low rank fuel, the first gasifier being configured to gasify the low rank fuel to produce hydrocarbons and fixed carbon. The system also includes a second gasifier configured to produce a syngas stream using the received fixed carbon, a cooler configured to receive and cool the syngas stream, and a first conduit coupled between the cooler and the first gasifier. The first conduit is configured to recycle at least a portion of the syngas stream to the first gasifier to facilitate heating low rank fuel within the first gasifier. The recycled syngas stream is mixed with the hydrocarbons to produce a hydrocarbon-rich syngas stream. The system also includes a second conduit coupled to the first gasifier for receiving the hydrocarbon-rich syngas stream.

    Abstract: A method includes monitoring a pressure of a gasification system after gasifier shutdown via a pressure sensor, wherein the gasification system includes a gas treatment system and a gasifier configured to output syngas to the gas treatment system during gasification. In addition, the method includes depressurizing the gasification system after gasifier shutdown by opening a flare valve to release gas from the gasifier and the gas treatment system to an atmosphere. The method also includes pressurizing the gasification system after gasifier shutdown, when the monitored pressure reaches a lower pressure threshold, by establishing multiple purge flows of inert gas into the gasification system to remove residual gas from the gasification system. The multiple purge flows are established at different times and at different locations within the gasification system relative to each other.
