Abstract: Systems and methods are provided for integrating a fluidized coking operation, a reverse osmosis operation, a coke gasification operation and/or processes for production of compounds from the synthesis gas generated during the coke gasification. Conventional FLEXICOKING™ processes may produce carbon dioxide emissions and low Joule Flexigas, as well as waste water containing metals and poor quality coke containing metals, which may be expensive to process, or may require sending to other facilities for further processing. The systems and methods described herein address these issues in an advantageous and economical manner, with improved carbon capture, waste upgrade and chemicals production, while providing high value ash (e.g., for recovery of metals such as vanadium, nickel, sodium, iron, and mixtures thereof) and upgraded coke streams.
