Processes, systems, and apparatus are provided for producing a compressed process gas comprising light olefin such as ethylene. The process utilizes a pyrolysis reactor to produce the process gas. A power generator utilizes a turbine operated based on an Allam cycle to produce shaft power for operating one or more compressors involved in processing of the process gas while producing a reduced or minimized amount of CO.sub.2 that is released as a low-pressure gas phase product. Examples of using the shaft power for processing of the process gas can include compressing the process gas a process gas compressor powered by the produced shaft power and cooling the process gas using a refrigeration compressor powered by the produced shaft power.

Systems and methods to separate water and remove solids from a pre-treated and unfiltered renewable feedstock at or separate from a refinery. Such systems and methods may be used to provide a reduced-contaminant and reduced-solid renewable feedstock for further refining.

Methods and apparatus for processing hydrocarbon and other feedstocks that contain lighter volatile component(s) along with heavier volatile or non-volatile component(s) and/or contaminant(s). The principal benefit being that a feedstock can be processed and separated into its distinct volatile components down to elemental and/or molecular levels, including the ability to handle the heaviest tars and bitumen within the system. This effectively provides onsite value add to the feedstock resource (minus the waste streams such as water, sulfur, or sand; which may have value as isolated components in their own right). The system is robust and can include innovative hardware, methods, and/or software. The system can isolate water, chemical, various hydrocarbon, and particle contaminants of arbitrary concentrations and sizes. These factors provide for significant increases in processing efficiencies and capabilities in the fields of refining and environmental recovery. In a variety of operating scenarios, near-zero emissions can be achieved while processing.
