Phillips 66, with the assistance of Worley Group Inc., is performing an initial design of a commercial-scale, advanced carbon capture and storage (CCS) system that separates and stores approximately 190,000 tonnes per year net carbon dioxide (CO2) with 90%+ carbon capture efficiency from an existing steam methane reforming (SMR) plant at the Phillips 66 Rodeo Refinery. The project goal is to analyze the technical results of three different carbon capture configurations and then select the one with the smallest predicted impact to the average levelized cost of hydrogen and produce an advanced engineering design for a commercial-scale unit based on the selected configuration.
