Air Products successfully demonstrated under DOE project DE-FE0007759i a 4% reduction in cost of electricity (COE) from a low-rank coal-based, integrated gasification and combined cycle (IGCC) plant with CO2 capture. This represents a 14% decrease in the cost of carbon capture compared to the NETL S3B reference caseii. However, testing to date was only conducted for one week periods of time and did not allow for prolonged stability testing on authentic syngas. This is a critical limitation for commercialization that will be addressed in our proposal. In this project, Air Products proposes to operate a two-bed mobile system at the National Carbon Capture Center (NCCC) facility. A slipstream of authentic, high-hydrogen syngas based on low-rank coal will be evaluated as the feedstock. Testing will be conducted for approximately eight weeks, thereby providing far longer adsorbent exposure data than demonstrated to date. By utilizing real-world, high- hydrogen syngas, information necessary to understand the utility of the system for methanol production will be made available. In addition, Air Products will also operate a multi-bed PSA process development unit (PDU), located at its Trexlertown, PA headquarters, to evaluate the impact of incorporating pressure equalization steps in the process cycle. This testing will be conducted utilizing a sulfur-free, synthetic syngas, and will improve the reliability of the prediction of the system’s operating performance at commercial scale. Finally, information obtained from both the two-bed PSA system operated with authentic high- hydrogen syngas and the multi-bed system operated with synthetic syngas will be combined to build a techno-economic analysis (TEA) of Sour PSA utilization for methanol production. It will also be used to update the TEA already completed for IGCC in the above-referenced DOE project. i.
