A. OBJECTIVES In this project, Air Products proposes to operate a two-bed mobile pressure swing adsorption (PSA) unit at the National Carbon Capture Center (NCCC) facility utilizing a slipstream of authentic, high-hydrogen syngas generated from low-rank coal. Testing will be conducted for approximately eight weeks, therefore providing data on a far longer adsorbent exposure period than has been demonstrated to date. By utilizing high-hydrogen syngas, it will provide information necessary to further understand the utility of the system for methanol production. Air Products will also operate a multi-bed PSA process development unit (PDU), located at its Trexlertown, PA headquarters, to evaluate the incorporation of pressure equalization steps in the PSA cycle, and to improve predictions of system operation at commercial scale. This testing will be conducted utilizing a sulfur-free, synthetic syngas. Lastly, information obtained from the PSA system operated with authentic high-hydrogen syngas and the multi- bed system operated with synthetic syngas will be combined to 1) build a techno-economic assessment (TEA) of PSA utilization for methanol production; and 2) update the existing TEA for IGCC provided in DOE project DE-FE0007759. The entire project will be conducted in one budget period. The objective of Task 1 is to manage the project efficiently and cost-effectively. The objectives of Task 2 are to construct a weatherproof, mobile system containing a guard bed unit in series with a pre-existing Sour PSA unit, and to install the mobile system in a suitable location at the NCCC facility in Wilsonville, AL. In Task 3, the objective is to evaluate PSA performance with authentic syngas containing high levels of CO and H2 in prolonged testing for approximately eight weeks. The objective of Task 4 is to operate a multi-bed PSA incorporating pressure equalization steps, utilizing a sulfur-free, synthetic syngas. The objectives of Task 5 are to perform a TEA based on the experimental data to predict the economic benefits of incorporating Sour PSA for chemicals production from low-rank coal, as well as to update the TEA for the already- conducted IGCC case.
