Project Description

In this project, Air Products and Chemicals Inc. (ACPI) will test a two-bed pressure swing adsorption (PSA) unit on a slipstream of authentic, high-hydrogen syngas based on low-rank coal at the National Carbon Capture Center (NCCC); also a multi-bed process development unit (PDU) will be operated, refining the reliability of predictions of PSA performance at commercial scale. The information obtained from the two-bed PSA unit and the PDU will be combined to build a techno-economic assessment (TEA) of Sour PSA utilization for methanol production with 90% carbon capture, as well as to update techno-economic assessments of the technology for integrated gasification and combined cycle (IGCC). The TEA shall incorporate NETL's Cost and Performance Baseline for Fossil Energy Plants and the guidelines delineated in the funding opportunity announcement. The overarching objectives of the FOA that this project was selected from are to reduce the cost of coal conversion via gasification through (1) reducing plant capital costs; (2) reducing fuel and operations costs; and (3) increasing overall plant efficiency.

Project Benefits

Air Products has developed a proprietary alternative to conventional syngas cleanup, combining a Sour Pressure Swing Adsorption (PSA) step that separates CO2 and H2S from the desired products, and a tailgas disposition block which separates the sulfur-containing compounds and purifies the CO2 to a sequestration-grade product. Specifically, Air Products will test a two-bed PSA unit on a slipstream of authentic, high-hydrogen syngas based on low-rank coal at the National Carbon Capture Center; also a multi-bed process development unit (PDU) will be operated, refining the reliability of predictions of PSA performance at commercial scale. The information obtained from the two-bed PSA unit and the PDU will be combined to build a techno-economic assessment of PSA utilization for methanol production, as well as to update techno-economic assessments of the technology for IGCC.
