Recovery Act: Demonstration of CO2 Capture and Sequestration for Steam Methane Reforming Process Gas Used for Large-Scale Hydrogen Production


Project No: FE0002381


Project Description

The DOE selected Air Products and Chemicals, Inc. (Air Products) to receive ICCS program funding through the American Recovery and Reinvestment Act (ARRA) of 2009, for its project entitled "Demonstration of CO2 Capture and Sequestration of Steam Methane Reforming Process Gas Used for Large-Scale Hydrogen Production". For this project, Air Products will demonstrate a state-of-the-art system to concentrate CO2 from two steam methane reformer (SMR) hydrogen production plants located in Port Arthur, Texas.

Air Products is retrofitting its two Port Arthur SMRs with a vacuum swing adsorption (VSA) system to separate the CO2 from the process gas stream, followed by compression and drying processes. This process will concentrate the initial stream containing from 10-20 percent CO2 to greater than 97 percent CO2 purity.

The compressed CO2 will then be delivered to the Denbury pipeline for transport to Texas EOR projects in the West Hastings Field where a monitoring, verification and accounting (MVA) program will ensure the injected CO2 remains in the underground geologic formation. The technology will remove more than 90 percent of the CO2 from the process gas stream used in a world-class scale hydrogen production facility with negligible impact on the efficiency of hydrogen production.

Project activities already completed include engineering and design. All air permits have been secured and construction is in progress. Commissioning, startup, and the operation of all components of the project are scheduled to occur by February, 2013. The MVA program to monitor the injected CO2 is being designed and will be implemented once CO2 capture begins.
