On May 15, 2015, Air Products and Chemicals Inc. (Allentown, Pa.) successfully captured and stored its 2 millionth metric ton of carbon dioxide (CO2) in a project sponsored by the National Energy Technology Laboratory (NETL). Located at a  hydrogen-production facility in Port Arthur, Texas, the project is demonstrating an innovative gas-separation technology called vacuum swing adsorption. The technology is being used to capture more than 90 percent of the CO2 from the product streams of two commercial-scale steam methane reformers, preventing its release into the atmosphere.

In addition to demonstrating their vacuum swing adsorption technology, Air Products is also helping to verify that CO2 enhanced oil recovery (CO2-EOR) is an effective method for permanently storing CO2, a greenhouse gas. CO2-EOR allows CO2 to be stored safely and permanently  in geologic formations, while increasing oil production from fields once thought to be exhausted.

The CO2 captured from Port Arthur is being used for EOR at the West Hastings oilfield in southeast Texas. Injected CO2 is able to dissolve and displace oil residue that is trapped in rock pores. It has been estimated that the West Hastings oilfield could produce between 60 and 90 million additional barrels of oil using CO2 injection.

In total, projects sponsored by the U.S. Department of Energy (DOE) have captured and securely stored more than 10 million metric tons of CO2 to date, equivalent to taking more than 2 million cars off the road for a year. Projects such as Air Products’ are critical to paving the way for more widespread use of carbon sequestration technologies.

Air Products’ vacuum swing adsorption project is supported through the Energy Department’s Industrial Carbon Capture and Storage (ICCS) program, which is advancing the deployment of carbon-capture and -storage technologies at commercial and utility-scale. Carbon capture and storage helps to ensure that U.S. industries are powered as efficiently, sustainably, and cleanly as possible, using all of America’s abundant energy resources.
