Making Liquid CO2 From A Refinery By-Product

December 21, 2016

Food-grade liquid carbon dioxide is now being produced commercially from waste carbon dioxide, heretofore an industrial by-product that was released into the atmosphere, at a Delaware City CO2 purification and liquefaction plant run by Praxair, Inc.. Back in 2015, Praxair signed a long-term agreement with Delaware City Refining to purchase their crude carbon dioxide. The 450 ton-per-day capacity plant has just started operation. In addition, Praxair is building a dry ice facility on the site that will be capable of producing 120 tons-per-day when it begins production in 2017.

Carbon capture and storage is an important strategy for reducing greenhouse gas emissions. From 2004 – 2011, global CO2 emissions from industry increased 26%.
