Danbury industrial-gas maker Praxair Inc. signed a 15-year agreement with Honeywell Resins & Chemicals to recycle carbon dioxide emitted from Honeywell’s new Virginia caprolactam facility for use in freezing food, among other applications, authorities say.
Praxair didn’t disclose the value of the contract for carbon dioxide from Honeywell’s Hopewell, Va., plant due to go online in the first quarter of 2013.
The plant is expected to generate 450 tons of carbon dioxide daily as a byproduct of making caprolactam – a vital chemical feedstock in nylon production. The purified and liquefied CO2 also will be used to make beverages, officials said.
Honeywell Resins and Chemicals is one of the world’s largest producers of nylon resin and caprolactam, a critical feedstock used for nylon production. Resins and Chemicals also produces chemical intermediates and is one of the world’s largest producers of ammonium sulfate fertilizer.
