Danbury/USA – Praxair also entered into a long-term contract with Libbey to deliver oxygen to its glass melting facility in the Netherlands through a non-cryogenic, vacuum pressure swing adsorption (VPSA) system. Both the TCR system and the 60 ton-per-day VPSA oxygen on-site supply system are scheduled to start up in 2017.

Through Praxair’s proprietary Optimelt TCR system, incoming natural gas is heated and reacts with a portion of the flue gas to produce a hot syngas fuel that recovers the waste heat stored in regenerators for more efficient combustion in the furnace. The system to be installed at Libbey will be designed to reduce natural gas consumption and flue gas carbon dioxide emissions by approximately 20 %.

“Our company develops technologies aimed at our mission of making our planet more productive,” said Todd Skare, chief technology officer at Praxair. “The combination of Praxair’s technology and VPSA oxygen supply system enables productivity gains in operating cost and specific energy, as well as emissions reductions, all of which help achieve Libbey's sustainability goals.”

“Libbey’s decision is part of the company’s strategy to improve energy efficiency and reduce emissions in glass production,” said Terry Hartman, vice president of engineering at Libbey.
