Summary

Oxygen enrichment is known to improve efficiency and productivity of glass melting furnaces. Its economics, however, have always been marginal due to high cost—typically $100 per ton—of delivered liquid oxygen. With support from the Gas Research Institute (GRI), a new oxygen generator has been developed by the Xorbox Division of Greene & Kellogg, Inc. that is able to provide $40/50-per-ton oxygen. Oxygen enrichment is, therefore, now economically feasible. The design of the generator is based on an innovative single-bed vacuum assisted Pressure Swing Adsorption (PSA) oxygen generation process. Air is introduced under pressure to a packed bed of synthetic zeolite, trade-named molecular sieve. The sieve removes most of the nitrogen that makes up about 78% of the atmosphere and produces an oxygen-rich stream of up to 95% oxygen. Conventional PSA Systems have two to four beds and require expensive piping and controls. In comparison, the single-bed process developed for the project utilizes only one adsorbent bed and a surge tank. The cost of the adsorbent, piping and controls, therefore, is lower. The single-bed process, in addition, allows for the use of a very low cost blower instead of the expensive compressors that are required to operate conventional PSA systems.
