PSA nitrogen generators are fed compressed air which goes to two vessels alternately. One vessel fed by pre-treated air produces nitrogen, and the other undergoes regeneration by depressurization, purging the adsorbed gases, and then repressurization. This cyclic process ensures a continuous supply of nitrogen. The adsorbent materials selectively capture gases like oxygen, carbon dioxide and other trace gases within the compressed air stream while allowing nitrogen to pass through.
TIGG Corporation, a manufacturer of activated carbon adsorption vessels, custom air receivers and other steel tanks and pressure vessels, substantially reduced its energy costs after implementing equipment, labor consolidation and procedural changes resulting from a compressed air energy audit. The audit was performed at TIGG's 155,000 square feet manufacturing facility in Heber Springs, Arkansas to determine the efficiency of the existing compressed air system and to set a baseline for TIGG's participation in Entergy Arkansas’ Large C&I Custom Incentive Program.
