Nikkiso CE&IG Group (Nikkiso CE&IG Group), a subsidiary of Nikkiso Co., Ltd (Japan), is pleased to announce it recently commissioned its TGNO-1000 gaseous oxygen and nitrogen plant. The new plant targets float glass manufacturing and was sold to an industrial gases company.
The Nikkiso Cosmodyne TGNO is a cryogenic oxygen and nitrogen generator designed to produce three gaseous product streams: medium and high-pressure nitrogen gas and oxygen gas. The high-pressure nitrogen comes directly off the nitrogen column at approximately 8.5 bar(g). The medium pressure nitrogen stream comes from the oxygen column overhead and is boosted by a waste stream expander to approximately 2.3 bar(g). The gaseous oxygen comes directly off the oxygen column which runs at an elevated pressure of 2.3 bar(g). All this is accomplished at a low specific power of 0.27 KW/Nm3.
The TGNO-1000 was configured with mostly preexisting components to meet the developmental needs of this multi-product plant. This allowed them to meet the stringent goals of their industrial gas customer, who is selling the molecules to the float glass customer. The plant also operates without an attendant, so can handle fluctuations in product demand without human intervention.
The prefabricated TGNO is delivered in pre-piped, pre-wired, easy-to-install modular sections. The chiller, adsorber beds, and switching valves and turboexpanders are mounted in a single skid, minimizing field work. The control room module houses the motor control center and required analyzers.
“This is Cosmodyne’s most recent effort to supply cryogenic systems and plants which allows our industrial gas customers to develop their market and compete effectively, according to George Pappagelis, President of Process Systems. “The TGNO-1000 was a collaborative effort among our operations in the US and India.”
Nikkiso has extensive experience with liquid merchant plants as well as on-site gas plants like the TGNO-1000.
