Gas Recovery

The TGN series plants produce high gaseous nitrogen by cryogenic distillation of atmospheric air. In addition, they also produce a small amount of liquid nitrogen to store for peaking or back-up purposes. The TGN series plants are efficient, reliable, and compact.

The TGN series plant utilizes a waste gas expansion cycle using a Turboexpander to produce gaseous and liquid nitrogen. The layout is configured to provide maximum efficiency and ease of maintenance. The plant consists of three modules, an Air Compressor Module (ACM) that provides process air, a Warm Equipment Module (WEM) that purifies compressed air and a Cold Box Module (CBM) that houses the distillation equipment. These modules are pre-wired and pre-piped for ease of installation.
