The ASPEN plant is a medium sized air separation plant designed to produce liquid nitrogen, oxygen and, as an option, liquid argon by cryogenic distillation of atmospheric air.
In addition, when operating in maximum oxygen mode, gaseous nitrogen is also available, if required, when there is a pipeline or other on-site nitrogen requirement or to liquefy for additional liquid nitrogen capacity.
The ASPEN plant is designed to minimize shipping and allow for rapid installation by providing the plant in four distinct modules: the main air compressor, the air treatment module, the recycle compressor, and the cold box. Capacities range from 15 to 35 metric tons per day.
