Built to the highest standards of reliability and efficiency, the ASPEN is a medium-sized cryogenic air separation plant. The Aspen Series is designed to produce liquid nitrogen, oxygen and, as an option, liquid argon. Plant capacities range from 15 to 35 metric tons per day of combined liquid products with an optional high purity nitrogen gas stream for future liquefaction or on-site pipeline. This air separation unit also features the option to operate in maximum oxygen mode, in which gaseous nitrogen can be created for other on-site nitrogen needs. The Aspen Series features Nikkiso Cosmodyne’s trademark modularity. Under normal conditions the ASPEN Series can be installed and commissioned within 30 days of arrival the site.
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. The plant system is self-contained and can be completely installed outdoors. The plants require a source of cooling water, power supply and a simple foundation.
Over 35 ASPEN plants have been deployed producing liquid oxygen, nitrogen and argon for medical, industrial, oil field and military applications in some of the most remote regions of the world.
