Our largest standard cryogenic oxygen plant, the POPLAR Series is a highly modular system that produces liquid oxygen, liquid nitrogen, and, as an option, liquid argon for both industrial and medical applications. This plant is the perfect representation of Nikkiso Cosmodyne’s 50 years of experience in the field. With world class energy efficiency, the POPLAR Series is second to none in performance, reliability and functionality.
Capacities range from just over 40 metric tons per day to 200 metric tons per day of total liquid product. Like the ASPEN Series, POPLAR is available with an optional high purity nitrogen gas stream. Despite its large production level, the POPLAR features a relatively compact modular design that can be shipped and installed quickly and easily.
The POPLAR plant is designed to minimize shipping and allow for rapid installation by providing the plant in seven distinct, pre-piped and pre-wired modules: cold box, turbo-expander, air chiller, heater skid and absorber vessels.
In addition, gaseous nitrogen or gaseous oxygen is also available if required for on-site or pipeline applications. The POPLAR plant employs a PLC based control system, with a user-friendly graphic interface. After start up, the plant operation is fully automated with provision for local or remote access via telephone line or the internet. The battery limits to the plant are simple; power to each of the two compressors, power to the medium voltage distribution, cooling water, and product connections. When run in maximum oxygen mode, a nitrogen gas stream is available for pipeline application or future liquefaction. Similarly, in maximum nitrogen mode, the plant can be tailored to produce oxygen gas along with other liquid products for pipeline or other on-site application. If desired, the gas streams can be fed to a Nikkiso Cosmodyne ELM series liquefier for liquefaction.
