Cold Box Air Separation Unit

Air separation units (ASUs) extract pure gases from air by cooling it to a liquefied state and selectively distilling them using different boiling points. All cold processing equipment is housed in an insulated cold box, which contains cryogenic heat exchangers, distillation columns, and associated valve and piping systems.

Tight control integration between the heat exchangers and separation columns is critical to ensure efficient operation during cryogenic separations. The ASU operates a refrigeration cycle that uses the Joule-Thomson effect to achieve ultra-low distillation temperatures. However, cooling and separating high-purity gases requires a significant amount of energy to keep the refrigeration cycle effective.

NEWTEK's advanced distillation solutions are designed to increase column throughput while significantly reducing energy consumption, thereby reducing overall operating costs. With NEWTEK's process automation and control technologies, you can get early warning of failures before they occur and minimize energy consumption per unit of feed. In addition, the real-time feed composition and quality data we provide will provide unique insights into your process performance, helping to reduce product quality fluctuations and rejects.

NEWTEK's asset management and machinery health monitoring solutions enable you to proactively manage smart field devices and critical process equipment to improve plant reliability.
