The air separation unit produces oxygen, nitrogen and argon from atmospheric air by low-temperature rectification. Air is compressed, cleaned of moisture and carbon dioxide, cooled to cryogenic temperatures and separated in rectification columns.
We designed the control system, developed the application software on the Russian Astra.Regul platform and the emergency shutdown logic on a Regul R500S controller. Interlocks and protections are in place; the purification unit sequence runs in automatic, step-by-step and manual modes.
The system has passed factory acceptance tests.
