Air prepurification for cryogenic distillation
In Air Separation Units (ASU), the first step is to remove water, carbon dioxide, nitrogen oxide and hydrocarbons using a Pressure Swing Adsorption Process (PSA). This is achieved with molecular sieves such as Arkema’s Airsiev® products.
Downstream, air is processed in a cryogenic distillation column to produce pure nitrogen (N2), oxygen (O2) and argon (Ar). The molecular sieves unit is a very critical step of the process to avoid any damage to the cryogenic section.
