Design a Method to Reduce the Instrument Air Dew Point

Instrument air plants produce dry air with low dew point using different adsorption processes such as PSA and TSA. This air is utilized in analyzers and control devices. In this study, the instrument air plant of South Pars Phase 1 is simulated and its performance is evaluated. Design specification of these columns is to produce dry air with dew point of -20°C. To achieve lower desired dew points of -70°C, a two layer beds is suggested and simulated. A column with two different adsorbent of Alumina and Zeoilte is simulated and its performance is evaluated.
