Regarding process compressed air
Thread Content
Process compressed air is mentioned in the process package – what is the difference between it and instrument compressed air? The indicators show that the dew point temperature of the process compressed air is ≤ -40°C, and that of the instrumentated compressed air is ≤ -20°C. What is process compressed air mainly used for? Please give me your advice
Compressed air is mainly used to supply instrument air to instruments; various pneumatic valves and equipment such as compressors require compressed air :)
Process compressed air, also known as plant air, is used in the manufacturing processes for various purposes such as purging. Instrument compressed air, on the other hand, is intended for use with instruments; generally, the quality requirements for instrument compressed air are higher than those for plant air
This is mainly determined by the process requirements. In some places, the required pressure and dew point of the instrument air are quite low, while other processes demand compressed air with higher specifications; this depends on the industry and the region
Process compressed air is what’s known as plant air. The dew point requirements for plant air, according to Daoli’s standards, are not extremely strict; however, your process compressed air has a dew point that is even lower than –20°C compared to that of instrument air. It’s clear that it isn’t meant solely for purging or replacing nitrogen； Do certain stages in your processing equipment require air to participate in the oxidation reaction? Or the solution needs to be aerated, and so on...
