Please share your insights regarding the consumption of instrument air and compressed air in caustic soda production (without considering the differences between mechanical stirring and air stirring in the primary brine stage). We would appreciate your suggestions: how should the supply of instrument air and compressed air be arranged for a caustic soda plant with an annual production capacity of 150,000 tons? # ， ， &
The air consumption for instruments is very low; a 20-cubic-foot air compressor is sufficient to meet the requirements of facilities producing 150,000 tons of ion-exchange membrane caustic soda. Some manufacturers use two 40-cubic-foot air compressors for such facilities (one in operation and one as a backup).
The calculation of the instrument air consumption is done by first determining the air requirement for the actuator, after each type of instrument valve has been selected. Still, it is necessary to have many experienced seniors provide guidance.
