EXAMPLE OF COMPRESSED AIR RECEIVER PLANT
In compressed air production and distribution systems, tanks are used in production plants for the following functions:
• to store compressed air in order to useit when needed
• to ensure network air flow and constant pressure by limiting interventions to adjust the flow;
• to favour the separation of condensation through the release of the flow coming from the compressor in the bottom of the tank and connecting delivery in the upper.
Furthermore, the tanks are located near uses characterised by highly
variable air requirements in order to limit pressure fluctuations along the
distribution lines.
Optimum tank volume in a production system depends on the type of
compressor, environmental conditions of operation and type of use.
In systems characterised by max operating pressure of 10 bar and flow
rates from 1 to 100 Nm3/min, tank capacity is calculated, as a first
approximation, with the following relationship:

V= 0.2 to 0.6 Q
V = theoretical volume of the tank in m3
Q = intake flow rate from the compressor in m3/min
0.2 = coefficient for large plants
0.6 = coefficient for small plants
