Preface
The automation of production processes in modern industrial enterprises has further increased the importance of compressed gas systems. In particular, compressed air is widely used as one of the main energy sources in pneumatic control systems, automatic production lines, sensor and actuator mechanisms. Therefore, the design and calculation of compressed gas systems in accordance with the requirements is of strategic importance in terms of production continuity, technological reliability and energy efficiency.

1. Introduction
Compressed gas systems are an integral part of modern production facilities. Their correct calculation is not limited only to the selection of a compressor. This includes determining gas consumption, assessing compressor efficiency, calculating pressure losses, ensuring gas quality, and organizing real-time monitoring.
This methodological approach ensures stable operation of production processes, equipment reliability, and optimizing energy consumption.

2. Goals and objectives
Goal
To study the methodology for calculating the compliance of compressed gas systems used in production processes with technological requirements and evaluate their integration with automated control systems.
Main tasks
Investigating the role of compressed gas systems in production;
Calculating the gas demand of pneumatic equipment;
Estimating compressor efficiency;
Determining pressure losses;
Estimating gas quality;
Studying the application of monitoring and automated control systems.
⸻
3. The role of compressed gas systems in production
Compressed air is the main energy source of pneumatic systems and is widely used in the following areas:
Pneumatic cylinders;
Pneumatic valves;
Automatic control systems;
Conveyor lines;
Robotic production and packaging systems.
For the reliable operation of these systems, the required pressure and air flow must be ensured continuously.
⸻
4. Calculation of gas demand
The total gas consumption of the system is determined based on the sum of the air consumption of all pneumatic equipment.
Total consumption:
Q = q₁ + q₂ + q₃ + … + qₙ
Where:
Q — total gas consumption;
qₙ — gas consumption of each equipment.
In practical design, a 10–30% safety factor is applied to ensure the reliability of the system.
⸻
5. Evaluation of compressor efficiency
Compressor efficiency should fully cover the maximum gas demand of production.
Basic principle:
Compressor efficiency ≥ Total gas demand
Insufficient efficiency leads to the following problems:
pressure drop;
unstable operation of pneumatic equipment;
stoppage of automated processes;
reduced productivity.
⸻
6. Calculation of pressure losses
For normal operation of pneumatic systems, the working pressure is usually maintained in the range of 6–8 bar.
The actual working pressure is calculated by the following formula:
P_real = P_source − P_loss
The main factors affecting pressure losses:
pipeline length;
pipe diameter;
filters and dryers;
distribution network;
air leaks.
⸻
7. Compressed gas quality indicators
The quality of compressed gas directly affects the reliability of the system.
Key indicators:
humidity;
oil content;
temperature;
mechanical particles.
Correct selection of filtration and air drying systems increases the service life of pneumatic equipment and minimizes failures.
⸻
8. Monitoring and automated control
Compressed gas systems in modern industrial enterprises are monitored in real time using the following technologies:
pressure sensors;
flow meters;
PLC control systems;
SCADA monitoring platforms;
ERP integration systems.
The collected data allows you to assess the efficiency of the system and detect failures at an early stage.
⸻
9. Energy efficiency assessment
Energy consumption in compressor systems is determined by the following formula:
E = N × t
Where:
E — energy consumption (kWh);
N — compressor power (kW);
t — operating time (hours).
The following measures are recommended to increase energy efficiency:
selection of optimal operating pressure;
elimination of air leaks;
application of variable speed drive (VSD) compressors;
use of automatic control systems;
regular energy monitoring.
⸻
Conclusion
Calculation of compliance of compressed gas systems with requirements in production processes is based on determining the gas consumption of pneumatic equipment, correct selection of compressor efficiency, calculation of pressure losses, ensuring gas quality and organization of real-time monitoring.
The application of this methodology ensures the continuity of production processes, minimizes energy losses, increases equipment reliability and increases the overall production efficiency of the enterprise.
Fleetstock Academy believes that scientific calculation and digital control of compressed gas systems is one of the main conditions for increasing the technological sustainability, energy efficiency and competitiveness of modern industrial enterprises.
