The objective of the research is to systematize and evaluate existing methodologies for optimizing compressed air supply in order to reduce operating costs and increase the overall energy efficiency of PTS. To this end, a review of specialized scientific publications over the past five years was conducted, devoted to the modeling, control and modernization of pneumatic transportation systems. The methodology is based on a comprehensive approach: theoretical foundations of two-phase flows are examined, the effectiveness of adaptive control systems (PID controllers, PLC, MPC) is compared, and the performance of modern compressor and peripheral equipment is evaluated. Based on the obtained data, a practical step-by-step framework for small and medium-sized enterprises is proposed, including an audit of the current state, digital modeling and implementation of optimization solutions. Within the study, specific recommendations are formulated regarding the selection of components and the configuration of operating modes, which allow achieving a reduction in specific energy consumption without significant capital expenditures. It is concluded that the integration of adaptive control algorithms and the precise selection of equipment constitute key factors in the pursuit of maximum energy efficiency. The information presented in this work will be of interest to engineers, production managers and researchers in the field of industrial energy efficiency.HAL open archive record: https://hal.science/hal-05855802 (hal-05855802)
