Compressed air is widely used as an energy carrier. The compressed air production systems are a part of the auxiliary systems of offsite facilities. It is worth noting that the production of com-pressed air is quite an energy-intensive process, so the potential for energy saving is quite large. There is increasing the efficiency of the compressed air production by developing technology solutions for air preparation in this work. The system of air drying by cooling and the source of cold are considered in this paper. The paper presents a comparison of cooling systems from steam compression and absorption refrigerating machines from the point of view of heat exchange, energy consumption for their own needs, providing cold with required parameters. The economic effect of the proposed circuit solution is given.

The absorption of heat by rocks is accompanied by an increase in the kinetic energy of molecules and atoms and is recorded by a change in rock temperature. The thermal properties of rocks characterize the ability to transfer and absorb heat and change their size when the temperature rises. The main thermal properties of rocks are thermal conductivity, heat capacity, linear thermal expansion, and thermal volumetric expansion. In this paper, the influence of temperature effects on the thermal properties of reservoirs – the coefficient of temperature conductivity, specific heat capacity, and thermal conductivity is studied using the samples of oilsaturated reservoirs from the good number 19Bp of the Upper Uplift of Sotnikovsky deposit. The dependence of the thermal properties of the core material on temperature was revealed using a number of laboratory experiments. The results of these studies contribute to improving the reliability of data on the relationship of thermal properties with other physical properties of oilsaturated reservoirs and can be used to improve the efficiency of the development of fields of superviscous oil.
