The expediency of using a variable frequency drive for pumping units was repeatedly proved both from the point of view of the economic component and the technological one. However, the construction of automatic control systems for the operating parameters of pumping stations is mainly based on maintaining the pressure setpoint and does not include monitoring the efficiency of the aggregates working in the group and, the more so, its regulation. In this paper, an algorithm is developed for the energy efficient management of centrifugal pump units, which allows not only maintaining the pressure setpoint, but also optimizing their efficiency.

In the article analyzes the formation of areas of atmosphere pollution which caused by the compressor stations of main gas pipelines. The main dangerous factors in the zone of influence of CS, which have affect on the natural environment, is the chemical pollution of atmosphere due to emissions of harmful substances by technological equipment CS and noisiness, the source of which are gas pumping units of different types. In the atmospheric pollution, there are 3 zones: 1) zone of "undiluted" concentrations; 2)transitional zone; 3) dispersed zones. Essential processes of migration of air pollution are convectivetransfer, dispersion and molecular diffusion.Also, in the article are given the methods of calculating of the concentrations of harmful substances and estimation of the levels of air pollution in the area of the compressor station location. The main directions of reduction of the influence of CS on the environment are proposed, in particular: replacement of obsolete gas-pumping units with new ones; improvement of technological equipment; optimization of parameters of operation of gas turbine plants (GTU); the transfer of separate workshops (or CS as a whole) to electric power; reduction of ecological load on gas-pumping units (GPA); increase in the height of the smoke pipes; using secondary energy resources in the implementation of energy saving equipment and systems, etc.

The current state of transit of natural gas through the Ukrainian gas transmission system (GTS) is estimated in the paper. The prerequisites for further reduction of the GTS load in the coming years are considered, in particular in the direction of Europe through the gas measuring station "Orlivka" (south direction), taking into account the construction of alternative bypass gas pipelines. On the basis of the review of literature sources on the problem of efficient operation of gas pipelines under conditions of underloading, a method for determining the capacity and energy consumption of the gas pipeline for a given combination of working gas pumping units (GPU) was developed. The Ananyev-Tiraspol-Izmail gas pipeline at Tarutino-Orlivka section was selected as the object of research. The methodology includes the calculation of the physical properties of gas by its composition, the calculation of gas compression, the calculation of the linear part, the gas flow to the compressor station's own needs, and the calculation of the total power of the gas-pumping units under the specified technological limitations. With the help of the original software developed in the MATLAB programming language, cyclical multivariate calculations of the capacity and energy consumption of the gas pipeline were carried out and the operating modes of the compressor shop were optimized in the load range from 23 ... 60 million m3/day. Optimization criterion is the minimum total capacity of the GPU. Variable parameters at the same time are the speeds of the superchargers, different combination of working GPU, load factor. According to the results of the optimization graphical dependences were constructed: the optimum frequency of the rotor of the supercharger on the performance of the pipeline; changes in power and pressure depending on the performance of the pipeline when operating a different combination of superchargers. Recommendations have been developed to minimize fuel gas costs at the compressor station.

The pumping unit is the main pumping equipment in the oil field. However, there widely exist such defects as low pumping efficiency, high energy consumption, much time and great efforts consumption in stroke adjustment etc. in the current pumping unit, resulting in serious waste of energy. Some energy-saving technologies in pumping units have been developed, but the effects are not quite good. Aiming at this situation, this paper introduces a new type of motor control theory - Direct Torque Control. By controlling the stator voltage, the technology achieves the direct control of the motor torque. Meanwhile, with the combination of the motor running condition of pumping units, study of energy-saving control based on DTC technology is carried out. It turns out that the energy-saving effect is significant according to the application and test results of the energy-saving control device in the oil field. Therefore, the control device can bring certain economic benefits and have the value of popularization and application.

For the transportation of natural gas through pipelines, gas pumping units (GPU) are installed at numerous compressor stations (CS), the energy carrier for which, in most cases, is transported natural gas. 0.5 ... 1.5 % of the volume of transported gas is consumed (burned) by the pumping unit drive. The situation with the replacement of existing equipment with modern equipment is associated with significant investments, on the one hand, and the uncertainty with the transit of Russian natural gas through gas transmission systems of Ukraine in the near future. More promising is the way to increase the efficiency of the GPU cycle through the use of circuits with preliminary cooling of the compressed gas. The aim of this research is studying the prospects for the application of technology for pre-cooling technological natural gas before compression in a gas pumping unit based on heat-using absorption refrigeration machines. To analyze the effect of pre-cooling of technological natural gas on the compressor stations of main gas pipelines, gas pumping units – GTK-10I were selected. The calculation of GPU power consumption and fuel gas consumption at various temperatures of the process gas at the inlet to the supercharger was performed. The calculation of the operating parameters of the gas pumping unit is performed and the energy and financial prospects of the technology for cooling the process gas before compression in the GPU CS are shown. For the current economic situation (July 2019) in the Ukrainian gas market, the daily decrease in operating costs in standard gas pipelines with a decrease in gas temperature before compression in the gas pumping unit by 20 K ranges from 1800 USD to 3360 USD. A scheme of a recycling plant based on absorption water-ammonia refrigeration machine (AWRM) is proposed, which in the range of initial data allows to reduce the temperature of technological natural gas before compression by 11 ... 13 ° C.
