The investigation of vibroacoustic characteristic of gas-pumping units of GTK-10-4 type. Power units improvement, as a rule, results in the decrease of units steel intensity and under conditions of the increase of airgas flows and facilities developed it causes a growth of vibroacoustic activity of plants elements. Taking into account this factor, it is necessary to develop measures to reduce noise and vibrations in sources of their origin at the design elaboration both at the stage of design, and at the stage of reengineering. With this purpose there are carried out the investigations of noise and vibration characteristics of a gaspumping unit of GTK-10-4 type equipped with a sta-tionary gas-turbine unit with a capacity of 10 MWt and a natural gas supercharger of 520-12-1 type manufactured by NZL. The noise and vibration sources of impeller ma-chines are studied, their vibroacoustic characteristics are analyzed, and the methods to reduce vibroacoustic activity of gas-pumping units of such a type operating at compressor stations of trunk pipelines are offered.

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.

A review of regenerative gas turbines operating at natural gas pipeline compressor stations across the Russia has been performed. Main performance characteristics, first of all, the power and efficiency of the recuperated gas turbines, many of those have been used up a design service life, can be recovered. Since a large negative effect on the performances is contributed by defective plate-type regenerators, their change seems to be essential when updating gas-pumping units. A tubular regenerator is developed and incorporated into the gas turbines for driving natural gas blowers. The regenerator being installed in place of the plate-type heat exchanger joints a rather simple fabrication process and high durability. Its design features are presented and discussed. Ways to enhance efficiency and decrease the weight of the regenerator are considered.

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.

Regenerative Cycle

One of the urgent tasks of further developing natural gas transportation systems is the need to increase fuel efficiency and to improve environmental performance of the gas turbine units (GTU) that are used to drive superchargers of gas pumping units. Outdated GTUs with low efficiency are being replaced by units of a new generation, including those of the regenerative cycle. However, this requires significant capital expenditures, thus, the possibilities of upgrading the existing units are also being investigated. A significant proportion of the energy generated by the gas combusted in driven GTUs is lost in the form of heat of the exhaust combustion products. These gases have a temperature not lower than 670 K. To utilize the heat of the exhaust combustion products, it is proposed to compliment the main GTU by an air turbine heat recovery unit (ATU) that is simple in design and inexpensive in production. This well-known idea has not yet been realized in practice, thus there are no recommendations on the use of a GTU-ATU as a drive for natural gas superchargers. It is shown that to ensure the possibility of upgrading drive gas turbines at a minimum cost, it is advisable to use an ATU that is kinematically independent of the GTU. The ATU’s power is used to cover the own needs of the compressor station and other purposes. The calculations show that under equal conditions, the combined GTU-ATU is inferior in efficiency to the GTU of the regenerative cycle. However, it provides a much smoother flow of the efficiency parameter depending on the operation mode, which is important for gas pumping units. The potential of using the ATU for the modernization of drive GTUs is estimated. It is noted that in addition to generating additional power, the use of ATU’s can decrease the flue gas temperature and the mass concentration of harmful emissions.
