Shologon V. Development of measures of effectiveness increase of gas refrigerators exploitation at the compressor stations

The aim of the dissertation is to solve such main problems as analytical research of the thermal gas dynamic processes in complex systems, definition of regularities of gas flow distribution taking into consideration variable geometric characteristics and character of hydraulic resistance, establishment of characteristic correlation between the parameters of neoisothermal gas flow in gas pipelines and its influence on the identity of the systems of gas consumption measurement. The offered principles of equivalence of the complex gas transportation systems allowed to construct the characteristics of the linear part of the Ukrainian system of main gas pipelines, the purpose of which is to define the exploitation parameters and to estimate the energy consumption for gas transportation. By the method of characteristics there was constructed an algorithm and was made calculation of percolation and total power of compressor stations under different conditions of system exploitation. There was done the research of dependence of total energy consumption for gas transportation on the depth of its cooling after compression while taking into account the energy consumption necessary for its cooling. In the dissertation there was described the research and development of the effectiveness increase system of gas cooling by water as a result of creating a high coefficient of heat transmission from gas to water. There was done analytical and experimental laboratory and industrial research to develop new methods of heat exchange intensification in the heat exchange units by application of physical fields. There was tested in the industrial conditions the method of heat exchange intensification, which differs from the known methods by its high technical and economical effectiveness and which includes the manual cleaning of the heat exchange units from scale and sludge.
