IMPROVING THE EFFICIENCY AND RELIABILITY OF OPERATION OF TURBO-GAS COMPRESSOR EQUIPMENT FOR PETROLEUM ASSOCIATED GAS COMPRESSION

In recent years, the oil and gas and other industries have been increasingly used turbo-gas compressors (TGC). Prospects for use of TGC at compression stations (CS) is associated with their large motor resource, energy consumption and autonomy that do not require additional energy supply. The present paper is devoted to the creation of booster compressor stations with high reliability to ensure uninterrupted operation that meets high standards. In this connection, the collection of associated low-pressure petroleum gas for compressing and transporting it to the shore was the most urgent task in the acute shortage of natural gas. The performed analysis of the literature published showed that a significant number of works were devoted to the problem of ensuring a high level of reliability of compressor units. At the same time, there are no statistical data on failures necessary for deep analysis, the reasons causing certain equipment failures have not been sufficiently studied. This does not allow to provide the necessary level of reliability when upgrading the existing and designing new compressor units. It also requires the solution of a number of other problems related to ensuring reliability at the stages of design and manufacture of units. When developing and creating a new generation of TGC at the design stage it is necessary to carry out appropriate calculations to ensure the future safe operation of CS. To carry out these calculations, it is necessary to develop new scientific approaches and mathematical models on the basis of which it is possible to obtain more reliable results about the behavior of TGC in future operation. Similar calculations should be carried out for both existing and operating TGC in order to assess their suitability for work and to predict the life of the main working elements of TGC and CS in general.
