The issue is considered related to the increase of the technical level of piston compressor unit safe operation, including the valves of compressor cylinders effecting the overall technical and technological and economic indices of the compressor unit.
Means of increasing the working ability, resource and safe operation of gas-engine piston compressors are analyzed. In order to check the actual state of the piston compressor unit installed at the gas-lift compressor station, the compressor is put into operation and defects are identified during the work process in the gas-lift system with full load. If the defects are found, the work is stopped, and the defects are eliminated on-site.
The results of the study are shown, in which it was determined that the greatest number of failures is related to the valves of compressor cylinders of the 1st stage of gas-engine reciprocating compressors. To protect the equipment from the early wear, it is required to clean from solid inclusions and liquid hydrocarbon components before feeding into the 1st stage compressor cylinder.
For this purpose, it is recommended to install an additional horizontal gas separator of the new design at the suction line for cleaning gas from solid impurities and liquid hydrocarbon components.
Based on the conducted studies, the following conclusions were made: the most vulnerable node in the design of gas-engine reciprocating compressors is the valve assembly, in particular the components, like plates and saddle. The main reason for failure of these parts is the quality of the associated petroleum gas (presence of liquid and solid particles). Use of the new design at the suction line of the separator allows reducing the number of valve failures by one third.
