It is expected that the resource and energy field, which accounts for approximately half of
the compressor market, will continue to grow in the future. In this field, operating experience is
important, and high robustness and reliability are required of equipment. Among such equipment,
super high pressure range gas injection compressors have higher technical difficulty and therefore
have many technical issues that need to be solved. We have investigated the challenges that need to
be overcome and have developed super high pressure gas injection compressor (hereinafter
referred to as the super high pressure compressor) with high robustness. We have also
implemented verification tests that simulated all on-site operating conditions including CO2
concentration, pressure, rotating speed and changes in gas quantity in order to verify the
robustness. This report describes these technological development and verification test results.
