Effective combination of on-site measurements and simulations for a reciprocating compressor system
conference paper
The capacity of two parallel operating BORSIG reciprocating compressors, installed at the OMV refinery in Vienna, had to be increased. TNO TPD was ordered to investigate the dynamic effects on compressors and pipe work due to the increased flow to avoid vibration and fatigue problems afterwards. For this purpose a pulsation and mechanical response analysis according the API standard 618, design approach 3, has been carried out. On-site vibration measurements have been carried out to check the dynamic behavior of the existing supports and modifications have been recommended. Moreover, the results are used in the mechanical analysis to achieve maximum accuracy. As a result of the pulsation and mechanical response study additional modifications were recommended to improve the dynamic behavior of the system. All the recommendations have been implemented and finally on-site vibration measurements of the modified system showed that the vibrations were allowable throughout the system. With this approach costly corrective additional measures afterwards were not necessary.
