Dry gas seals are and is still considered as the standard sealing technology between the process gas and lubrication systems in centrifugal compressors. Dry gas seals are in the positive seal class and have the same basic design features as mechanical face seals, with one significant difference. The dry gas seal has shallow grooves cut in the rotating seal face located part way across the face.
