Most centrifugal compressors in refineries and petrochemical plants use shaft end seals which are either controlled leakage labyrinths (nontoxic/nonhazardous fluids only) or some type of fluid film seals using a liquid, primarily oil, as a barrier fluid. This article discusses the emerging technology of so-called dry seals. These seals use gas as the sealing fluid medium, and control the leakage to very low levels by limiting clearances between the rotating and stationary faces. Dry gas seal technology has progressed to where it can be applied to most centrifugal process compressors. The benefits and application considerations are presented.
