A new oil barrier Seal for dry gas Seals
Sealing Technology, 2009Co-Authors: Michael SattlerAbstract:The oil barrier/Separation Seal for dry gas Seals described in this feature is a co-axial gas lubricated Seal designed to eliminate the disadvantages of existing systems such as labyrinths or radial carbon ring Seals currently used in the industry. The aerostatic lift-off, achieved by means of differential pressure, provides no wear or contact during operation. This Seal can offer reliable operation with dry buffer gases with reduced buffer gas consumption and no restrictions on operational factors such as slow roll, turning gear and coast down. Safe operation in the event of complete main gas Seal failure is also possible.

Analysis of Historical Dry Gas Seal Failure Data
Volume 9: Oil and Gas Applications; Supercritical CO2 Power Cycles; Wind Energy, 2016Co-Authors: Tim AllisonAbstract:While proper design and maintenance of dry gas Seals is a well-understood topic, dry gas Seal failures are still relatively common. These failures can result in frequent repairs and costly downtime. Although several case studies of individual failures are available, relatively few large-scale dry gas Seal failure studies exist. Based on a review of existing literature, very little has been published on failure statistics aimed at improving Seal reliability. As a part of an industry-funded dry gas Seal reliability project, a failure database has been populated with information provided by both end users and original equipment manufacturers. The database includes details on dry gas Seal and Separation Seal configuration, Seal gas supply, operating history, conditions at time of failure, and failure symptoms, including any results from failure analyses performed by the survey respondent. In total, eight companies contributed 194 failures. Of these, 144 cases had root causes provided. From this database of failures, statistical analysis is used to determine common reasons behind dry gas Seal failures in gas compression service. Failure trends are identified based on data collected, and corresponding recommendations are provided for improving dry gas Seal reliability.
