Containment Seals For API 682 Second Edition
Abstract
The impending revision of API 682/ISO 21049 will include dry containment seals for the first time. These seals have been commercially available for over 15 years. This paper reviews the performance of these seals both in test and service in process plants to assess their capabilities of meeting API 682 target objectives of high reliability and emission control. Options for secondary containment are reviewed though the paper focuses on two principal types, dry contacting and noncontacting containment seals. Data from the test laboratory are related to field experience and recommendations made for when the two types of design are best applied. Both emission performance and seal reliability experience are drawn from refineries in the United States, Europe, and the Asia Pacific regions to validate operational expectations. Seal support systems for the two types of containment seals are described and reviewed.
