Fugitive Emissions Containment using a Dual Pressurized Seal and API Plan 53B
Abstract
Fluids that require limited emissions are often sealed using dual pressurized mechanical seals and sealing systems. API Plan 53B systems use a bladder accumulator to provide the pressure for the barrier fluid to isolate the process from the atmosphere. Reliable performance of these systems requires an understanding of the effects of temperature, barrier fluid volume, and seal chamber pressure to maintain a positive pressure differential. This case study will cover design considerations to improve performance, analysis of problems with an existing application, and the changes that were implemented to correct these problems.
