Abstract
Two-thirds of the pipelines in North America are transporting non-crude hydrocarbon products such as NGL, diesel, avaiation fuel, Copyright© 2020 by Turbomachinery Laboratory, Texas A&M Engineering Experiment Station propane, ethane, etc. This industry and the number of miles of pipeline is growing as the need for these products are increasing to record levels. Industry regulations and environmental concerns are becoming more stringent and demanding for the pipeline operators. Operators are looking for reliable and proven technologies to meet these growing demands. A pipeline is made up of a series of pumping stations to maintain process flows. Typically they are separated by 50-70 miles depending on the product being transported and the terrain. Usually one pumping station will have between two to three pumps in series with one pump at maximum line pressure. Operators are looking for increased reliability and better control of leakage, or lost product, during normal and catastrophic seal failures. Many end-users have in-house requirements on product containment and preferences on seal arrangement. These preferences are designed to enhance pump reliability, reduce maintenance costs, and improve run time, while providing the level of product containment required to meet environmental regulations. Two years ago, an innovative Non-Pusher Secondary Sealing technology was introduced to the industry to improve seal performance on crude services. This now proven technology has been utilized in services throughout North America. That same technology has now been developed into a seal capable of handling non-crude hydrocarbon applications. In this paper we look at the development, testing, and field deployment of a primary seal and a non-contacting, bi-directional secondary containment seal for non-crude hydrocarbon services.
