Mechanical Seal and Support System Considerations for Negative Temperature Hydrocarbon Services: NGL Processing and Ethylene Production Focus
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
There are many challenging mechanical seal applications throughout industry and perhaps none more so than those with negative operating temperatures, more succinctly, a temperature value lower than zero on respective ...
Highlights of Draft API 610 12th Edition
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
API 610 Eleventh Edition, Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries, has been updated to the Twelfth Edition. The Eleventh Edition was identical to the ISO 13709 Second Edition; however, API ...
API 682 Arrangement 2 Configurations - Considerations for Outer Seal and Support System Design
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
API 682, now in its 4th Edition, has made a concerted effort to accurately define and distinguish between different types of seal configurations available under the designation of ‘Arrangement 2’, including 2CW-CW, 2CW-CS, ...
Barrier And Buffer Fluid Selection And Considerations For Mechanical Seals
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The increased use of pressurized and non-pressurized dual mechanical seals has driven more installations to require the use of barrier and buffer fluids. While some end users have viewed the selection of barrier fluids as ...
Pulsation Analysis In Positive Displacement Pump Systems Using Waterhammer, Modal And Animation Software
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
High-pressure and flow metering systems often include a positive displacement (PD) pump and a network of piping and process equipment. Steady state pressure and flow dynamics (pulsation) is a common problem in PD pump ...
Navigating The Department Of Energy (Doe) Energy Conservation Standard And Test Procedure For Pumps
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Following the European Union’s (EU) lead, the United States (US) Department of Energy (DOE) began the long process of regulating the energy consumption of pumps in 2011 and, with support from the industry and advocates, ...
An End-User's Guide To Centrifugal Pump Rotordynamics
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
This tutorial outlines the basics of pump rotordynamics in a form that is intended to be Machinery End User friendly. Key concepts will be defined in understandable terms, and analysis and testing options will be presented ...
Applying The Energy Institute And GMRC/PRCI Guidelines For The Avoidance Or Reduction Of Vibration Problems In Small Diameter Piping Branch Connections
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Pump piping systems typically have small diameter branch connections that can develop vibration related fatigue failures due to mechanical excitation. Many installations do not take time to design small diameter piping to ...
The Selection and Design of Dual Pressurized Liquid Sealing Systems
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Dual mechanical seals represent one of the most common approaches to improving seal reliability and reducing process emissions. While the presence of the pressurized barrier fluid provides significant benefits, the challenge ...
Compression Packing: A Traditional Sealing Method Achieving High Levels Of Performance With Modern Technology
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The oldest and still quite common sealing device for pumps is compression packing, so called because of the manner in which it performs the sealing function. This tutorial will explain the technology and also clarify some ...
