Vibration and NPSHr (NPSH₃), improvement of BB1 two stage pump reliability
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This case study discusses the impeller redesign of 10 8x15 BB1 two stages Amine pump in a Gas Sweeting Plant in Malaysia. The original pump was supplied in 1996 and after some design changes it had an history of recurring ...
Modern Methods to Detect Degradation in Centrifugal Compressor Performance and Use of Thermodynamic Performance Modelling to Identify Causes
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Detecting degradation in centrifugal compressor thermodynamic performance can be challenging. Machines can operate at different inlet and discharge conditions, different inlet guide vane positions, different speeds and ...
Multi-stage pump vibration caused by excessive wear ring clearance, Improper balancing, rotating stall
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Generally, the centrifugal pump vibration caused by mis-alignment, unbalance or bearing failure. But, I have seen two abnormal vibration phenomena in a multi-stage high pressure pump which has 13th stage impeller.First ...
Pump Tut - Precision Grouting of Turbomachinery
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Rotating equipment being installed in industrial environments, including refineries and chemical processing plants, are critically aligned with exact tolerances. When in operation, this equipment experiences heavy dynamic ...
Lube Oil Carbonisation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Carbonized particles can get deposited in housing oil seal clearances causing a partial rub like phenomenon. Friction caused due to reduced clearances because of accumulation of carbonized particles leads to shaft thermal ...
Development and Testing of a Supercritical CO2 Compressor Operating Near the Dome
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Supercritical Carbon Dioxide (sCO2) power cycles are a transformational technology for the energy industry, providing higher thermal efficiency compared to traditional heat-source energy conversion including conventional ...
Advanced Sealing Solutions for Non-Crude Hydrocarbon Services
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Three years ago, the Non-Pushing Secondary Seal (NPSS) technology was introduced to the pipeline industry and since then it has successfully addressed challenging pipeline services. Over 300 seals have been installed ...
Pump Tut - WHY MACHINES FAIL TO FOLLOW TEXTBOOK STATED RULES, AS ILLUSTRATED BY SHAFT CRACK AND ROTOR SELF EXCITED VIBRATION CASES IN CRITICAL MACHINERY
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This tutorial demonstrates some aspects of rotating machinery diagnostics where there is an apparent difference between the actual response of a machine and its expected behavior for a certain type of malfunction as typically ...
Overview of Grid-Scale Machinery-Based Energy Storage Technologies
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Grid-scale energy storage is needed to smooth variable renewable power sources and enable deep penetration of renewable power generators into the energy mix. There are many existing or developing machinery-based energy ...
Significant cost savings in Crude oil / Multiphase pump application by using Diamond seal Face material technology
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
In an upstream facility in Venezuela, Single Mechanical Seals in combination with API 682 Piping Plan 32 and 62 have been used in a Multiphase twin-screw pump application successfully over many years. It was clients target ...
