PT04 - Improving The Use of Plant Operators
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
Every plant has operators. They may be an untapped resource to improve reliability at a marginally low cost. The operators believe its his job is to make good product, do it safely, and prevent environmental excursions. ...
CST02 - Chandlersville and St. Paul: Unique Piping Vibration Issue in a New Centrifugal Compressor Installation
(Turbomachinery LaboratoryTexas A&M Engineering Experiment Station, [2019])
An unexpected vibration issue was seen at two of Tallgrass Energys recently installed compressor stations (Chandlersville and St. Paul) and was associated with certain operating conditions when specific combinations of the ...
TT02 - Compressor Selection for LNG Liquefaction Plants
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
One of the most critical components of an LNG liquefaction facility are the refrigeration compressors and their drivers, which have a significant influence on overall plant performance and production efficiency. Refrigeration ...
PL06 - Investigation on the influence of an inducer on the transport of single and two-phase air-water flows by centrifugal pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
This study explains the influence of an upstream inducer on the transport of single and two-phase air-water flows by a centrifugal pump. The inducer has generally a slight influence on single-phase flow. For two-phase ...
PL07 - Sand Management and Erosion Prediction in Subsea Multiphase Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
Over the past ten years, subsea multiphase pumping has accomplished extraordinary technology breakthroughs. The drivers are the oil and gas companies requirements for deeper and more remote subsea production satellites ...
PL04 - Understanding the Effects of Selecting a Pump Performance Test Acceptance Grades
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
There are good reasons for requiring the tightest test acceptance tolerances. That is why they are listed in industry accepted pump testing standards, ANSI/HI 14.6, ANSI/HI 11.6 and ISO 9906. There are also applications ...
CST17 - Case Study of Harsh Environment Impact on Gas Turbines Pre-Mature Failures in Malaysia Offshore Waters and Novel Approach in Resolving the Prolong Issues
(Turbomachinery LaboratoryTexas A&M Engineering Experiment Station, [2019])
A growing trend towards gas turbine applications in Harsh Environment which requires more challenging fuel and air qualities which has impacted the equipment reliability and long term durability. Major issues related with ...
CST09 - Analysis and countermeasure for Sulfide Stress Cracking of Centrifugal compressor
(Turbomachinery LaboratoryTexas A&M Engineering Experiment Station, [2019])
In case of copressors operated in evironment of wet hydrogen sulide, Sulfide Stress Craking could act critical mechanism of impeller failure. This case study deal with what make sulfide stress cracking and how to take a ...
CST10 - Resolution of High Vibration on Generator
(Turbomachinery LaboratoryTexas A&M Engineering Experiment Station, [2019])
The machine train consists of a HP/LP Steam turbine driving a Generator of 118 MW. The vibration was high on both the bearings of the Generator. The issue persisted for almost two years without the root cause being resolved. ...
CST01 - Hydrogen Recycle Gas Compressor Fouling Mitigation Using Higher Suction Temperature
(Turbomachinery LaboratoryTexas A&M Engineering Experiment Station, [2019])
During a normal run cycle the compressor performance started to decline (again) due to chloride contamination, a known issue. The usual approach was to shut the process unit down and turn the compressor off, then removing ...
